Currently, the primary methods for hot-dip galvanizing include the "wet method" (molten solvent method), the "dry method" (dried solvent method), the "lead-zinc method," and the "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 became more prevalent. Currently, the "dry method" is predominantly used worldwide for hot-dip galvanizing steel pipes.
