Burglar-proof doors: features of choice

The main task of the front door is to protect the home from hacking, so it must be made of high-quality materials using a special technology. In order to choose the best option, you need to familiarize yourself with all the features of anti-burglar structures. Knowing all the nuances of the right choice, you can secure the house to the maximum.

The front door is a shield at home, so it must have a number of properties. In order to have a stable and durable base, it must consist of a steel multi-layered faceplate, a reinforced frame, an armored locking structure and a monolithic triplex in a glass block with a reinforced reinforced grid.Inside the canvas should be non-flammable and insulating filler.

Entrance anti-burglar panels should prevent hacking by cutting loops or opening scrap. They must be resistant to mechanical damage, including shots from a firearm or undermining. Even when towing a small truck, the door should not give in to pressure and stay in place.

The burglar-proof design cannot be jacked, sawn with an electric saw or holed. Even gas-flame welding should be powerless in the way burglars get inside the house. Of course, according to research, any door can be opened, but a high-quality canvas should resist hacking as long as possible. During the time that the attackers will mess with the locks, someone may notice them and call the police.

It is not always burglar-resistant entrance panels set rich people who are most worried about their property.They are often purchased for financial institutions, museums and office buildings. Yes, and the average citizen is interested in their own protection, so often pays attention to precisely such structures.

Vzlomostoykie cloths are soundproofed and have a low thermal conductivity. They are equipped with high-quality door fittings, which is designed for multiple opening and closing. A wide range of products allows you to choose an interesting design that will decorate the facade of the house.

Anti-burglar structures should be selected taking into account their classification. To protect the home experts recommend purchasing products of 2 or 3 classes. It is believed that the weakest in stability are class 1 doors, and they are usually placed at the entrance to the interior.

At class 2 there are locking devices and reliable locks, which allows you to protect the building from being hacked. Even experienced masters can not always cope with this task. The most reliable are the panels of 3 classes. They are equipped with crab and multi-point locks, and the locking pins enhance the stability of the door frame.But such serious constructions are not easy to find in the store of doors, as they are mainly produced on request in a single copy.

There are 4 and 6 classes of burglar resistance. They differ in that the door of the 4th class is able to resist the shelling from a machine gun, and the product of the 6th class will withstand a shot from a rifle. Vzlomostoykost design involves full compliance with international standards and certification. In order to open it should take at least 10 minutes, and if it is 4 class, then at least half an hour.

The peculiarity of the choice of such a specific door construction is the selection of not only sustainable, but also a multifunctional option. The armored cloth must have a company lock, which is resistant not only to opening, but also to creating an impression.Inside the canvas should be an optical eye and a protective chain. Door handles and hinges should be so strong that they should not be cut down or be subject to other mechanical stress.

Most people, buying the entrance anti-burglar structure, are guided by the thickness of the metal that makes up the door panel. Following a logical opinion, initially it seems that the thicker the metal, the stronger and stronger it is. The massive door inspires confidence, but in fact, it is not always that such a product is highly resistant to burglary.

The peculiarity of the door panel with anti-burglar system is that there is no clear dependence of metal thickness on the quality of the product. If the metal sheet has a thickness of more than 3 mm, it can be assumed with a high probability that low-quality material was used for its manufacture. This is due to the fact that in order to increase the rigidity of the web, it is necessary to provide a greater thickness of the metal.

Vzlomostoykie door products have a complex structure, which with a certain calculation should strengthen the strength with the help of a special system of internal stiffeners. Many technical ideas are aimed at reliably confronting the door to any kind of hacking, even in the absence of external metal sheets. Such a product is expensive, since for its manufacture uses a special complex technology.

To date, on the building materials market, door designs can be purchased, the metal thickness of which is 0.8-1.2 mm. In this case, most of the falls on the paintwork. This sheet is very soft and unstable, and therefore does not have resistance to opening. By purchasing such a door, you should not expect that it will be able to withstand the load more than the usual wooden structure.

Hot rolled or cold rolled metal can be used in the production of burglar-resistant panels. High-quality steel is used for the manufacture of cold-rolled sheet, while low-quality raw materials are used for hot-rolled sheet metal. Therefore, the doors of hot rolled steel are heavy and thick, but do not have good performance characteristics.

Cold-rolled production method is good because it provides for the complete removal of dross. It’s almost impossible to do it manually, so special technology is used in manufacturing. Additional cold rolling of steel provides sheet with additional rigidity and strength. He has the ability to bend without cracking, and he has virtually no irregularities.

Before you go to the store door and buy your favorite model, it makes sense to study customer reviews on thematic forums. The quality of security doors is discussed not only by users, but also by the manufacturers themselves.

After carefully reading the views of Internet users, you can consciously come to your own decision:

• People who prefer products from hot-rolled raw materials, especially note their availability. Manufacturers of such products are trying to save money and acquire low-quality metal, which is made by welding technology. Therefore, the installation of such a model will not differ from the purchase of a conventional wooden door.
• It is best to give preference to cold rolled steel models, as they have several advantages. They have a smooth surface and the same thickness, and they have no residual stress. These doors can not be broken or ruined. And due to the absence of scale, they are not susceptible to corrosion.

• The thickness of the metal sheet at the selected door should be 1.2-1.5 mm. Such a panel will have a small weight and affordable cost.
• It is especially important when buying a burglar-resistant design to pay attention to the manufacturer. If it is not well known, then it may use poor-quality materials during production. Therefore, it is also important to check all its related documents.
• In addition to its operational properties, the entrance or interior doors should have an aesthetic appearance. On the modern market a wide range of models with a diverse design. When deciding on the purchase of a particular canvas, you need to focus on the overall style of the facade of the house.
• If the buyer has questions when choosing the front door, then you need to contact a consultantwhich is available to tell about all the advantages of the models presented.
