Did you know? There are many anti-theft doors now, but the filling is actually very inferior. They are called \”anti-theft doors\”, but in fact they are not anti-theft at all.

When my home was renovated before , I found that the security door that came with my home was not a serious filling at all, but some inferior honeycomb paper, which not only has poor sound and heat insulation, but is also very prone to mold, let alone anti-theft.

What\’s more, it is filled with some construction waste and garbage. This kind of door core is really \”cheating\” .

Today, I will Let’s talk about the following “9 buy 9 don’t buy” security doors and see if you have stepped on any pitfalls!

1. Choose Grade A door

Security doors are generally divided into Class A, Class C, and Class D. Generally speaking, if you can choose a Class A door, it is best to choose a Class A door. As long as it is a serious brand, the quality specifications will be much better. , in terms of anti-theft, sound insulation and thermal insulation and sealing, they are even worse.

Class C D The quality of the products is even worse, and some of them do not meet the standards.

In addition, everyone looks at the Grade A door You should also look carefully at all times to avoid encountering \”Shen\” grade doors. This kind of anti-theft door that plays a word game has a higher probability of deceiving people with the filling of the door core.

2. Choose zinc alloy for steel plate

Security door For steel plate materials, I personally recommend choosing zinc alloy as much as possible.

Zinc alloy steel plate The advantage is that it is durable, not easy to rust, and more stable.

Cold-rolled steel plate security doors do seem to be thicker and heavier, but in fact they are prone to rust problems after being used for a long time, especially in some humid corridors and southern homes. Easier to rust

3. Do not fill with inferior honeycomb paper

The filling of honeycomb paper is not absolutely impossible, but you must be optimistic about what kind of honeycomb paper it is. The above The ordinary cardboard type honeycomb paper mentioned is completely inferior door filling.

But if it is filled with aluminum foil honeycomb panels, it will prevent theft The rigidity of the door will be much stronger. If you are pursuing cost-effectiveness, filling aluminum foil honeycomb paper is actually the best choice.

4. The sealing strip is promising

Security door Generally speaking, sealing strips are commonly used PU strips. This kind of strip is very cheap and has no problems when it is first used. However, over time, it is easy to age and become brittle, affecting the sealing effect.

Now I personally recommend using triple B for security doors Acrylic sealing strip can be understood as an upgraded rubber strip

Both the durability and sealing properties are much better than ordinary rubber strips.

5. Door leaf thickness

\”Anti-theft doors are not anti-theft\”, and thickness is also a key reason.

Under 90mm , I basically won’t watch it now. This thing is designed to protect against gentlemen but not villains. It can be easily broken into.

Only when the thickness of the door leaf is higher than 90mm can it truly protect against theft and forced break-in.

6. The hinges should be hidden

Previous anti-theft Doors and hinges are basically exposed, which affects the aesthetics on the one hand and creates a safety hazard on the other.

I now see that most brands of security doors have standard models with hidden hinges.

It should be said that even if the anti-theft aspect is not considered, in terms of aesthetics alone, I would also recommend that the hinges be made hidden, which will look much better.

7. Do not choose the one with cat eyes

You heard it right, I really don’t recommend choosing one with cat eyes when buying security doors now.

With cat eyes In a security door, it is easy to use this small hole to slide the door and pick the lock, which is a small flaw.

Relatively speaking, current smart cat eyes have Very mature, just buy a door without peepholes and install a smart peephole.

8. Choose grade C for the lock cylinder

Lock cylinders are divided into three levels: ABC. It is not that A is the best, but it has poor security, and C-level lock cylinders are more secure.

Generally speaking , the keys for C-level lock cylinders are relatively complicated, and it will take a lot of trouble for you to go to the stall where the keys are distributed. Considering safety, naturally you should choose C-level.

But it doesn’t matter if you choose the wrong one, later Locks can be changed individually.

9. Choose one-piece one

The one-piece body of the anti-theft door is stronger and stronger. In addition, the thermal insulation and noise reduction capabilities are stronger. This type of door is often more expensive, but it is worth it.

Too many solder points I really don’t recommend that you buy anti-theft doors. I have seen many cracked solder joints in the later stage, which affected the normal use of the door leaf. There is no need to be cheap on this.

All in all, the reason why anti-theft doors are not anti-theft is that in addition to the deception of the door core, the key is to buy or not buy the 9 above.I wonder if you have chosen the right security door for your home?
