The gap around the security door is relatively large, whether to fill cement or how to deal with it

Are you from Beijing? In Beijing, there are specialty stores in various large home furnishing markets.

Use Qunsheng bar, the old brand is trustworthy, the spring time to do the anti-theft door is not long, you should pay special attention to some details when buying!

It is best to look at the thickness of the filling and steel plate, you can look at it when installing the anti-theft door, generally you can see what is inside by unscrewing the cat's eye from the door, if there is a cat's eye has been installed, and it can't be screwed down, you can see it when the door is locked. Consumers can knock on the anti-theft door with their hands, and the sound sounds solid, indicating that the thickness of the steel plate is enough, and the filling is real. If the sound sounds "poof", it means that the thickness of the steel plate is not enough.

Generally speaking, it takes a month to customize the security door, but the custom time of some security doors will be a little faster, from the beginning of the booking to the door-to-door installation, it can be completed in almost 25 days.

How slow is customization, and I haven't heard of custom-made security doors. If you want a high safety factor, go to a regular place and buy a good one.
