840+900 Double Layer Roof Panel Machine | Trapezoidal Line

Hebei Xinnuo Roll Forming Machinery Co., Ltd. (XINNUO) has built cold roll forming equipment for more than 30 years in Botou, Hebei, China, with an annual output of over 3,000 sets and exports to more than 140 countries and regions. The 840+900 double layer roof panel machine is one of our most frequently ordered dual-profile lines: two complete forming systems are stacked vertically in a single machine body, so manufacturers can produce both 840 mm and 900 mm trapezoidal roofing panels with one investment.

This double layer roof panel machine combines two trapezoidal profiles in one machine: the upper roller set forms 840 mm panels and the lower set forms 900 mm panels, with the material path switched by adjustable feeding guides. Two trapezoidal profiles in one machine let you offer two popular roof profiles without buying two separate lines. The space-saving dual-layer design reduces workshop floor space by 40–60% compared with two single machines. Fast and flexible profile changeover takes only 5–15 minutes, minimizing production downtime between runs. High-precision roll forming is delivered by precision-machined rollers, ensuring accurate panel dimensions, consistent trapezoidal profiles and smooth finished surfaces. The standard configuration — 12 and 14 forming stations, 350H welded frame, 5.5 kW main motor and heavy-duty double-row chain drive — is a production-proven package backed by more than 20 blueprint records.

Suitable for color-coated and galvanized steel coil, the machine is widely used for roofing and wall cladding in workshops, warehouses and prefabricated buildings.
