Hebei Xinnuo Roll Forming Machinery Co., Ltd. (XINNUO) has built cold roll forming equipment since 1995 in Botou, Hebei, China. From a factory area of nearly 100,000 m² with 11 large workshops and more than 50 sets of high-precision CNC machine tools, we supply roof panel machines, purlin lines and sandwich panel production lines to customers worldwide. This 840+840 double layer metal roof panel roll forming machine is built as a stainless steel line for producers who need two roof sheet profiles from one compact machine.

Two independent forming systems are stacked in one frame, so the upper and lower layers run two different roof sheet patterns without a second machine. Each layer keeps its own roller set for repeatable profile quality. Both layers are built to the 840 mm working width, and changing production from one layer to the other takes only minutes. The compact machine structure saves 40–60% workshop space against two single machines, which matters when floor area is limited.
Hardened, chrome-plated rollers run stainless steel, color-coated and galvanized coils with stable profile accuracy and a long service life. A fully automatic PLC control system with touch screen sets sheet length, production quantity and forming speed, and the hydraulic cutting unit delivers a clean cutting edge without sheet deformation. Adjustable forming speed matches different capacity requirements, and one or two operators can run the whole line from coil feeding to panel stacking.

This double layer metal roof panel roll forming machine makes 840 mm trapezoidal roof and wall cladding panels for workshops, warehouses and prefabricated buildings, including stainless steel roofing projects. For other configurations, browse our Double Layer Roll Forming Machine category; if a single trapezoidal profile is enough, see the Trapezoidal Sheet Roll Forming Machine collection. Layer count, profile drawing and voltage are customizable, with one-stop service from selection and design to installation and after-sales support.
