In addition to the role of ordinary doors, fire doors have the effect of preventing the spread of fire and the spread of smoke, ensuring the safe evacuation of personnel, and is called the "last door to protect lives." However, because the appearance and material of the fire door is not very different from the ordinary door, the masses are difficult to identify when purchasing, and it is easy to be deceived by illegal traders.

The name of the manufacturer on the nameplate of the fire door shall be consistent with the product type approval certificate and inspection report. The product name shall clearly indicate that it is a fire door product, and whether there is a large “S†identity on the fire door; Touch the surface.
