Cold forming selectional steel is a structural steel that shaped by one that has sections containing a variety of shapes and sizes by brake forming with hot rolling and cold-strip steel. Cold forming selectional steel owns the following characteristics:
1. Reasonable sections economy and saveing in materials. The shapes of sections of cold forming selectional steel can be designed as needed. Its structure and section factor of unit weight are higher than hot forming selectional steel. Under the same load, it can reduce the structural weight and save the materials. When used in building structure, it can save more metal than hot forming selectional steel from 38% to 50%; when used for agricultural machinery and cars, it can save 15% to 60% metal. It has the advantage of easy construction and lower the overall cost.
2.It has various of types which can produce the cold forming selectional steel that has uniform wall thickness and complicated shapes of sections and different materials ones. All that are difficult to realize when using hot rolling method.2.It has various of types which can produce the cold forming selectional steel that has uniform wall thickness and complicated shapes of sections and different materials ones.

3. The surface of product is bright and clean. Its appearance is nice and size is accurate. Moreover, its length can be adjusted when needed. All are supplied with fixed scale or scale with times, which increase the availability of materials.
4. The production can also be matched with the punch and other processes to meet different needs. 4. During the production, it can also be matched with procedures like punching to meet different requirements.
