Hot Rolled Steel Rebar Iron Deformed Steel Bar Rod For Building
Construction
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 Features:
Rebar is a steel bar with ribs on the surface, also known as ribbed
steel bar, usually with 2 longitudinal ribs and transverse
ribs evenly distributed along the length direction The nominal diameter of a ribbed steel bar is equivalent to the
nominal diameter of a smooth round steel bar of equal cross-section. The nominal diameter of the steel bar is 8-50 mm,
and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm.
Ribbed steel bars are mainly subjected to tensile stress in
concrete
Steel Rebar Application:
Rebar is widely used in civil engineering construction such as
houses, bridges and roads. As large as public facilities such as
highways, railways, bridges, culverts, tunnels, flood control,
dams, etc., as small as foundations, beams, columns, walls, and
panels of house construction, rebar is an indispensable structural
material
