C-shaped steel frame is mainly used in high-rise steel structure in the process of processing. In order to improve its stability during operation, steel-concrete composite structure is usually used in operation. Its C-shaped steel bearing weight should be transferred to the structure by the most direct line. Different from the form of cylinder with outer frame in order to pursue economy.

In order to ensure the application of C-section steel in steel structure, the cutting of steel should be carried out on the shearing machine or sawing machine as far as possible, especially on the thin-walled steel roof truss, so as to ensure the precise cutting. This way can not only improve work efficiency, but also ensure quality. C-section steel of C-section steel has excellent performance and high strength.

C-section steel is mainly made by its cold-formed section steel, which can be connected into different combinations by using various accessories in operation. The appearance of C-section steel is beautiful, which can reduce the weight of building roof and reduce the amount of steel used in engineering. Therefore, it is called economical and efficient steel, and it is a new building material to replace the traditional steel purlin such as angle steel, channel steel and steel pipe. Mainly used in ground system or roof system. The installation site is an outdoor and roof platform with adjustable installation angle and maximum wind load of 60m/s.
