Reinforcing Concrete Deformed Steel Rebar

Reinforcing Concrete Deformed Rebar refers to steel for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners. Including plain round steel bars, ribbed steel bars, and torsion steel bars.
Steel bars for reinforced concrete refer to straight or coiled steel bars used for reinforcing reinforced concrete. Their shapes are divided into two types: plain round steel bars and deformed steel bars. The delivery state is straight bars and coiled bars.

Features of Reinforcing Concrete Deformed Steel Rebar

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

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

Classification of steel bars:

There are many types of steel bars, which are usually classified according to chemical composition, production process, rolling shape, supply form, diameter size, and use in structures:

1. According to diameter

Steel wire (diameter 3~5mm), thin steel bar (diameter 6~10mm), thick steel bar (diameter greater than 22m)

2. According to mechanical properties

The steel bars configured in reinforced concrete structures can be divided into the following types according to their functions:

1. Stress-bearing bars - steel bars that bear tensile and compressive stress.

2. Stirrups - bear part of the diagonal tension stress and fix the position of the stress-bearing bars. They are mostly used in beams and columns.

3. Erecting bars - used to fix the position of the steel hoops in the beam and form the steel frame inside the beam.

4. Distributed ribs - used in roof panels and floor slabs, arranged vertically with the stress-bearing ribs of the slab, to evenly transfer the weight to the stress-bearing ribs, fix the position of the stress-bearing ribs, and resist thermal expansion and contraction. temperature deformation.

5. Others - structural reinforcements configured due to component structure requirements or construction and installation needs. Such as waist bars, embedded anchor bars, prestressed bars, rings, etc.
