  • Hot dip galvanizing is a kind of external treatment technology in the production of fasteners. The common varieties of hot dip galvanizing fasteners are electric galvanizing, powder galvanizing, mechanical galvanizing and hot dip galvanizing. Wire factory according to different requirements of customers for fasteners, different hot-dip galvanized surface treatment. Galvanized layer and steel is a metallurgical connection, become a part of the steel surface, so the durability of the coating is more reliable.
