Hot dip galvanized products refer to finished metal components (processed by slitting, cold bending forming and other processes) that have a uniform and dense zinc layer formed on their surface through the hot dip galvanizing process. The zinc layer is metallurgically bonded to the metal matrix, with excellent corrosion resistance and mechanical strength. They are the mainstream choice for anti-corrosion components in infrastructure and industrial manufacturing fields. The production process relies on the synergy of hot dip galvanizing raw materials (zinc ingots, auxiliary alloys, etc.) and hot dip galvanizing agents (flux, passivator, etc.).
