01. Galvanized
Electro-galvanizing is a common surface treatment method and process technology in the manufacture of fastener products.
02.Powder sherardizing
Powder zinc sherardizing is a surface treatment process in which zinc dipped zinc layer (zinc-iron alloy layer) is formed on the surface of steel by using zinc dipping agent as the source of zinc, and by heating to generate zinc and interdiffusion of iron atoms.
03. Mechanical galvanizing
Mechanical galvanizing is in the presence of zinc powder, dispersant, accelerator, liquid medium (usually water) and other substances, using impact media (such as glass balls) to impact and collide with the surface of steel parts, and form on the surface of the parts. Surface treatment process of galvanized layer.
04. Hot-dip galvanizing
Hot-dip galvanizing is also commonly referred to as hot-dip galvanizing.
Hot-dip galvanizing is a process and method in which pre-treated steel parts are put into a molten zinc solution to form a zinc and (or) zinc-iron alloy coating on the surface to obtain a metal coating.
