The surface layer of the coated steel plate is not easy to be corroded, and the PMMA/ASA alloy co-extruded anti-corrosion film on the upper surface layer can last for a long time. Because of the low density of the surface material and the high hardness of the substrate, the weight per unit volume is light in metal materials. of.
For common corrosive chemicals such as sulfur dioxide, sodium hydroxide, ammonia, heptane, sodium oxide, hydrogen hydroxide and other corrosive chemicals, it can achieve a good anti-corrosion effect and improve the use of buildings. Longevity can save time, worry and effort for users.
