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
Grade I steel bars (Grade 300/420); Grade II steel bars (Grade 335/455); Grade III steel bars (400/540) and Grade IV steel bars (500/630)
3. According to production technology
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.
4. According to the role in the structure
Compression steel bars, tension steel bars, erecting steel bars, distributed steel bars, stirrups, etc.

Product Display
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.
