Manufacturing Process
Galvanized coil is produced by dipping thin steel plate into melted zinc tanks, creating a protective zinc layer on the surface. The continuous galvanizing process involves dipping rolled steel plate in molten zinc plating tanks. Alloyed galvanized steel sheet features a zinc-iron alloy coating with excellent adhesion and weldability.
