Technical Parameter of Rebar

Reinforcing steel refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including smooth round bars, ribbed bars, torsion bars. Rebar for reinforced concrete refers to straight or coil-shaped steel used for reinforced concrete reinforcement. Its shape is divided into two types: smooth round steel bar and deformed steel bar, and the delivery state is straight and coiled.

The residual heat treatment steel bar is the finished steel bar obtained by piercing water immediately after hot rolling, conducting surface control cooling, and then using the residual heat of the core to complete the tempering treatment by itself. There are multiple grades of residual heat treatment steel bars. When welding is required, RRB400 weldable residual heat treatment steel bars should be selected.

  1. The total elongation δgt of the steel bar under the maximum force is not less than 2.5%. If the supplier can guarantee, the inspection may not be carried out.
  2. According to the requirements of the buyer, steel bars that meet the following conditions can be supplied:
  • a) The ratio of the measured tensile strength of the steel bar to the measured yield point is not less than 1.25;
  • b) The ratio of the measured yield point of the steel bar to the minimum yield point specified in the above table is not greater than 1.30.

Classification of Rebar

According to the diameter

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

According to mechanical propertiesb

Class I rebar (300/420); Class II rebar (335/455); Class III rebar (400/540) and Class IV (500/630)

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.

According to the role in the structure

Compression bars, tension bars, erecting bars, distribution bars, stirrups, etc.
