Can you tell me how to identify the quality of kitchen security doors?

Identification of security doors

First, the seller is required to present the "Test Certificate" from the relevant department to check whether it meets the technical requirements of the national mandatory standard GB17565.1998.

Second, remove the cat eye, doorbell box or lock handle and check the internal structure of the door body. There should be several reinforcing steel bars inside the door to organically connect the front and rear panels of the door. It is best to use asbestos and other materials with fireproof, thermal insulation and sound insulation functions as fillers inside the door.

Third, check whether the lock uses a special anti-theft lock that has been tested by the public security department, and whether there is a reinforced steel plate for protection at the installation location of the lock.

Fourth, check the workmanship quality of the product, whether there are welding defects, whether the fit between the door leaf and the door frame is tight, etc.

Fifth, weigh the weight of the anti-theft door. The weight of the regular anti-theft door is not less than 40 kilograms.
