A good "security door" is the protector of life and property. Anti-theft doors have flat-open, push-pull, folding, fence and other structural forms, and the main use of the flat-open type. When purchasing, focus on the five factors of anti-theft performance and quality:
1. The conformity certificate must have the inspection certificate issued by the statutory inspection agency, and the safety technology prevention product permit issued by the safety technology prevention department of the provincial public security department (bureau) where the production enterprise is located.
2. Security level Security door security is divided into A, B, and C3 levels. C-class anti-theft performance is the highest, B-class is second, A-class is the lowest, most of them are A-class on the market, and they are generally suitable for general families. Most of the A grades are A grades, which are generally applicable to ordinary families. Class A requirements: all steel, flat open and fully enclosed, under the cooperation of ordinary mechanical hand tools and portable power tools, the weakest link can resist abnormal opening time ≥ 15 minutes, or should not be able to cut out a wear A 615 square centimeter hole through the door.
3. The material is more commonly used stainless steel at present, beautiful, durable and anti-corrosion. There are two main points to see: â‘ The materials of stainless steel anti-theft doors that are currently popular are mainly grades 302 and 304; â‘¡The thickness of the steel plate is not less than 2cm. The thickness of the steel plate in front and back of the door is generally between 0.8cm and 1cm Skeleton and reinforcement board.
4. Anti-theft doors with qualified locks generally use three-position locks or five-position locks. Not only the door lock is locked, but the upper and lower cross bars can be inserted and locked to fix the door. Most doors are also embedded with rubber sealing strips on the door frame, so there is no harsh metal collision when closing the door.
5. Check the quality of the process to see whether there are defects such as open welding, unwelded, leaking welding, etc., and whether the joints of the door leaf and the door frame are dense, the gap is uniform, the opening is flexible, and the paint plating is uniform, firm and smooth.
Finally, when purchasing, you should also pay attention to the "FAM" logo of the "anti-theft security door", the name of the company, the implementation standards, etc. The door that meets the standards can be safe and reliable.
