The difference between a security door and a fire door is that the main function of the security door is to prevent prying and better sealing performance. Generally, you can't open the door without a key outside the back door, and the filler in the door panel is not fireproof material. The security door must be marked with the word "FAM" and refer to the General Technical Conditions for Security Doors GB 17565-2007. Although the fire door is also made of steel, the door panel is filled with fire-proof materials, and the thickness of the door steel plate also has different requirements. Steel doors are ordinary steel doors, which also have certain anti-theft function but poor anti-prying performance. Generally, street processing factories are like this.
