Xinnuo Curving Machine – Precision Arch Bending for Metal Roofing Panels

The Xinnuo Curving Machine is a high-performance, fully automatic system designed for curving pre-formed metal roofing sheets into smooth, durable arched profiles. Engineered with precision and durability in mind, this equipment is essential for producing curved roof sections used in warehouses, aircraft hangars, farm shelters, stadiums, and various modern architectural structures.

Product Parameters

Material Compatibility and Customization

The machine is suitable for processing a wide range of materials including GI/GL (galvanized or galvalume steel) and PPGI/PPGL (pre-painted steel). It supports a thickness range of 0.8–1.2 mm and feeding width of 1220 mm, with full customization options for other width and profile shapes as needed. This allows manufacturers to handle diverse roofing styles and project requirements efficiently.

Heavy-Duty Forming Structure

The forming section is built on a 350 H-beam frame with a reinforced steel structure, ensuring long-term stability under high-load operations. The machine includes rollers made from 45# forged steel with a 0.05 mm chromium coating, offering superior hardness and corrosion resistance. The 70 mm solid shaft diameter ensures that the rollers can handle the pressure of consistent high-volume curving without flexing or failure.

Efficient Cutting and Power System

Xinnuo equips this machine with an automatic cutting system using Cr12Mov blades, heat-treated to 58–62°C for precise, wear-resistant cuts. The forming section is powered by a 5.5 kW motor, while the hydraulic unit operates with 4 kW, offering strong and stable performance during bending and cutting phases.

Speed and Control

This curving machine operates at a typical speed of 10–15 meters per minute, depending on tile shape and material thickness. Controlled via a Delta PLC system, users can easily program the production length, batch quantity, and curve depth through a user-friendly touch screen. The system supports multiple languages, including English and Spanish, making it accessible for global clients.

Bonus Equipment & Power Options

Every unit comes with a manual decoiler (3 tons) included for free, and clients can choose to upgrade to a hydraulic decoiler for added convenience. Voltage can also be adjusted upon request to suit local power standards.

Conclusion

Xinnuo’s Curving Machine is a reliable, fully automated solution for forming beautifully arched roofing panels with industrial-grade strength and finish. Built for precision, longevity, and productivity, it's the perfect investment for businesses in steel structure construction or metal roofing fabrication.
