Building steel can usually be divided into steel for steel structures and steel bars for reinforced concrete structures. The main types of steel used for steel structures are ordinary carbon structural steel and low alloy structural steel. There are types of steel, steel pipes, and steel bars. There are angle steel, I-beam steel, and channel steel in the section steel.


Steel bars for reinforced concrete structures can be divided into hot-rolled steel bars, heat-treated steel bars, cold-drawn steel bars, cold-drawn low-carbon steel wires, and steel strand pipes according to processing methods; According to surface shape, it can be divided into smooth steel bars and threads; According to the type of steel, it can be divided into low-carbon steel, medium carbon steel, high carbon steel, and alloy steel. Steel bars in China can be classified into five categories based on strength: I, II, III, IV, and V.
