Corrugated / Arc Roof Sheet Forming
Corrugated and arc roof sheet line runs 18 forming stands (layers can run independently) with hydraulic shear and PLC-adjusted pitch - a classic, high-demand roofing profile worldwide.
What this process looks like
The bend angle is part of the build: the hydraulic shear cuts and bends in one station, with the angle set in the PLC. The two form layers can run independently, so confirm which path is live for your profile.

Operation steps
CAD board + bend limits
CAD board + bend limits
Load the customer CAD board and mark the agreed minimum and maximum bend angles before production starts.
5 T + paint-safe guide
5 T + paint-safe guide
Hand cutter and hand-wheel width adjustment at 1000/1250 mm without scratching the coating.
18-stand form
18-stand form
The profile forms across 18 stands; if only one layer runs, tag the live path on the board.
Shear with bend
Shear with bend
The hydraulic station cuts and bends in one action; the PLC sets the bend angle per the recipe.
Radius / angle gauge
Radius / angle gauge
Check the first panel against the template and the agreed bend angles before continuing.
Outfeed tables
Outfeed tables
Finished panels land on two 3 m tables, ready for bundling and site delivery.
What's included
This line
Corrugated/arc roof sheetformer with hydraulic shear+bend and optional dual-path stands — one host for flat and arc profiles.
Standard build
Hydraulic shear-with-bend, PLC angle set, paint-safe infeed guides, Siemens control and 3 m×2 outfeed tables.
Key details
Note 1
Unlike flat-only corrugated lines, this build includes post-cut bending for arc and curved profiles.
Note 2
The 18-stand host can run the upper or lower layer alone — confirm the active path for your profile.
