Square and rectangular tubes are rolled from strip steel after processing. Generally, the strip steel is unpacked, flattened, curled, and welded into a round tube, which is then rolled into a square tube and then cut to the required length. It is widely used in machinery manufacturing, construction industry, metallurgical industry, agricultural vehicles, agricultural greenhouses, automobile industry, railways, highway guardrails, container frames, furniture, decoration and steel structure fields.

Round steel is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250 mm. Among them: small round steel of 5.5-25 mm is mostly supplied in straight strips and bundles, and is commonly used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used to manufacture mechanical parts and seamless steel pipe blanks. wait.

Prestressed steel strands are stranded steel cables composed of 2, 3, 7 or 19 high-strength steel wires that have been stress relieved (stabilized) and are suitable for prestressed concrete and similar purposes.
The main characteristics of prestressed steel strands are high strength and good relaxation performance, and they are relatively straight when unfolded. The common tensile strength grade is 1860 MPa, and there are also strength grades such as 1720, 1770, 1960, 2000, 2160, 2230, and 2360 MPa. The yield strength of this steel is also very high.
