What are the surface treatment processes of U-bolts?

Four surface manufacturing processes of U-bolts

U-bolts are U-shaped bolts. U-bolts seem to be simple, but their production process is a big question. According to the galvanizing method and the different requirements of customers, the commonly used galvanizing processes for U-bolts are electrogalvanizing, powder galvanizing, mechanical galvanizing, and hot-dip galvanizing.

01. plating galvanized

Electrogalvanizing is a common surface treatment method and process technology in the manufacture of fastener products.

02. Powder sherardization

Powder galvanizing is a surface treatment process in which a zinc immersion agent is used as a source of zinc, and zinc is generated by heating, and iron atoms diffuse into each other to form a galvanized layer (zinc-iron alloy layer) on the surface of steel.

03. Mechanical galvanizing

Mechanical galvanizing is the use of impact media (such as glass balls) in the presence of zinc powder, dispersants, accelerators, liquid media (usually water) and other substances to impact 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 a process and method for adding pre-treated steel parts into molten zinc solution to form zinc and/or zinc-iron alloy coatings on their surfaces, thereby obtaining a metal coating.
