Hot Dip Galvanizing Process Coating Fabricated Steel Galvanized Carbon Steel Pipe
Proper surface preparation is critical, as zinc will not react with unclean steel.After surface preparation, the steel is dipped in the molten (830 F) bath of at least 98% zinc. The steel is lowered into the kettle at an angle that allows air to escape from tubular shapes or other pockets, and the zinc to flow into, over, and through the entire piece. While immersed in the kettle, the iron in the steel metallurgically reacts with the zinc to form a series of zinc-iron intermetallic layers and an outer layer of pure zinc.
