Roofing Sheet Manufacturing Machine - Cold Roll Forming Equipment

Front view of the discharge end of the roofing sheet manufacturing machine: the roller frame with a large top motor and side drive chains carries a hydraulic cutting device with red cylinders and a zigzag trapezoidal shear blade, while the white control box with emergency-stop indicator and handheld remote sits at the front. A finished trapezoidal panel sample is passing through the upper roller level, and the XINNUO MACHINE nameplate identifies the line.

Extreme close-up of the hydraulic press assembly of the roofing sheet manufacturing machine: a thick bright red cylinder is clamped between matte black plates by four long gold threaded bolts with silver acorn nuts, the mounting hardware that transfers cutting force without loosening under repeated strokes. The blue frame around it keeps the whole pressing unit rigid for clean, consistent cuts.

Close-up of the hydraulic circuit of the roofing sheet manufacturing machine: the red cylinder connects through silver piping with a brass T-junction fitting and hex nuts to a high-pressure hose carrying a red-and-white rating label, while tiered conical forming rollers in the mid-ground progressively bend the sheet between the blue side plates. The sharp focus on the fittings shows the quality of the pressure system.

Full-length perspective of the roofing sheet manufacturing machine from the entry end: the black flat-bed entry table with two red-handled adjustable guides centers the incoming sheet into the first forming station, and row after row of polished steel roller stations runs along the blue side plates toward the exit. Heavy-duty drive chains along the left frame and the blue motor-gearbox unit at the rear drive the whole forming section.

Export loading scene of the roofing sheet manufacturing machine: blue machine modules with hydraulic pump station, control cabinet and built-in post-cutting shear are lowered by an overhead crane onto a flatbed truck and guided into MAERSK containers with a forklift. The four-panel view documents the whole packing process, confirming each module ships protected and ready for fast on-site assembly.

Roofing Sheet Manufacturing Machine - Built by XINNUO Since 1995

XINNUO has been building cold roll forming equipment since 1995, with more than three decades of production experience. Roofing sheet manufacturing machines form our core export line, backed by hundreds of production-proven trapezoidal and corrugated profiles from 600mm to 1200mm effective width and 3 to 12 peaks.

Our machines are offered as single or double-layer configurations - the double-layer frame carries two roller sets so one machine produces two profiles without tooling change. Standard equipment includes hardened steel roller dies, heavy drive chains, a hydraulic post-cutting shear with profile-matched zigzag blade and PLC length control. Modules are assembled, test-run and container-packed in our own workshop.

We have exported roll forming equipment to more than 150 countries, with installation guidance, operator training and dependable after-sales support throughout the machine's service life.

FAQ

Q1: What does a roofing sheet manufacturing machine do?

A: It feeds a steel coil through precision forming rollers to produce trapezoidal or corrugated roofing sheets, cuts them to length with a hydraulic post-cutting shear and discharges them on an outfeed table.

Q2: What is a double-layer roofing machine?

A: A double-layer machine carries two roller sets on one frame, so you can produce two different profiles on the same machine by switching the material path - no tooling change, no second machine.

Q3: How does the hydraulic cutting work?

A: The hydraulic post-cutting shear uses a zigzag blade matched to the sheet profile, driven by hydraulic cylinders and controlled by the PLC for accurate, burr-free lengths.

Q4: How is the sheet aligned at the entry?

A: An entry table with two adjustable guides centers the incoming coil sheet into the first forming station, keeping the profile straight from the very first pass.

Q5: What hydraulic system does the machine use?

A: A hydraulic pump station feeds the cylinders through high-pressure piping with T-junction fittings; the oil cooler and rated hoses keep the system stable under continuous cutting duty.

Q6: Which profiles can this machine produce?

A: Common trapezoidal profiles include 840mm, 900mm, 1000mm and 1050mm sheets with 3 to 12 peaks, plus corrugated profiles; roller sets are engineered for your drawings.

Q7: How is the machine shipped?

A: The machine is module-assembled, test-run and container-packed in our workshop, with lifting and packing documented; a guide team supports on-site assembly and commissioning.

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.
