Hot-dip galvanising is a proven process for protecting steel from corrosion. There are two basic coating processes in hot-dip galvanising: batch galvanising (discontinuous) and strip galvanising (continuous). In both cases, the component to be protected is immersed in a bath of molten zinc or zinc alloy. This creates a well adhering zinc-iron alloy layer at the points of contact, while a very robust zinc layer forms on the surface above. This coating protects the component from corrosive influences.
