The main difference between Henan fireproof door and anti-theft door is that the anti-theft door has a good anti prying sealing performance. Generally, the door cannot be opened without a key after closing the door. The filler in the door panel is not fireproof material. high quality Class A fireproof door The security door must be marked with "FAM" and refer to the general technical conditions of security door GB17565-2007. Although the fireproof door is also made of steel, the door plate is filled with fireproof materials, and the thickness of the door plate also has different requirements. The steel door is an ordinary steel door. It also has a certain anti-theft function, but its anti prying performance is relatively poor. This type is common in street processing plants. Only Shanghai and Chengdu have local standards for fire and burglar proof doors, and those in other places can only be called fire entry doors, that is, fire doors that reach the standard of fire rated A or B, and (filled with fire door cores) Class A and B standards are generally divided by fire resistance time. At the same time, it meets the anti prying requirements in the following aspects: the door frame is 1.5 thick, and the steel plates on the front and back of the door leaf are 0.8 thick.

The door frame should be firmly fixed with the wall, and perpendicular to the corner. The vertical frame and bracing frame shall be straight and at the same angle to avoid planing and sawing. There shall be no less than 3 fixed points on both sides of the door frame, and the spacing shall not be greater than 800mm. Secondly, during the installation of the steel fire door, considering the bending deformation of the door frame, it is necessary to support the door frame with wooden braces in the width direction of the door frame.
