Rebar is a rebar with a ribbed surface, also known as a ribbed bar, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse rib is spiral shape, herringbone shape, crescent shape 3. Expressed in millimeters of nominal diameter. The nominal diameter of a ribbed bar is equivalent to the nominal diameter of a circular bar with equal cross section. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameter is 8, 12, 16, 20, 25, 32, 40 mm

The hot metal billet is rolled into 6.5mm thick steel bar, that is, wire rod, and then put it into the wire drawing device to draw into different diameter lines, and gradually reduce the aperture of the wire drawing plate, cooling, annealing, coating and other processing technology to make a variety of different specifications of wire. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements

U-type steel is a widely used in steel structure of the construction of purlins, wall beams, can also be combined into lightweight roof truss, bracket and other building components, in addition, can also be used in mechanical light manufacturing columns, beams and arms. It is widely used in steel structure plant and steel structure engineering. It is a common construction steel. It is made by cold bending of hot coil plate. U-type steel has thin wall, light dead weight, excellent section performance and high strength. Compared with traditional channel steel, the same strength can save 30% of materials

Rebar is a surface ribbed bar, also known as ribbed steel, usually with 2 longitudinal ribs and evenly spaced horizontal ribs along its length. The shape of the cross-rib is spiral, herringbone and crescent-shaped. The nominal diameter is expressed in millimetres. The regular diameter of reinforcing bars are 8-50 mm and the recommended diameters are 8, 12, 16, 20, 25, 32 and 40 mm. Ribbed bars are mainly subjected to tensile stresses in concrete. Steel rebar has a greater bonding capacity with the concrete due to the ribs and is therefore better able to withstand the effects of external forces. It is used in a wide range of building structures, especially in large, heavy, light thin-walled and high-rise structures.
