Roof Sheet Roll Forming Machine - Trapezoidal Metal Sheet Line

Front view of the cutting head of the roof sheet roll forming machine: a heavy zigzag corrugated shear blade secured by dark bolts sits between two silver vertical guide rods, driven by two orange cylinders and a grey motor on the blue frame, while the tall sensor column with red indicator light monitors the cut. The XINNUO MACHINE and Cold Roll Forming nameplate on the top beam identifies the line.

Close-up of the roof sheet roll forming machine in operation: a bright blue corrugated sheet is held by white-and-blue guide brackets as it passes over polished hourglass-shaped rollers that form the ribs, with a heavy drive chain running across the frame on sprockets to turn every shaft. The tapered roller profiles and bracket alignment keep the trapezoidal shape consistent sheet after sheet.

High-angle view along the roller bank of the roof sheet roll forming machine: parallel steel shafts carry rows of polished chrome hourglass rollers that gradually bend the sheet into profile, with two thin guide rods above directing the material and black sprockets on the shaft ends driven by heavy double-strand chains. Hand-stamped numbers on the roller faces, including 88 and 9.5, mark the calibrated roller set.

Overhead close-up of the adjustment system of the roof sheet roll forming machine: a flat black adjustment plate with long slots and two bright red L-shaped locking handles repositions the guides, while the manual lever with a textured black handle and the polished guide rails set the forming width precisely. Smooth cylindrical rollers with deep grooves sit above, ready for the next profile changeover.

Close-up of the hydraulic shearing section of the roof sheet roll forming machine: grey die plates with a notched zigzag profile are clamped by black bolts between polished chrome guide rods that steer the vertical press motion, with a large cream hydraulic cylinder housing one rod and brass fittings on its side. The nameplate on the upper beam and the yellow safety line mark the cutting station of the line.

Export packing scene of the roof sheet roll forming machine: the blue multi-level machine wrapped in protective plastic film is lowered by an overhead crane into an open-top container on a yellow flatbed truck, supported by a red forklift, and guided into a grey MAERSK container. The four-panel collage documents the careful lifting and packing of every module for safe overseas delivery.

Roof Sheet Roll Forming Machine - Built by XINNUO Since 1995

XINNUO has been in the cold roll forming business since 1995, and our roof sheet roll forming machines are among the most widely exported lines in our range. With hundreds of production-proven trapezoidal and corrugated profiles from 600mm to 1200mm effective width and 3 to 12 peaks, we cover the full spectrum of metal roofing production.

Each machine is built around hourglass-shaped forming rollers that bend the sheet progressively, driven by heavy double-strand chains and sprockets for synchronized rotation, and finished with a zigzag hydraulic shear under PLC length control. An adjustable guide platform and calibrated roller sets make profile changeovers quick and repeatable. Every line is assembled, test-run and container-packed in our own workshop before shipment.

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

FAQ

Q1: What is a roof sheet roll forming machine?

A: It is a roll forming line that feeds a steel coil through hourglass-shaped forming rollers to produce trapezoidal or corrugated roofing sheets, cutting them to length with a zigzag hydraulic shear.

Q2: Why are hourglass-shaped rollers used?

A: The hourglass (double-conical) profile bends the sheet progressively through each station, distributing the forming force evenly and producing consistent rib shapes without marking the coating.

Q3: How does the machine change between profiles?

A: An adjustable guide platform with locking handles, plus calibrated roller sets, allows quick profile and width changeovers - typically a straightforward roller swap on the same frame.

Q4: What drives the forming rollers?

A: A motor and gearbox turn the shafts through heavy double-strand chains and sprockets, keeping every roller station synchronized so the sheet forms uniformly along the whole line.

Q5: How does the cutting system stay accurate?

A: The zigzag shear blade is guided by vertical chrome rods and synchronized with the forming speed by the PLC, so every sheet is cut to the preset length with clean edges.

Q6: What material can it process?

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

Q7: How is the machine packed for shipping?

A: Each module is wrapped in protective film, lifted by crane and loaded into MAERSK containers with documented packing; our engineers support 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.
