HRB400 HRB500 Steel Rebars

HRB steel bars, that is, Hot-rolled Ribbed Bar, hot-rolled ribbed bars, the so-called ribbed steel bar refers to the surface of the steel bar that is deformed by hot rolling process to increase the occlusal force with concrete, including surface ribbed steel bar, spiral bar , Herringbone bar, crescent bar, etc.
Rebar is a common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bar consists of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words, Hotrolled, Ribbed, and Bars, respectively.
The hot-rolled ribbed steel bar is divided into three grades: HRB335 (the old grade is 20MnSi), grade three HRB400 (the old grade is 20MnSiV, 20MnSiNb, 20Mnti), and grade four HRB500.

There are many types of rebar, usually classified by chemical composition, production process, rolling shape, supply form, diameter size, and use in the structure:
1. According to the diameter
Steel wire (diameter 3~5mm), thin steel bar (diameter 6~10mm), thick steel bar (diameter greater than 22mm).
2. According to the mechanical properties
Class I rebar (300/420); Class II rebar (335/455); Class III rebar (400/540) and Class IV (500/630)
3. According to the production process
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.

Rebar processing generally goes through four processes: 

rebar rust removal➜ rebar straightening➜ rebar cutting➜ rebar forming.

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.
