Can be submerged for recycling use, in line with the requirements of green buildings. Impact tests fromA 15mm diameter steel ball weighing 500g dropped from a height of 500mm. The ball undergoes a gradual 180-degree bend test using a manual press at room temperature, without any peeling or cracking. Salt corrosion resistance test involves cutting a cross-section with a knife to just touch the aluminum plate, subjected to a 5% salt solution at 35°C for 360 hours. Acid corrosion resistance test, extending from the rust stains, involves 10% HCL, CH3COOH, and H2SO4 for 100 hours without any surface change. Temperature test, conducted in extreme Arctic cold (-50°C) and equatorial heat (60°C), applies functional quality control policies to ensure stability and efficiency.
