Sound insulation, warmth, fire prevention, so the country's requirements for the internal filling of the anti-theft door must be aluminum silicate rock wool, because aluminum silicate rock wool has good thermal insulation, fire and sound insulation performance, only the security door or steel wooden door is filled with high-strength environmental protection materials (high-strength honeycomb paper core).

The four types of fillers allowed by the state are: honeycomb paper (i.e., carton board), perlite cement, rock wool, and aluminum foil. Generally, the fireproof door of the real estate is made of cement or perlite, which is good for fireproofing, and the disadvantage is that it increases the weight of the door leaf, which will deform and crack the hinge for a long time, causing the door leaf to fall. Honeycomb paper is the most resistant to cheap filling, which can be corroded due to seasonal changes and other changes, resulting in an empty shell. >>>More
The lock knob inside the security door controls a deadbolt. With this small knob, when people are in the door, if they are too lazy to use the key to directly lock the anti-theft door, through this knob, it will save the situation of using the key to lock the door. Moreover, if the door is not locked inside, the door can be opened outside, but after using this small knob to reverse the lock, the security is improved. >>>More
