Hebei Xinnuo Roll Forming Machinery Co., Ltd. (XINNUO), in Botou, Hebei — the heart of China's cold roll forming industry — has built roll forming and roofing equipment for more than 30 years, with an annual output of over 3,000 sets and exports to more than 140 countries and regions. Our hydraulic roof panel curving machine is a dedicated arch forming unit that curves pre-formed metal roofing panels into smooth, uniform arcs for arched roofs, warehouses, and large-span industrial and agricultural buildings.





The arch radius is adjusted directly on a PLC touch screen, so operators set the required curvature without mechanical recalibration. Both convex and concave arch forming are supported, and every panel keeps the same consistent curvature — exactly what large-span construction projects demand.
Forming follows a gentle step-by-step crimping sequence rather than a sharp single bend. Sheets move through progressive roller stages without wrinkling, cracking or coating peeling, which protects the surface of PPGI, galvanized and galvalume material and keeps the finished arch clean and corrosion-resistant.
A heavy-duty hydraulic power unit delivers stable pressure output with low noise, so the machine runs reliably through long, continuous production shifts with minimum interruption.
The machine accepts a wide range of profiles and materials: trapezoidal sheets, IBR sheets, galvanized steel, color coated steel and aluminum sheets. It pairs naturally with panels produced by our Trapezoidal Sheet Roll Forming Machine and can be configured to the exact profile drawing you supply.
Built on a reinforced heavy-duty welded frame with hard-chrome plated rollers and quenched shafts, the machine resists deformation under heavy load, giving it a long service life and low maintenance cost even in daily high-volume production.
Send us your panel profile drawing and required arch radius — our engineers will confirm the roller configuration, frame grade and voltage for your project. For the matching panel forming lines, browse the Roof Sheet Making Machine category to complete your arched roof production line.
