Double Layer Roof Panel Forming Machine | 840+900 Trapezoidal Roof Panel Line

Hebei Xinnuo Roll Forming Machinery Co., Ltd. (XINNUO), formerly Botou Huayu Roll Forming Machinery Factory, was founded in 1995 in Botou, Hebei — China's cold roll forming equipment industrial base. A national high-tech enterprise, XINNUO runs two production bases of over 100,000 m² with ISO9001 and CE certifications, exporting to more than 140 countries and regions. The 840+900 double layer roof panel forming machine is one of our most popular two-in-one systems: two complete forming lines are stacked in one frame to make both 840 mm and 900 mm roofing panels with a single machine.

Instead of buying two separate machines, fabricators run one double layer roof panel forming machine and switch the material path between the upper 840 mm and lower 900 mm roller sets when production changes. Each profile has its own independent forming system, letting operators change over in about 5–15 minutes with minimal downtime. The double-layer design combines two production lines into one compact system, saving 40–60% floor space and equipment investment.

Precision-machined, chrome-plated rollers ensure accurate dimensions, consistent profiles and smooth finished sheets. Continuous roll forming supports stable high-speed production of 8–15 m/min to raise output, while the PLC control system sets sheet length, production quantity and forming speed with ease. Hydraulic shearing cuts each sheet to the programmed length automatically, and one or two workers can run the line from coil feeding to panel stacking.

Working with 0.3–1.2 mm color-coated or galvanized coil, it makes trapezoidal roofing and wall panels for workshops, warehouses, steel structure plants and prefabricated buildings. For other profile combinations, browse our Double Layer Roll Forming Machine category; if one trapezoidal profile is enough, see the Trapezoidal Sheet Roll Forming Machine collection. Thickness, profile depth, cutting length and voltage are all customizable, with one-stop service from selection and drawing design to installation, commissioning and lifetime technical support.
