Product Description

Low Carbon round steel round bar, round steel billet , Steel square bar. Hex bar.
Steel bar is a long strip of steel with a solid cross section. They are divided into three types:
Hot-rolled, forged, and cold-drawn.
The hot-rolled specifications are 5.5-250 mm. They are often used as steel bars, bolts,
and various Mechanical parts,round steel larger than 25 mm is mainly used to manufacture
mechanical parts and seamless steel tube billets.
