steel rebar 6mm/9mm/12mm deformed steel rebar iron bar steel rebar for construction HRB400
Steel rebar introduction:
Rebar (Reinforcing Bar) is a ferrous steel deformed bar which is used for reinforcement, strengthening & holding concrete. It is usually formed with a surface which is patterned (known as a deformed bar) to make a better adherence with the concrete spilled around it. No specific or special patterns are there for deforming, however, the number, spacing, and the height of the marks are standardized and integrated into the primary debar. In addition, there are plain bars which are used in the most specific and
definite ways, only.Owing to the fact that rebar holds the concrete in a compact state, it is known as a tensioning material. when it comes into the compression, concrete is a very tough and strong material, but it almost has no strength where it comes to carrying tensile loads. To overcome this, rebar casts in concrete to carry the loads.

Steel rebar application:
Steel rebar is widely used in civil engineering construction such as houses, bridges, and roads. From highways, railways, bridges, culverts, tunnels, flood control, dams and other public facilities, to the foundations, beams, columns, walls, and slabs of building structures, threaded steel is an indispensable structural material.
