U-bolts are bolts that look like a U-shape. U-shaped bolts may seem simple, but their manufacturing process is a major subject. According to the galvanizing method and the different requirements of customers, the commonly used galvanizing processes for U-shaped bolts include electro-galvanizing, powder galvanizing, mechanical galvanizing, and hot-dip galvanizing.
01.Electro-galvanized
Electro-galvanizing is a common surface treatment method and process technology in the production and manufacturing of fastener products.
02.Powder zinc infiltration
Powder zincizing is a surface treatment process that uses a zinc dipping agent as a zinc source, generates zinc through heating, and interdiffusions of iron atoms to form a zinc dipping layer (zinc-iron alloy layer) on the surface of the steel.
03. Mechanical galvanizing
Mechanical galvanizing uses impact media (such as glass balls) to impact and collide with the surface of steel parts in the presence of zinc powder, dispersants, accelerators, liquid media (usually water) and other substances. Surface treatment process of galvanized layer.
04.Hot dip galvanizing
Hot dip galvanizing is also commonly called hot dip galvanizing.
Hot-dip galvanizing is a process and method in which pre-treated steel parts are put into molten zinc liquid to form a zinc and/or zinc-iron alloy coating on the surface to obtain a metal coating.
