This roll forming machine is the special equipment for continuous rolling and cold-forming on steel sheet. It adopts coiling steel sheet as the raw material, decoiling, continuous rolling and cold-forming, automatically cut to the size and specification which required, and stacking the finishing panel automatically. The equipment adopts PLC control, AC frequency and adjusting the speed technology, and it realize the continuous automatically production, therefore, it is really a new type of energy-saving and high-effective producing equipment for steel structure
