It can be used as the main force-bearing structure of large and medium-sized industrial civil buildings. C-shaped steel machine is a set of single-roll forming unit whose roll can produce various specifications of C-shaped purlin finished products. This machine is mainly composed of passive loading rack, leveling device, punching device, cutting device after forming, hydraulic station, computer control system, etc. The finished C-shaped steel rolled by the C-shaped steel machine has good tensile and bending performance, good flatness, automatic fixed-length cutting, automatic punching, high degree of automation, fast and convenient installation, and the product can be used as the main body of large and medium-sized industrial civil buildings. Force structures, such as roof load-bearing load and flat wall support of factory buildings, warehouses, hangars, hangars, exhibition halls,

theaters, stadiums, and market sheds.

The production process includes uncoiling-feeding-rolling forming-calibration-shearing-receiving. It can realize fully automated roll forming and change models to meet the needs of reducing labor costs and diversifying products.
