Two Layer Widths 30mm Apart: Layer widths of 1020mm and 1050mm keep coil setting and changeover close.
18 Stations Per Layer: Trapezoidal ribs build progressively, holding the sheet flat along the run.
400H Frame: A heavy frame suits factories running wide trapezoidal sheets day after day.
Pure Cold Forming: No pitch pressing stage, so there are fewer wear points to service.
Twin Coil Widths: 1220mm and 1250mm strip are both covered by the same line.
One Layer At A Time: Either profile runs on demand, with changeover taking a few minutes.
Set From Panel: Finished length and batch count are entered on the control panel.
Drawing Matched: Layer widths, rib height and rib pitch follow the profile drawings you supply.

Close Layer Widths: Only 30mm between the two profiles, so the coil setting barely changes between runs.
Matched Station Count: 18 stations on each layer keeps forming quality even across both profiles.
Heavy Frame: A 400H frame and 75mm shafts hold the section on long production runs.
Simple Design: Pure cold forming with no pitch pressing stage means fewer wear points.
Fewer Operations: Forming, sizing and cutting run as one line.
Twin Widths Covered: 1220mm and 1250mm strip both run on the same machine.
Low Waste: Offcut stays modest across both layer widths.
