Product Description
HRB 500 Steel Rebar
Reinforcing steel refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including smooth round bars, ribbed bars, torsion bars. Rebar for reinforced concrete refers to straight or coil-shaped steel used for reinforced concrete reinforcement. Its shape is divided into two types: smooth round steel bar and deformed steel bar, and the delivery state is straight and coiled.
Classification of Rebars
There are many types of rebars, usually classified according to chemical composition, production process, rolling shape, supply form, diameter size, and use in structures:
1. According to the size of the diameter
Steel wire (diameter 3~5mm), thin rebar (diameter 6~10mm), thick rebar (diameter greater than 22mm).
2. According to mechanical properties
Grade Ⅰrebar (300/420 grade); Ⅱ grade rebar (335/455 grade); Ⅲ grade rebar (400/540) and Ⅳ grade rebar (500/630)
3. According to the production process
Hot-rolled, cold-rolled, cold-drawn rebars, as well as heat-treated rebars made of grade IV rebars, have higher strength than the former.
4. According to the function in the structure
Compression rebars, tension rebars, erection rebars, distributed rebars, stirrups, etc.
5. According to the rolling shape
①Smooth rebars: Grade I rebars (Q300 rebars) are all rolled into a smooth circular section, and the supply form is round, with a diameter not greater than 10mm and a length of 6m~12m.
② Ribbed rebars: There are three types: spiral, herringbone and crescent. Generally, grade II and III rebars are rolled into herringbone shapes, and grade IV rebars are rolled into spiral and crescent shapes. Crescent rib reinforcement: The longitudinal section of the transverse rib is crescent-shaped and does not intersect with the longitudinal rib.
③Steel wire (divided into low carbon steel wire and carbon steel wire) and steel strand.
④Cold-rolled and twisted rebars: after cold rolling and cold twisting.
Light round steel bars are actually small round bars and discs of ordinary low carbon steel. Deformed rebars are ribbed rebars on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse rib is spiral, herringbone and crescent. Expressed in millimeters of nominal diameter. The nominal diameter of a deformed rebar is equivalent to the nominal diameter of a light round steel bar of equal cross-section. The nominal diameter of the rebar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm. Steel types: 20MnSi, 20MnV, 25MnSi, BS20MnSi. rebars mainly bear tensile stress in concrete. Due to the effect of the ribs, the deformed rebar has a greater bonding capacity with the concrete, so it can better withstand the external force. Rebars are widely used in various building structures. Especially large, heavy, light thin-walled and high-rise building structures.
