Zinc plating of lifting chains: The main purpose is to prevent corrosion. Types include: Galvanizing: Electroplating a thin layer of zinc on the surface of the chain. It has relatively low cost and a bright, smooth appearance. Its anti-corrosion ability is moderate and suitable for indoor or environments with weak corrosivity. The salt spray test time is usually around 48-72 hours. Hot-dip galvanizing: Immersing the chain in molten zinc to form a thick and adherent zinc-iron alloy layer and a pure zinc layer. This method is particularly suitable for outdoor, humid, and corrosive environments containing salt spray (such as ports, docks, ships, chemical plants, open-air storage yards).
