First of all, mechanical galvanizing is more convenient. In addition, when hot-dip galvanizing small parts such as gaskets, the parts are easy to stick together; when plating threaded parts, the molten zinc will block the threads; when plating nuts, they must be re-threaded after plating. Hot-dip galvanizing is an energy-consuming process that requires operation under high-temperature conditions and seriously pollutes the environment. High-temperature molten hot-dip galvanizing will affect the quality and performance of the plated parts. On the contrary, the mechanical galvanizing layer has the function of resisting atmospheric acid rain.
