Currently, the main methods of hot-dip galvanizing include the "wet method" (molten solvent method), "dry method" (dried solvent method), "lead-zinc method," and "protective gas reduction method."
The earliest method used for hot-dip galvanizing steel pipes was the "wet method." However, due to quality issues, the "dry method" gradually replaced it. Currently, the "dry method" is predominantly used worldwide for hot-dip galvanizing steel pipes.
