Roof Sheet Making Machine - Trapezoidal Metal Roofing Line

Front view of the cutting end of the roof sheet making machine: a white crossbeam carries a metallic zigzag rib shear blade driven by two red hydraulic cylinders, with a grey motor and high-pressure hoses above and a red emergency stop at the column base. A partially formed steel profile waits behind the cutter, and the XINNUO MACHINE nameplate on the crossbeam marks the factory-built unit.

Close-up of the forming section of the roof sheet making machine: precision-polished silver rollers press the sheet into shape while a heavy dark drive chain runs through the frame center, with silver bolts and white spacer blocks for tuning pressure and alignment. A blue trapezoidal box-rib sheet is actively passing through the machine, its sharp angular ribs matching the frame color - the profile taking shape before the hydraulic cut.

Close-up of the hydraulic power station of the roof sheet making machine: a royal-blue reservoir topped by a vertical grey motor with cooling fins, paired with a bright orange air-cooled oil cooler with a circular fan grille and a silver knurled fill cap on the tank. The 380V label on the cooler and the corrugated conduits show a clean, standard electrical and cooling setup for continuous forming duty.

High-angle close-up inside the roller assembly of the roof sheet making machine: silver forming rollers on parallel shafts mix flat disks with concave wavy profiles that shape the sheet ribs, while heavy-duty chains and sprockets synchronize every shaft and long polished guide rods run across the top to steer the sheet. The bright blue side plates house the bearings that keep this forming core precise under load.

Loading scene of the roof sheet making machine: the bright blue two-level roll former with orange safety guards is hoisted by an overhead crane toward MAERSK containers, while stacks of plastic-wrapped profiled steel sheets rest on the frame top. The integrated hydraulic cutting unit at the frame end confirms the machine ships as one complete, ready-to-run production line.

Roof Sheet Making Machine - Built by XINNUO Since 1995

XINNUO has manufactured cold roll forming equipment since 1995, with more than 30 years of continuous production practice. Single-layer roof sheet making machines are our largest product line, backed by hundreds of production-proven profiles spanning effective widths from 600mm to 1200mm and 3 to 12 peaks.

Our roof sheet making machines are available in standard, heavy-duty, high-speed and archway tiers, with options including A-wheel edge lip forming for weather sealing, inline arching mechanisms for curved roofs, and two-level configurations that produce two different profiles on one machine. Each machine is engineered with hardened steel rollers, heavy drive chains, hydraulic cutting and PLC control, then assembled and test-run in our own workshop.

We have delivered roll forming equipment to more than 150 countries across Europe, the Middle East, Africa, Southeast Asia and the Americas, with installation guidance, operator training and dependable after-sales support.

FAQ

Q1: What is a roof sheet making machine?

A: A roof sheet making machine feeds a steel coil through precision forming rollers to produce trapezoidal or corrugated roof and wall sheets, cutting them to length with a hydraulic shear.

Q2: Which profiles can this machine produce?

A: Common profiles include 840mm, 900mm, 1000mm and 1050mm trapezoidal sheets with 3 to 12 peaks, plus corrugated profiles. Roller sets can be engineered for your drawings and local market preferences.

Q3: How does the cutting system work?

A: A hydraulic shear with a zigzag rib blade cuts each sheet to preset lengths under PLC control, giving accurate, burr-free edges without slowing the forming line.

Q4: What power supply does the machine need?

A: Standard configurations run on 380V/50Hz or 220V/60Hz. Please confirm your local voltage and phase when requesting a quotation.

Q5: Can one machine produce two different profiles?

A: Yes. A two-level machine carries two roller sets on one frame, so you can switch between two profiles without changing tooling - ideal for workshops serving several profile markets.

Q6: Can it form trapezoidal and wavy corrugated sheets?

A: Yes. Interchanging the roller sets changes the profile; the forming core, drive chain and cutting unit remain the same.

Q7: What material can it process?

A: Color-coated and galvanized steel coils in common roofing gauges. Send us your material thickness and coil width, and we will confirm the roller and drive configuration.

Q8: How do I get a quotation?

A: Send your profile drawing or sample, material spec and daily output target via WhatsApp/Wechat +86 188 0307 8605 or email sara@xinnuomachine.com. We reply within 24 hours.
