Discontinuous hot-dip galvanizing is a process in which steel is immersed in a bath of liquid zinc (450°C). This involves a chemical process that creates a zinc-iron alloy composed of several alloy layers. Only the top layer is pure zinc.
This creates an extremely wear-resistant and robust protective layer that is inseparable from the steel. Unlike paint, which can peel off over time, a hot-dip galvanized coating remains intact and maintenance-free for decades.
