Rebars (also known as Deformed Steel Bar) refers to steel for reinforced concrete and prestressed reinforced concrete with a circular cross-section and sometimes a square with rounded corners. Including smooth round bar, ribbed bar, 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.
The smooth round steel bar is actually the small round steel and coil of ordinary low carbon steel. Deformed bars are surface-ribbed bars, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse rib is spiral, herringbone and crescent shape. Expressed in millimeters of nominal diameter. The nominal diameter of deformed bars corresponds to the nominal diameter of smooth round bars 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, and 40 mm. Steel grades: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Reinforcing bars are mainly subjected to tensile stress in concrete. Due to the action of ribs, deformed steel bars have greater bonding ability with concrete, so they can better withstand the action of external forces. Steel bars are widely used in various building structures. Especially large, heavy, light thin-walled and high-rise building structures.

There are many types of rebar, usually classified by chemical composition, production process, rolling shape, supply form, diameter size, and use in the structure:
1. According to the diameter
Steel wire (diameter 3~5mm), thin steel bar (diameter 6~10mm), thick steel bar (diameter greater than 22mm).
2. According to the mechanical properties
Class I rebar (300/420); Class II rebar (335/455); Class III rebar (400/540) and Class IV (500/630)
3. According to the production process
Hot-rolled, cold-rolled, cold-drawn steel bars, as well as heat-treated steel bars made of grade IV steel bars, have higher strength than the former.
Rebar processing generally goes through four processes:
rebar rust removal➜ rebar straightening➜ rebar cutting➜ rebar forming.
Currently, reinforced concrete is used in civil, industrial and high-rise buildings. They are the main materials that determine
the bearing capacity of the building. There is currently no concrete type that can replace reinforced concrete. It is used in most
of the existing construction works today. In particular, reinforced concrete promotes its advantages in large projects that need
high bearing capacity. High-rise buildings, industrial buildings, airports, bridges, roads, etc. all use reinforced concrete.
