1. Choose according to the size and opening direction of the door

There are generally four specifications for household standard doors, represented by a four digit number consisting of the width and height of the building opening. For example, the width of a door opening is 1 meter and the height is 2.1 meters. Its specification is called 1021, and commonly used specifications include 0920, 0921, 1020, 1021, etc. The opening direction of the door is divided into inward opening and outward opening, which are further divided into left opening and right opening. Users can choose the opening direction of the door according to the direction that is convenient for opening.

2. Pay attention to the surface quality and safety of anti-theft doors

The thickness of the steel plate used for the door frame of the steel anti-theft door should not be less than 2mm, and the thickness of the steel plate used for the front and rear panels of the door leaf is generally between 0.8-1mm. The national standard requires that doors must be stamped with a steel seal. The grade steel seal of anti-theft doors is generally located at the hinge edge of the inner door. If the door you see is not stamped with a steel seal, it does not meet the requirements of the national standard and is not an anti-theft door.

3. Pay attention to the safety of anti-theft door hardware components

The anti-theft performance of anti-theft doors mainly depends on the performance of keys and locks, so when selecting anti-theft doors, it is necessary to check the performance reports of keys and locks. The lock inspection report will directly indicate the time of the anti lock technology opening experiment, which is usually referred to as a few minutes to open the door lock. If the merchant cannot provide the lock cylinder detection report, it means that the timing of the anti-theft technology opening experiment for this anti-theft door is unknown.

4. Choose professional brand anti-theft door products

Brand is a symbol of product quality and service. Brand mainly refers to the product brand and distributor brand. When purchasing anti-theft doors in the market, it is best to go to a formal large-scale home building materials city to buy. When purchasing, attention should also be paid to the "FAM" logo, company name, and execution standards of the anti-theft door. Only doors that meet the standards can be both safe and reliable. When customizing or purchasing anti-theft doors, qualified products should be purchased from manufacturers who have obtained the "Production License Registration Certificate" issued by the public security bureau.
