Light round steel bars are actually small round bars and discs of ordinary low carbon steel.
Deformed bars are ribbed bars on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse rib is spiral, herringbone and crescent. The nominal diameter of a deformed steel bar is equivalent to the nominal diameter of a light 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. Steel types: 20MnSi, 20MnV, 25MnSi, BS20MnSi.

2) The total elongation δgt of the steel bar under the maximum force is not less than 2.5%. If the supplier can guarantee it, no inspection is required.
3) 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.
