Screw steel is a steel bar with ribs on the surface, also known as ribbed bars, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the longitudinal direction. The transverse rib shape is helical, herringbone, crescent 3. Nominal diameter of mm. Nominal diameter equal to the nominal diameter of the circular steel bars of equal cross section. The nominal diameter of the steel bar is 8-50 mm. The recommended diameter is 8, 12, 16, 20, 25, 32, 40 mm. Tensile stress in concrete with ribbed steel bars. Ribbed steel bar because of the role of ribs, and concrete have a larger bond capacity, and thus can better withstand the role of external forces. Ribbed steel bars are widely used in various building structures, especially large, heavy, light, thin wall and high rise building structures.

Thread steel is widely used in building, bridge, road and other civil engineering construction. Highways, railways, bridges, culverts, tunnels, flood control, dam etc. utilities to large, the small building foundation, beams, columns, a wall, a slab, rebar is indispensable structural materials.

This is the mechanical properties of thread steel grade and size specifications of the method.

H, R, B are hot rolling (Hotrolled), ribbed (Ribbed), steel (Bars) three words of the first letter in english.

HRB behind the figures, said its production level for the mechanical properties of materials, specific value is the material yield strength sigma S (sigma 91). Such as:

HRB335, which indicates that the yield strength is 335MPa of the rebar.
