Cold-formed steel is steel with various cross-sectional shapes and sizes made by bending hot-rolled or cold-rolled strip steel as a blank. Cold-formed steel has the following characteristics: 

1. The cross section is economical and reasonable, saving materials. The cross-sectional shape of cold-formed steel can be designed according to needs, the structure is reasonable, and the section coefficient per unit weight is higher than that of hot-rolled steel. Under the same load, the weight of components can be reduced and materials saved. Cold-formed steel can save 38-50% of metal when used in building structures compared to hot-rolled steel and can save 15-60% of metal when used in agricultural machinery and vehicles. Convenient construction and reduced comprehensive costs. 

2. There are many varieties, and it can produce various profiles with uniform wall thickness and complex cross-sectional shapes that are difficult to produce by ordinary hot rolling methods, as well as cold-formed steel of various materials. 

3. The product has a smooth surface, good appearance, and accurate dimensions, and the length can be flexibly adjusted as needed. All products are supplied in fixed lengths or multiple lengths to improve material utilization. 

4. It can also be matched with punching and other processes during production to meet different needs.
