Galvanized Round Bar
Galvanized Round Bar
Galvanized round bar is a type of steel round bar primarily made from A36 carbon steel. It undergoes a hot-dip galvanizing process, which creates a uniform and smooth zinc coating on its surface. This coating offers high resistance to rust, making it ideal for use in tough environments like humid, rainy, coastal, or industrial areas, thereby greatly extending its service life.
The round bar can be used as shafts, pins, bolts, rivets, mechanical parts, and in building structures, making it highly suitable for industries such as machinery manufacturing, automotive, construction, and hardware.

Manufacturing Process
- Steel Round Bar Production: Steel billets or ingots are heated and shaped into round bars of different diameters through a hot rolling process.
- Hot-Dip Galvanization: The newly formed round bars are thoroughly cleaned (degreased, pickled, rinsed, fluxed) and then dipped in molten zinc to apply a protective, corrosion-resistant coating.
