[0002] The helipad is the main activity area for helicopters and plays a vital role. The aluminum alloy materials on the helipad are prone to electrochemical corrosion with certain materials in the fire-retardant coating, affecting its structural stability. Therefore, the aluminum alloy surface is not suitable for fire-retardant coating. Aluminum alloy has poor high temperature resistance and quickly loses strength above 150°C. As a structural system, the aluminum alloy material must ensure the material performance during a fire to ensure the stability of its structural system so as not to affect the normal use of the helipad. The possible fire situations on the helipad are divided into: fire on the roof / ground related equipment and facilities, thereby affecting the aluminum structure support columns of the helipad; when the helicopter takes off and lands on the helipad, static electricity may occur due to aviation fuel leakage, resulting in open flames; if the fire in the above situation cannot be extinguished in the first time, the fire will become larger and affect the helipad.
