You may have seen in YouTube how attackers break open cheap doors. The paradox is that they got it pretty simple and using a simple tool. You might say, “So this is cheap! But dear, armored, for which everything is like in a safe, let them try! ”The logic is quite understandable. For some reason, we all think that the more expensive the better, safer and stronger. People are often ready to lay out their last hard-earned money, but only to certainly protect their property from plunder. Well, when it is possible to get a really high-quality and reliable door for this money. But there are also situations when the saying is true: “not all is gold that glitters.” Let's try to understand this difficult question. In the article we will tell how to choose a safe door for an apartment.

There are two basic rules that you definitely shouldn't do:

Do not deal with dealers.
Do not acquire the door in the company, which for some reason makes you suspicious or doubtful.

Most likely, in the door market you will begin to offer a variety of options for powerful door panels with the prefix "safe". Eyes scatter, and you are confused, what to choose? Let's approach this issue in a complex.

Criterias of choice

The thickness of the metal from which the door is made. If it is tselnognaya steel, the thickness of the metal must be at least 2 mm. If the door leaf is made of alloy steel, then at least 1.5 mm.
Class lock (as far as the mechanism for burglary is reliable).
The presence of heat insulation (how tightly the heat insulating material fills the inside of the doorway). It is clear that you will not be able to verify this. But ask the seller a question about it.
Weight. If the door weighs up to 100 kg, but it has only two hinges, it is better to abandon the purchase. In due course loops simply will not sustain such weight and that day when you simply cannot close a door will surely come.

Door weight up to 70 kg - 2 hinges.
Door weight up to 100 kg - 3 hinges.
Door weight over 100 kg - special upgraded hinges on the bearing.

If you choose a door for an apartment, the main thing is to do it without fanaticism. The door up to 70 kg on two hinges is quite suitable here. However, everyone in this case is free to decide for himself, based on his circumstances and financial capabilities.

What should be locks

Now more about locks for safe-doors. We are well aware that the safety and security of your property depends on the quality and reliability of the locking mechanism and the thickness of the metal of the door leaf does not play a special role here. What kind of locks in the safe door should stand? By itself, the castle has a certain class - from first to fourth. What does this class mean? It denotes how much time an attacker can conditionally spend on hacking the mechanism.

Second class. Security properties are normal. Resistance to opening for at least 5 minutes.
Third class. Security properties increased. Resistance to opening not less than 10 min.
Fourth grade. Security properties are high. Resistance to opening for at least 30 minutes.

For example, for an apartment door there is even a GOST, which strictly regulates the level of the class of locking mechanisms in the doors of apartments. The lock on the apartment door must have a class either second or third, not higher. The fourth class of the castle is recommended to be installed only in cases when there are some special values in the apartment or in the house. And what to consider as special values, this is someone like that. Of course, the best option is a third-class castle. If you want to see exactly that on your door, please. As they say, every whim for your money. I must say that in this case you should not skimp, because good locks, like good doors, are not cheap. A complex locking mechanism will not immediately succumb (if at all) when you try to break it.

Remember that the best and reliable safe-doors are doors that have different locking mechanisms.

No master key is able to break the cylinder lock, which uses a key-card. More hardy on the suvaldny break. It will therefore be very good if both of these types are used. Please note that the distance between the locking mechanisms should not be less than 300 mm. An indicator of good quality, reliability of the whole door structure as a whole can serve such a nuance as a separate handle location.

What do the professionals advise

What else do you need to know about the door? Make sure that the door design is present:

Pretense This is a constructive projection that will not allow your door to be removed from its hinges.
Deviator. Additional constipation, which are activated by the central lock with their subsequent fixation, either from below, or from above, and, possibly, on both sides simultaneously. Protects from force opening.
Rigel. This is a metal rod that is a locking device. It is operated together with the deviator. In the door of such rods should be up to 5 pieces maximum.

The presence of all these protective mechanisms in addition to locks will make your safe door a "tough nut to crack" for intruders. However, you should not dwell only on the thickness of the metal and the locking part of the door leaf. There are more questions that you definitely need to find out.

Are there any ribs? How they are distributed throughout the door leaf.
Has a curved profile been used in the door structure?
Is there protection near-lock zone. Usually these are lining of armor and manganese lock plates.
What is the doorway box made of? A rolling profile must be applied.

As noted above, we will not be able to personally verify all the nuances, because we will not be able to see the interior of the finished door, only the external one. And yet there is one simple way to help us ensure the integrity of the manufacturer. Lightly push the door already installed in the box. In the event that the door gives in easily, it is safe to say that it is made of a thin off-grade metal. It is better to immediately abandon the services of the company that installed you this fake. Believe me, whatever the size at the door, you have to make tangible efforts to make it surrender. Like this.

What's inside

What else can be said about the selection criteria for a suitable safe door?

You can not discount the heat and sound insulation. After all, no one wants to see other sounds from the doors of the muzzle and into the apartment. Therefore, you need to make sure how tight and hermetic the porch is adjacent to the box, whether the corresponding sealing gaskets (usually D-shaped) are located along its contour and also along the contour of the door leaf. In terms of heat conservation, it is best if the door filler is not foam or foam, namely, basalt wool and at least 5 cm thick.

I want to believe that this article about the safe door will help you a lot. Therefore, protect yourself and your property with safe, high-quality and inaccessible safe doors and sleep well.
