Lock on the gate door. How to choose outdoor locks for gates, advice and recommendations from experts

A gate lock or video intercom is a fixing device, which, in turn, can be of an electronic, mechanical or combined type. Designed to lock premises to prevent unauthorized people from entering them and to ensure the safety of property.

This is what an installed mortise lock on a gate looks like

Nowadays there are many types of locks that can be installed, and the price will pleasantly surprise you.

The simplest ones that you can make and install with your own hands are latches, latches, gate bolts and hooks. They were replaced by video intercoms, coded, electric and other types of locks.

Any person who is the owner country house or cottage, sooner or later he is faced with a situation where he is faced with the question of which lock or video intercom to choose. You will need a new lock if:

• the previous version is obsolete and has become ineffective;
• the intruders opened the old lock;
• you built new type fence that needs a modern video intercom.

You can make your choice as follows: industrial options, do just that and embed the lock with your own hands.

An example of a self-embedded lock

Locks for gates on the street should be made of stainless steel to resist atmospheric phenomena in the form of rain or snow.
A lock for a gate made of corrugated sheets can be of the following types:

• internal (mortise) lock;
• invoice, with handle;
• mounted;
• video intercom.

Installing a good-quality lock on a gate is often dictated not by any personal preferences or beliefs of the owner of the site, but by what design feature a particular fence or fence has. When choosing protective system that you are going to make with your own hands, you also need to take into account how important the power of the device is.

The price of a lock or video intercom largely depends on this factor. The better the lock, the higher not only its price, but also the level of protection it can provide.

If you do not need powerful protection, but a simple and symbolic closing device is enough, then there is no particular need to invest heavily in a lock - you can make it yourself. If you are going to install a rim lock for a gate with your own hands, it is important that the lock body is not only strong, but also solid.

This will help protect the mechanism from moisture and dust getting inside, which means it will increase the service life of the device and ensure its correct operation.

Market on at the moment crowded various options. To help you understand the modern range of locks and security systems, you need to consider their most common types, objectively weighing all the advantages and disadvantages.

Mortise locks

Scheme for installing a mortise lock on a gate

On summer cottages Cylinder mortise locks are often used, since they are equally suitable for both wooden doors and . But when using this type of locks, you must also take care of reliable waterproofing, since they are afraid of moisture.

Double-sided lock cladding is usually used as waterproofing. As already mentioned, the choice of lock often depends on the type of gate and wicket. For example, there are situations where narrow locks are necessary because there is no free space to accommodate the body protective device. Traditionally, this problem is typical for wickets and gates, the structure of which is welded from metal profile 40x40-40x60 or corner.

Cylinder mortise locks are specially designed for installation and insertion into the profile cavity.
This is one of the main reasons why they are the most popular among their counterparts. These locks can be found in a wide range at any specialized retail outlet.

Installing a mortise lock on a gate made of corrugated sheets is very simple; you can do it yourself. The step by step process will look like this:

Disadvantage for cylinder ones mortise locks there is also, and quite significant: compared to others defense mechanisms, they are most susceptible to hacking - even an inexperienced burglar will not leave special labor break such a lock in a short time.

Code locks

Code lock- this is a type of lock that is increasingly gaining popularity these days; they are distinguished by good reliability and are more difficult to pick or break. In such a device there is simply no place where a master key could be inserted, and the code value is almost impossible to guess or select at random.

The combination lock operates using a special movement of rings and pins. The mechanism occupies different positions when dialing different combinations numbers At correct set the code value causes the lock tongue to move.

The code value can be changed independently, if necessary, an unlimited number of times. A combination lock has some advantages over other types, for example, it does not require a key, which is especially good for those people who often lose them or forget to take them with them.

This is what an installed combination lock looks like

In addition, the code value can be communicated to all interested parties, which eliminates the need to make many duplicate keys.

If the key to a regular lock was lost and there is a possibility that it fell into the hands of ill-wishers, you will have to change the entire security system, while in a combination lock, when the code is disclosed to third parties, it is enough to change only its value to a new one. If there is such a need, then you can install a similar device, only equipped with an electric drive.

Padlocks

Padlocks have been used by humans for a very long time. This is the type of lock that, despite the passage of time and many more modern analogues, does not lose its popularity. Padlocks are widely used and are available in absolutely all specialized retail outlets.
These locks are distinguished by the simplest method of fastening, which does not require any additional manipulation or installation. This is most likely the secret of their enduring popularity. Technologies do not stand still and padlocks improve over time.

If previously it was necessary to use a key to open such a lock, now padlocks are widely used. combination locks. They combine all the ease of use of a conventional padlock, as well as the high efficiency and reliability of a coded one. The classic ones padlocks the bow was usually made of metal, and modern models it is most often made from high-strength cable.

Electromechanical or power locks

Electric locks are divided into two subtypes: overhead and mortise, but regardless of their type, such locks consist of at least two bolts.

Electro example mechanical lock for gate

Operating principle of crossbars:

• the first bolt is cocking; when the lock is closed, it hides inside and thereby launches all other elements of the mechanism, preparing them for the closing process;
• the second bolt is controlled by a solenoid, the moment voltage is applied to it, the entire system is activated and begins to move, after which the lock opens;
• The security system will remain in the “open” state until the door is reopened and closed, at which point a kind of system reboot occurs.

The electromechanical lock also includes regular keys, which can also be used to open the door. Such locks are most popular when installed on garage doors, since the system allows them to be opened even in the absence of power supply.

Set of all electromechanical lock parts for installation

IN recent years electromechanical locks are becoming more and more common, and they are increasingly being used when choosing a protective system for ordinary gates. There are electromechanical locks that operate on the basis of an electromagnet.

Security is one of the most important conditions for living in a particular territory. Housing that strangers can easily enter will never be in demand, much less provide comfort to the people living there. It is for this reason that everything more attention attention is paid not only to the height of the fence and how strong the gate and wicket are, but also to the mechanisms that prevent unauthorized entry into the territory - locks. This article will discuss only the most popular solutions, which will help you quickly navigate the current diversity of the market.

Basics: What to consider when choosing a mechanism

When choosing locks for street gates, it is important to consider a number of characteristics. The main properties of the mechanisms include:

• Thickness of the canvas. It plays a role both with padlocks and with mortise locks. Very heavy mechanisms will require reliable fastening, which cannot be created on a thin gate.
• Load. If the place is a walk-through, then you need to ensure that the selected model is adapted to high loads. Otherwise, the device will quickly fail.
• Security level. There are four in total, where the first is the easiest to hack, and the fourth is virtually invulnerable. The choice must be approached rationally.

It is highly desirable, but not necessary, that the gate lock be from an already reputable manufacturer. This will allow you not only to be sure of the quality, but also to know in advance about possible problems and difficulties with certain models, simply by reading reviews about them on the Internet.

Electromechanical mechanism from a well-known manufacturer

• moisture resistance;
• frost resistance;
• the presence of an anti-vandal system.

The first two points are especially important if you have to operate the locking mechanism in a harsh and cold climate. It is also advisable to pay attention to the size of the handle: small parts and levers can cause discomfort when used.

Access restriction mechanisms: types

In general, among the variety of models and types of locks, several main groups can be distinguished:

• electronic;
• radio controlled;
• electrical;
• mechanical.

Each type has its own advantages and disadvantages, which will be discussed further.

From a security point of view, the most reliable are electronic locks, since they eliminate the possibility of forging a key. The latter can be either an electronic card or tablet, or a fingerprint or a retinal scan. This technology didn't find it wide application, since it is quite expensive and does not justify its cost in standard cases. Such a mechanism for regulating access can be found in closed facilities, factories or companies - organizations where access by an outsider can pose a significant threat.

The remaining types are more friendly to the average person, and therefore are often found in private homes. Read more about each of them below.

Classic mechanical locking device

Radio-controlled locks: the optimal solution for the private sector

Radio controlled locks have one undeniable advantage: their housing is completely sealed. This allows you not to worry about the danger of moisture getting in or freezing of the mechanism.

Example of radio lock control

The very principle of operation of such a lock is simple: it is based on a sensor that picks up radio signals and activates the mechanism for locking or opening the door. Such a device is especially effective in combination with a surveillance camera or intercom. This allows you to control the flow of visitors and prevent strangers from entering the territory.

Locks of this type can be either mortise or overhead. The choice should be made based on the material of the gate.

Important! Even during power outages, it continues to perform its functions. Most models have a built-in battery.

Electric locks: advantages

Electric locks are a popular solution for summer cottages and private houses.

Example of a kit for an electromechanical lock

This type divided into two types:

1. Electromagnetic. It is based on the action of magnets. When electricity is supplied, such a lock is securely locked and cannot be broken, even if you pull hard on the handles. The only drawback is that in the event of an emergency power outage, some models without built-in batteries lose their functionality.
2. Electromechanical. In it, the locks are activated by a signal received by the locking device. When the power goes out, the lock's state is preserved, but it can be opened using a special key.

The undeniable advantage of this class of locking mechanisms is that they can be connected to monitoring and control systems:

• external surveillance cameras;
• video intercoms;
• combination locks;
• scanners.

This allows for increased security and also provides significant opportunities for monitoring and recording the identities of visitors. Electrical devices, as a rule, are little vulnerable to cold, but are sensitive to humidity.

Important! When installing the locking mechanism, it is necessary to pay special attention to the insulation of the wires and, if necessary, take additional measures to protect the wires from water and moisture.

Mechanical devices: golden classics

Mechanical locking devices are one of the very first types of locks. This type is very popular because:

• has an affordable price;
• modern models are difficult to hack;
• easy to install;
• often immediately combined with the handle mechanism.

The only downside is that the castle is absolutely not suitable for very cold or humid climates, as it is vulnerable in this regard. For example, contact with vag can provoke corrosive processes, and severe frosts will immobilize the constipation system. Of course modern market offers models with increased security, however, if possible, it is better to avoid locks that could potentially lose their functionality.

Nowadays, mechanical locks are often combined with combination or magnetic locks. This provides additional protection and increases safety. Externally, such a device may be no different from an ordinary pen: a socket for magnetic key or code panel may be located outside of it. This approach discourages intruders and thereby reduces the risk of intrusion on private property.

Installation of street locks

First of all, it must be said that it is easier to install a street overhead lock on a gate than a mortise one. In this section, both methods will be discussed, but it is important to understand that for the street it is much more rational to use overhead types of mechanisms.

For work you may need:

• self-tapping screws;
• screwdriver;
• welding;
• bit,
• sanding paper.

The process largely depends on what type of gate.

Mortise lock example

So, for corrugated sheets, metal or forged options optimal solution is welding. It securely fastens the case to the surface and prevents the device from loosening. It is important to remember that with this setup of the mechanism there is no room for error.

It is much easier to work with wood:

• Measurements. The place where the lock is attached is marked on the canvas or, if it is mortise, a mark is made on the end for the future groove.
• Sawing. If the lock is mortise, then use a chisel or other special tools a groove of the required depth is punched.
• Trying on the mechanism. The lock and its counter part are applied to the place of future fastening. If the operation of the mechanism is not hampered in any way, then you can proceed to the final fastening.
• Final fastening of the lock. At this stage, it is strongly recommended to use the instructions that the manufacturer comes with the device.

Rim locks are much easier to install. For their successful installation, you just need to position both parts correctly: so that the rods fit freely into the grooves, and no additional effort is required.

If we're talking about about a lock with a handle, you need to mark in advance both the location of the locking mechanism and the handle. The outer casing of the latter is often independent of the lock and requires additional fastening. It is important to ensure that it does not interfere with the operation of the lock, namely: it does not interfere with receiving a signal from the magnetic access, does not interfere with inserting the key, etc.

It is important to note that if the mechanism is electric, then the wiring is done last. It is recommended not to drive them along walls or the ground. Instead, you can run them underground, after wrapping them in protective material. It is recommended to cover areas on the gate itself with special profiles and flexible pipes– they will provide proper mobility and protection for the wires to the lock from moisture.

Example of a rim lock

If necessary, you can cover the mechanical lock with thick water-repellent material. Such a curtain will significantly extend its service life and also reduce the risk of corrosion. Both special materials and ordinary rubber can be used as a barrier to moisture.

When choosing outdoor access control mechanisms, it is important to take into account not only price and appearance, but also the characteristics of the model. Taking into account the peculiarities of the climate and future operating conditions, you can choose a lock option that will optimally meet all the requirements and at the same time satisfactorily perform its direct functions. Because external environment is often aggressive, it is important to remember a few simple rules regarding locking mechanisms:

• Initially high-quality installation. Exposed wires or lack of protection on mechanical locks will lead to rapid failure. To avoid this, it is worth initially optimizing the conditions for using the lock.
• Regular check of the lock. Periodic inspection will allow you to identify possible problems with the mechanism in advance and take measures to eliminate them.
• Selection suitable model. Even with the best care, a lock designed for temperatures of -30 degrees Celsius will not work at temperatures below this mark. It is recommended to study the documentation before purchasing a locking mechanism.

By following these rules, you can count on a long service life of the device.

Protecting one's own land from outside attacks has been relevant at all times. High stone walls are a thing of the past, but modern people are increasingly choosing to make fences that are easy to erect and are not expensive, but reliable materials, such as corrugated sheets.

The main access to the fenced area of ​​the site is through a gate, for which you need to choose a convenient and, most importantly, functional lock.

Requirements for a lock for a gate made of corrugated sheets

When choosing a lock, you need to pay attention to the following parameters:

• Availability of sealing against moisture and dust;
• Fault tolerance;
• Frost resistance of the structure;
• Level of protection against hacking;
• Possibility of locking with a key on both sides.

There is an opinion that installing a powerful lock for street gates made of corrugated sheets does not make sense, since you can enter the site by damaging the corrugated sheet, which will take less time than breaking a lock. However, damage caused to the fence will attract a lot of attention and will not go unnoticed, and the owners will be able to call the competent authorities without entering the site and without putting their lives in danger.

The presence of rubber (silicone, etc.) gaskets, seals and caps prevents moisture and dust from entering the lock. The mechanism itself, in turn, must be made of a reliable alloy and not have too small parts, which will extend its service life and prevent it from breaking down in case of icing. The lock must be locked on both sides with a key. This will prevent the gate from being opened by intruders who can simply climb over the fence and open the gate from the inside.

Types of castles

As a rule, locks are classified according to two parameters - by installation method and by type of control.

Among the types of fastening, there are three main ones:

Mounted

Such a lock is an independent structure, the opening of which implies its complete separation from the fixation elements.

This type of castle has been around for thousands of years.

Raw materials for modern industrial production The following metals serve as padlocks:

• Cast iron– cheap, not subject to corrosion, has a large margin of safety, but becomes brittle when the temperature drops significantly;
• Aluminum– light, but soft and deformable even under the influence of slight force;
• Steel– maintains integrity in all weather conditions, but is expensive;
• Brass– resistant to rust, but soft and expensive.

Also, locking devices of this type differ in the method of hanging:

• Open. The main element is a semicircular shackle, which, when deactivated, is removed from the lock body either completely or only on one side.
• Mushroom-shaped(or "fungus"). The closing part is a metal pin, which has a mushroom-shaped thickening at one end. It is completely protected by locking eyes, which makes cutting it down almost impossible.
• Semi-closed. A steel pin is used as a locking element, most of which is closed with lugs.

When purchasing such a lock, you should pay special attention to its depth and the length of the locking cylinder. Strongly protruding lugs or a large distance between them may prevent normal functioning designs.

• Closed. The locking cylinder is located in the lock body, when correct use it also closes the door lugs.

Eyelets for gates when using a closed type lock are usually made to order.

On average, the number of operating cycles that must withstand padlock, equals 100000.

Overhead

Installed directly on the door surface. WITH outside It can be locked with a key, and a rotary latch can be used instead from the inside. Modern overhead locks have more complex device, however, they have gained many fans due to their ease of installation.

According to the type of device, rim locks have the following varieties:

• Cylinder. Its larva moves to in the right direction regili or constipation. Most often, the keys designed to unlock this overhead mechanism are small and light.

A locking device of this type is extremely unstable to frost and blockages, so it requires constant treatment with silicone lubricants in cold weather, and it is also recommended to build special niches for it.

• Suvaldny. Reliable and resistant to force breaking. The lock is controlled by using a key with bits; it sets the internal metal plates (levers) in motion, influencing the locking mechanism.

Depending on the method of use, lever-type overhead locking mechanisms are:

• Unilateral. When closing, a key is used on the outside, and a special handle on the inside.
• Bilateral. The lock is controlled by a key on both sides.
• Rack and pinion. It opens by aligning the key and the grooves on the bolt. Simple and reliable mechanism the lock is not sensitive to low temperatures And high humidity. It may include one or two crossbars.

The rack-and-pinion closing element is extremely sensitive to misalignment and can jam.

• Electronic. WITH modern development technologies, so-called “smart” locks or smartlocks are becoming widely popular.

They come in several types:

1. electromagnetic;
2. electromechanical;
3. magnetic coded.

Opening the castle occurs by reading code information; the built-in scanner can be configured to recognize a barcode, fingerprint or iris.

Along with this, the closing device can be configured to receive a specific radio signal and be controlled remotely. The electronic electromechanical lock kit includes the mechanism itself, a scanner and a control unit.

Mortise

Internal lock mechanism size larger size his body. Designed for installation inside the door leaf, and does not have additional external protection. The mechanism of this closing device is made in two versions: lever or cylinder.

The lock control type is the method you use to open and close the system.

The following types of control of the closing mechanism are distinguished:

1. Mechanical. The mechanism is closed and opened by direct impact lock with a key. Such a device is easy to operate, easy to repair and, if necessary, easy to replace with a new one, and easy to install. Despite this, the selection of a high-quality mechanical lock is a matter of trial and error, which implies an increase in the level of danger for its owner and his property.
2. Code. To activate the lock, you must provide certain code information. Some modern analogues have a scanner for reading fingerprints or retina, which is also considered a way to remove encoding. Also similar types of locks include remote models configured to read radio waves emitted by the transmitter used as a key. Digital and alphabetic passwords, under the yoke of new technologies, are gradually becoming obsolete, which helps to improve the security and functional qualities of code systems.

Step-by-step instructions for installing a lock

Installation of a rim lock

1. As a rule, at a height of approximately one meter above the ground, a central metal strip is located on the gate. Usually, it is installed during the manufacturing process of the frame of the future door, but if there is no middle support structure, you need to weld it yourself.
2. Necessary attach the lock to inside wickets so that one of mounting holes the lock was at the level of the crossbar, and the core with the handle was either under the bar or above it. After this you can safely mark places with a marker, where the necessary technological openings will be located in the future.
3. Using a drill in the profiled sheet of the gate, along the contour, grooves are drilled necessary to install the keyhole and handle. Then their shape is finalized with a file.
4. Using the same tools you need manufacturebolt holes.
5. The whole process ends installation of a locking mechanism.

Installation of a mortise lock

1. Using a welding machine, a protective box for the lock is made, then it must be mounted on vertical rack wicket gate frame.
2. After which it is necessary mark the location of the grooves required for insertion and fastening.
3. A hole is cut with a grinder necessary for the functioning of the locking mechanism.
4. Above the fillet clean the edges of the cuts.
5. Then you need insertzamo to and install a cylinder in it, and then secure with self-tapping screws.
6. The next step would be installing handles, which are connected by a square rod and tightened with bolts.
7. Before use the mechanism is lubricated and the box is closed.

Mounting the strike plate

The strike plate is an element that the installation of any lock cannot do without. Its production cannot be called a complex process, however, and it is not worth working carelessly.

The main parameter that affects the installation of the return beam on the gate is the type of supports from which the frame is made.

1. Metal channel or pipe large diameter . IN in this case the recesses for the crossbar are drilled into the support body itself.

To do this you need:

• Leaving the lock open, close the gate.
• Place a mark at the point of contact between the support and the crossbar.
• Make holes along the marks and sand them.

1. Narrow corner. It is expanded by welding on a metal strip, in which all the necessary grooves will be made.
2. Small section pipe. A three-millimeter plate is mounted to it using a welding machine, then all the necessary openings are cut out on its surface.

Lock security classes

The reliability class of a lock is determined by determining the time required to break the locking mechanism or open it with a master key.

There are four degrees of stability:

1. Deactivating such a mechanism takes a few seconds.. Devices of this type can only get rid of annoying guests.
2. The autopsy takes place in no more than five minutes. Without a doubt, breaking such a lock will attract attention.
3. Opening the lock element will take more than fifteen minutes. This mechanism requires professional approach. It is often used for installation on gates and gates of fencing structures.
4. Can resist a burglar for thirty minutes or more. The price of this castle is relatively high, but it is worth it. It can only be opened by force or with the help of cutting tool. The locking element mechanism is made of high-strength materials that are resistant to drills.

Cost of locks for gates made of corrugated sheets

A good lock, regardless of its model, cannot be cheap.

When purchasing a closing mechanism of any type, the buyer pays not only the cost of the raw materials that went into its production. The more reliable the lock group, the more complex its internal structure, and the more time and effort it takes to manufacture it, and this, in turn, is the labor resource.

Its cost increases depending on the skill level labor force. Also, very often famous brands include the so-called “price per brand” in the price of their goods.

In other words, the company has been building its reputation for decades so that its name is associated with positive epithets, and having made a name for itself, it makes a small markup for its brand, the quality of which has long been proven.

Choosing as a manufacturer door lock a company that has proven itself with the best side and having the appropriate quality certificates, the buyer will avoid unpleasant surprises when using the closing mechanism.

If we consider pricing policy locks in the light of the currently available model range, we can come to the following conclusions:

• the most budget option is a padlock;
• rim and mortise locks of the same device do not differ much in price;
• a cylinder mechanism will cost less than a lever or rack and pinion mechanism;
• The most expensive locking devices are electronic locks.

1. You should not buy locks made in China. they have thin case walls and an unreliable mechanism. You need to buy certified products from reputable, good manufacturers.
2. When purchasing a locking mechanism it is necessary to check the functionality of each key included with it. If it is difficult to turn, then you should not use such a lock for the gate; it will not last long.
3. Choosing the best attachment mechanism give preference to products made of high-alloy steel, they are more resistant to adverse weather conditions.
4. A hinged locking element of a closed type is considered most resistant to hacking unlike other representatives of this model.
5. Before installing a mortise lock It wouldn’t be superfluous to coat the installation strip with silicone, and also treat each fastening screw, this will help create additional tightness of the structure.
6. Electronic, electrical closing elements do not work if there is no voltage in the network.
7. After installation is completed, the locking mechanism, with the exception of a hinged one, must fit tightly to the profiled sheet, this will prevent moisture from entering it from the inside.

There is no universal solution to the question of which lock to buy for a gate made of corrugated sheets. The natural and everyday properties of the area in which it will be installed, as well as the presence of certain functional properties, determine the preferred model of the closing device. Definitely not worth taking cheap models made of low-quality materials, but there is no point in spending money on expensive electronic analogues if their potential is not fully realized.

The website “Your Castle” presents wide range outdoor locks for gates and wickets from European and domestic producers. To choose the right one, you need to understand how they differ from each other various types locks

According to the type of installation, the lock can be:

• Padlock - a traditional padlock, which is characterized by its simple design, ease of installation and budget price. Due to its low burglary protection, it is most often installed where there is no valuable property, or in combination with rim or mortise locks to provide greater security.
• Mortise lock- mounted directly into the wicket door. It can be opened from the outside with a key; from the inside it can be opened with a key or a latch.
• An overlay lock for a gate is screwed to the gate itself, practically without damaging it. It can be opened from the outside with a key; you can install a latch or bolt from the inside. Different high reliability and ease of installation.

According to the type of construction, they are distinguished:

• Classic lock - has a mechanical type of security and opens with a key.
• A combination lock for a gate consists of a locking mechanism and a control panel. To open the gate, you need to set a certain code combination. If necessary, the code can be changed an unlimited number of times.

By type of locking mechanism:

• Level lock - consists of a set of plates (level levers), which, under the influence of the grooves of the key, rotate the lock mechanism. The degree of reliability depends on the number of levers. If you lose the key, you will have to change the entire lock.
• Cylindrical - the main part is the cylinder, which is responsible for recognizing the key and moving the bolts. The degree of protection depends on the complexity of the larva. If it is necessary to change the lock, it is enough to change only the cylinder.

How to choose?

To buy a gate lock that will fit exactly and function properly, you need to consider:

• dimensions of the lock (this is especially true for mortise locks for gates, where their size must be correlated with the width of the gate leaf);
• weather conditions conditions in which the lock will be used (moisture resistance, frost resistance);
• what degree of protection is required from the lock;
• passability (if you plan to have a high passability of people, then it is better to buy a lock for the gate, which can be opened from the inside with a latch, bolt or button).

Lock on a gate made of corrugated sheets

A gate made of corrugated sheets is a beautiful element of the entrance group. However, if there is no lock, it will not provide security. private territory. There are many types of locking devices for such gates, but they are all installed using the same method.

Mechanical locks designed for insertion into gates are divided into three categories:

1. Coded / electromechanical . They open from the outside as a result of dialing the digital code specified for the device. A latch or lever is provided for unlocking from the inside. The disadvantage of a combination lock is that the buttons wear out.
2. Level. Mechanisms of this type differ from others by keys. They have beards with varied teeth, corresponding to the system of thin plates of the entire mechanism. If you select the wrong keys, the door will not open. The suvald is an internal secret. The castle fully lives up to its name. The advantages of lever locks are long term service, the ability to enhance code protection, corrosion resistance, reliability and affordable price. The disadvantage of locking locks with a secret is the key large size. Consumers also find it unreliable to unlock the gate with such a lock both from the outside and from the inside.
3. Cylindrical . A special feature of these locks are needle-like devices, which together must match the key marks. English castle- another name for a cylindrical mechanism, equipped with a compact key. The device is easy to repair, but is sensitive to moisture and dust.

According to the installation method, locks for gates made of corrugated sheets are classified as:

• Mounted. Not a very convenient option, which is considered the least reliable. Attackers can break padlocks without difficulty.
• Invoices. The locks are easy to install and not burdensome to operate. You can put the gate on the frame.
• Mortise. The lock, which is difficult to install, is unlocked with a key from the street side of the gate. The door must be locked from the inside with a latch or lever.
• Rack and pinion. A rarely seen design consists of a bolt that moves along hinges. In turn, the hinges are welded to the fence or gate. The mechanism is easily hacked and therefore not reliable.
• Electromagnetic . Usually mounted on the entrance doors of multi-storey buildings. Masters tune the lock mechanism to the electromagnetic fields of specific keys. The device opens as soon as the key is at a special recess.
• Radio wave. The mechanisms operate on the principle of a car alarm. They can be opened only with the help of special equipment, however, it will not be possible to install a radio wave lock with your own hands due to the need for skills and a sufficient amount of time.

The most common types of locks for gates made of corrugated sheets are mortise and overlay devices. Locks for outdoor gates differ from indoor door locks by a narrowed bar and a small distance between it and the center of the mechanism.

How to insert a lock into a gate made of corrugated sheets

What does the castle consist of?

Let's look at how to insert a padlock into a gate made of metal profiles. The mechanism does not damage the integrity and strength of the structure. It opens and closes from the outside with a key, from the inside - with a key or latch. Installation of the device does not require disturbing the door leaf, which pleases the owners. But for neat, reliable fastening, it is important to provide a special platform on which the lock will be placed.

The fixation location may look different:

• Like a solid metal space located on the inside.
• Like a connection of frame sections running from top to bottom and across the center of the gate.

Inserting a lock takes place in three stages:

1. Marking the workspace. The lock is leaned against the door leaf and the fixation points and the area for the lock cylinder are marked.
2. Drilling marked holes. The diameter of the drilling tool is selected according to the diameter of the bolts and screws. The hole for the lock cylinder is made with a diameter corresponding to its size.
