Adjustable C150-C200-C250-C300 Light Gauge Steel Roll Forming Machine for Floor Deck

Yes - the width is adjusted via a motorized ball screw system controlled through the touchscreen. You simply select the target profile (C150, C200, C250, or C300) on the HMI, and the forming stations reposition automatically. The rollers themselves accommodate the shared lip height (41 mm) across all four profiles. No roller or die changes are required. This is a genuine 4-in-1 machine, not a manual-changeover setup.

GCr15 is a bearing steel (good for wear resistance at moderate loads), whereas Cr12MoV is a cold-work die steel designed for high-contact-pressure metal forming. When processing G550 structural steel at 2.5 mm thickness, the compressive stress on the roller surface far exceeds what GCr15 can sustain long-term. Cr12MoV at HRC 58-62 delivers 3-5 times longer service life under these conditions, which translates directly to lower roller replacement costs and fewer production stoppages.

Absolutely. The machine is optimized for G550 (tensile strength ~550 MPa), but it handles the full range from Q235 (235 MPa) through Q345 (345 MPa) and G450. The 15 kW servo motor provides ample torque headroom across all grades. The key constraint is thickness -stay within the machine's range (0.75-1.6 mm for the narrower profiles, 1.2-2.5 mm for C250/C300). Thinner Q235 will actually run faster and place less load on the drivetrain.

Based on 20 m/min maximum speed, theoretical output is 1,200 meters per hour or 9,600 meters per 8-hour shift. In practice, accounting for coil changes, profile adjustments, and punching complexity, expect 7,000-8,500 meters per shift. At 2.5 mm G550 thickness for C300 profiles, this equates to roughly 12-15 tons per shift. For C150 at 0.75 mm, material throughput is lower by weight but faster by meter. We recommend budgeting for 6,000-8,000 meters per shift in your production planning.

A full profile changeover between the two extremes (C150 - C300) typically takes 15-20 minutes and requires two operators. The process: (1) release locking nuts on the adjustment rail, (2) input C300 on the touchscreen to drive the encoder-controlled motorized adjustment, (3) re-tighten and verify alignment with a test strip. You must stop the line during changeover. Switching between adjacent sizes (e.g., C200 - C250) is typically 8-10 minutes. The encoder memory stores your last-used positions
