Q:What is the classification standard of rebar?

There are two commonly used classification methods for rebar: one is classified by geometric shape, and it is classified or typed according to the cross-sectional shape of the transverse rib and the distance between the ribs. For example, in the British Standard (BS4449), the rebar is divided into type I, Type II. This classification mainly reflects the grip performance of rebar. Another is based on its performance to classify (level). For example, China's current implementation standard, the rebar is divided into 3 types according to the strength level (such as yield point, tensile strength, etc.). In the Japanese Industrial Standard (JISG3112), the rebar is divided into 5 categories according to the comprehensive performance. In addition, the rebar can be classified according to the purpose, such as: ordinary steel bars for reinforced concrete, prestressed steel bars, heat-treated steel bars for concrete, etc.
