Polished round bar is a metal material processed from ordinary round steel or ground round bar through mechanical polishing (such as cloth wheel polishing, grinding wheel polishing) orchemical polishing techniques. Its core feature is an extremely high surface finish, capable of achieving a mirror-like effect (with a surface roughness of Ra ≤ 0.2μm).

it can effectively remove fine scratches, oxide scales, and processing marks on the surface of the base material while retaining the mechanical strength and dimensional accuracy of the round steel itself.

For some high-end products, the diameter tolerance can be controlled within ±0.01mm. In application scenarios, relying on its excellent surface aesthetics and corrosion resistance,

polished round steel is widely used in the decoration field (such as furniture accessories, architectural decorative parts), precision instruments (such as medical device housings, instrument drive shafts),

and food machinery field. For example, the transmission shafts in food processing equipment adopt polished round steel, which can not only prevent medium residue but also reduce bacterial growth;

while polished round steel for decoration enhances the overall texture of products through its mirror-like effect, making it suitable for high-end decoration or industrial products with high appearance requirements.
