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