Production Process	Rebar is a steel bar with ribbed surface, also known as ribbed reinforcement, usually with 2 longitudinal ribs and a transverse rib evenly distributed along the length direction. The shape of transverse rib is spiral shape,herringbone shape and crescent shape. In terms of millimeters of nominal diameter. The nominal diameter of ribbed reinforcement is equal to the nominal diameter of the light-round reinforcement with the same cross-section. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameter is 8, 12, 16, 20, 25, 32 and 40 mm.Ribbed bars mainly bear tensile stress in concrete. The ribbed steel bar can bear the action of external force better because of the effect of ribbed and concrete. Ribbed bars are widely used in various building structures, especially large, heavy, light thin-walled and tall buildings.

Reinforcing steel is a type of steel bar used in concrete construction. By adding these bars, you create reinforced concrete. Whether your project includes slabs, walls or columns, rebar helps prevent cracks from forming that would allow the project to crumble. While all concrete cracks, rebar and reinforcing materials help control the location and extent of cracks. It also provides structural strength to the project.

Carbon steel reinforcement is the backbone of concrete work. It is used in most concrete placements. This is because it is less costly and provides solid strength.
Glass fiber reinforced polymer GFRP is an alternative to traditional steel reinforcement. Using glass fibers, reinforcing bars are made into rods to provide reinforcement. It is stronger in terms of tensile strength.
Galvanized rebar is used in situations where corrosion may be a problem. Rebar is coated with zinc using several different processes. These include cold plating, hot plating or electroplating. The zinc provides a protective barrier on the steel.

Stainless steel rebar is used in corrosive environments where zinc cannot be used because of its galvanizing action. It tends to be more expensive than galvanized rebar. For this reason, it is only used when absolutely necessary.

Epoxy coated rebar is a modern and economical option for use in corrosive environments. Rebar is coated with epoxy resin to protect it from corrosion. However, it may not be the best choice in environments where substrate movement, cracks or mechanical movement could damage the protective coating, allowing corrosive materials to enter the steel.

European steel is measured in a different format than what we see in the US market. They still provide solid reinforcement for your concrete structure.

Rebar is a common type of hot rolled ribbed steel bar. The common hot-rolled rebar grade consists of HRB and the lowest yield point of that grade. h, R and B are the first letters of hot-rolled, ribbed and rebar, respectively.
Hot-rolled ribbed steel bars are divided into two grades HRB335 (old grade 20MnSi), three grades HRB400 (old grades 20MnSiV, 20MnSinB, 20MnTi) and four grades HRB500.

 

Advantages

Rebar is widely used in civil engineering construction such as buildings, bridges and roads. From highways, railroads, bridges, culverts, tunnels, flood control, DAMS and other public        facilities to the foundations, beams, columns, walls and slabs of housing buildings, rebar is an indispensable structural material. With the deepening of urbanization in China, the booming development of infrastructure construction and real estate, there is a strong demand for rebar.

Product Application

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.
