The so-called metal doors, steel doors, entry doors are "playing ball", is avoiding the strict provisions of the state security doors. Compared with the security doors, some metal entry door frame, door and lock around the lack of reinforcement plate, reinforcement part, the use of steel plate thickness is not up to standard, poor product quality, safety performance is not fundamental protection. Burglar-proof door is short for burglar-proof security door, it is the same concept as the pry-proof door, so the steel door is not equivalent to the security door.
Burglar doors can be made of different materials, but only to meet the standard test qualified to receive the security technology to prevent the production of products licensed to be called the door security doors. At present, because the product appearance is very different, many consumers are confused, often misled by dealers.
Steel doors in appearance and security doors without any difference, but the security door steel plate thickness, impact strength, the implementation of the national mandatory standards; and steel door is the implementation of corporate standards, the quality is far inferior to the security doors, security is poor, not to achieve the anti-theft effect.
