Cold-formed section steel is made of hot-rolled or cold-rolled strip by bending. Cold-formed steel has the following characteristics:
1. The section is economical and reasonable, and material is saved. The cross-section shape of cold-formed section steel can be designed according to the need, and the structure is reasonable. The cross-section coefficient per unit weight is higher than that of hot-rolled section steel. Under the same load, the weight of the component can be reduced and the material can be saved. The cold-formed section steel can save 38-50% of the metal in building structure and 15-60% of the metal in agricultural machinery and vehicles compared with hot-rolled section steel. It is convenient for construction and reduces the comprehensive cost.
2. Various kinds of profiles and cold-formed profiles of various materials with uniform wall thickness and complex cross-section can be produced by common hot rolling method.
3. The surface of the product is clean, the appearance is good, the size is accurate, and the length can also be adjusted flexibly according to the need, all of them are supplied according to fixed or multiple rulers, so as to improve the utilization rate of materials.
4. Production can also be combined with punching and other processes to meet different needs.
