| Electrolytic Zinc Coated Steel |
The product has an enhanced corrosion-resistant characteristic through an electrolytic galvanizing process to Cold-Rolled Steel, Unlike Hot-Dip Zinc Coated Steel, it has less amount of zinc coated but retains corrosion resistance due to its evenness of the coating; and since the coating process does not involve any heat, it preserves the base metals properties of superior formability, paintability and weldability.
