Here’s a fast, informative look at what this solution does and how it behaves. In this video, we showcase NKH Machinery's Column Roll Forming Machine in action, demonstrating how it produces high-strength interlocking box column profiles from galvanized steel. You'll see the complete automated process—from uncoiling and leveling the steel strip, through precision punching and roll forming, to final hydraulic cutting—all controlled by a Siemens PLC system. Discover how this integrated production line creates durable, corrosion-resistant structural columns ideal for industrial frames, warehouse shelving, and solar mounting structures.
