Hot dip galvanizing
Hot dip galvanizing is one way of protecting metal from rust. When immersed in liquid zinc at a temperature of around 450 degrees Celsius, a resistant alloy of iron and zinc is formed and above it a very adhesive pure zinc layer. In hot-dip galvanizing, a distinction is made between (discontinuous) batch galvanizing and (continuous) strip galvanizing. Both are standardized procedures according to DIN.
