product description
Hot dip aluminum zinc coated steel plate, also known as aluminum zinc coated plate，Aluminum zinc natural color board，Aluminum zinc resistant fingerprint board，Aluminum zinc coated light plate，Due to the surface coating of the board being an alloy composed of aluminum, zinc, and other trace elements，Outstanding performance in terms of corrosion resistance，Gradually replacing galvanized sheet metal，Aluminum zinc plated sheet is mainly used for steel structure roofs，wall，Manufacturing of switch cabinet，Home appliance board production
The mixed structure of hot-dip aluminum zinc silicon coating has its unique advantages in corrosion resistance。When using aluminum zinc plated sheet，The first to corrode is the zinc aluminum eutectic in the rich aluminum phase skeleton，It has a good protective effect on incisions, just like pure zinc，The product after corrosion is not as easily detached as galvanized sheet，But it is stored precisely in the gaps between the aluminum rich phases of the skeleton，To some extent, it can prevent further corrosion of the coating。
