Dual 11KW motor cold roll forming line for steel deck
26-30 station progressive forming with PLC auto control
Dimple embossment roller set for concrete bond grip
Hydraulic dual-cylinder floor shear, gravity panel stack
This floor decking machine is a continuous cold roll forming production line engineered to convert galvanized steel coil into structural trapezoidal floor deck panels — the permanent steel formwork used in composite concrete floor slab construction. Each panel carries wet concrete loads during the construction phase and bonds with the cured slab to act as tensile reinforcement, eliminating the need for timber shuttering and reducing overall structural steel by up to 30%. Designed for 24-hour continuous operation in high-volume decking manufacturing plants.
