Steel production process

Rebar surface ribbed steel, also known as ribbed, usually with 2 longitudinal ribs and evenly distributed along the length of the transverse ribs. Transverse rib shape of spiral-shaped, Gable, Crescent-shaped 3. Expressed as the number of nominal diameter mm. Ribbed plain round bar equal to nominal diameter equal to the cross section of the nominal diameter. Bar nominal diameter 8-50 mm, recommended diameters of 8, 12, 16, 20, 25, 32, 40 mm. Main rebar in concrete under tensile stress. Ribbed because of rib, and concrete has a greater capacity, and thus can better withstand a force is exerted. Ribbed steel is widely used in various structures, especially large, heavy, light thin-wall and high-rise building.
