High Strength Microalloyed Steel Bar

The light round steel bar is actually a small round steel and disk circle of ordinary mild steel. Deformed bars are bars with ribbed surfaces, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse rib is spiral shape, herringbone shape and crescent shape. Expressed in millimeters of nominal diameter. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm.
