Steel fire door and wood fire door product difference

On the structure
The thickness of the door leaf of the general steel fire door is 52~55mm, while the door leaf of the steel security door is generally 50mm,70mm and 90mm in the market of Guizhou. The weight of such a thick door leaf is only 30~40kg. If the anti-theft door is produced according to the technical standards required by the national security department, the thickness of the door leaf panel plate is 1.2mm, which does have a certain anti-theft effect. However, the "security doors" sold in the market in Guizhou today dare not call them security doors but steel doors and doors. Because, in an environment where steel is soaring and there is vicious competition in the market, there is a company that is willing to produce according to the national technical requirements.
Similarly, generally only the fire door leaf for fire prevention is required to be 50~55mm, and the thickness is different according to the fire prevention grade. Generally, hollow fireproof materials are sandwiched, such as asbestos and aluminum silicate, and their outer image is cotton. Therefore, the door will sound empty when knocked on. The fire door with anti-theft performance is solid, because the high-tech fire prevention board used in the middle looks like a medium density board, with high hardness and high density, therefore, the weight of the door leaf is about 70~80kg, which is twice as heavy as the steel door with 90mm door leaf. It goes without saying that anyone can prevent theft. It can be seen that the anti-theft performance of the wooden fire door leaf is stronger than that of the so-called "steel anti-theft door" on the market.
