Roof Curving Machine

Xinnuo XN-Auto Curve Roof Panel Curving Machine – Precision Bending for Arched Roofing Systems

The XN-Auto Curve Roof Panel Curving Machine by Xinnuo is a compact, efficient, and intelligent piece of equipment specifically designed to produce arched roof panels from pre-formed color steel sheets. Its primary function is to bend straight panels into smooth, accurate curves—perfect for dome roofs, curved awnings, or arched steel structures.

Product Parameters

Smart, Controlled Curving Process

This curving machine operates using three controlled feeding steps to gradually form the arc, avoiding sharp bends or material damage. The system incorporates a stepper motor (4 kW) for precise incremental feeding and a hydraulic motor (3 kW) that powers the curving mechanism. This dual-motor setup ensures smooth motion and highly consistent curving across a wide range of panel lengths.

High-Quality Components for Long-Term Use

The machine’s structure is made of solid steel, and its rollers use 45# high steel with hard chrome plating, providing wear resistance and durability. The shaft diameter of 70 mm ensures strength and rigidity during operation. A Cr12 high steel crimping mould is applied to ensure accurate, burr-free curves on every panel.

Flexible Material Compatibility

The XN-Auto Curving Machine is capable of processing color steel plates with thicknesses between 0.3 mm and 0.8 mm and a maximum panel width of 1250 mm, depending on the input profile. This wide material range allows for curving a variety of roofing panel styles, including trapezoidal and corrugated profiles.

Intelligent Control & Efficient Output

Equipped with a Delta PLC system featuring a touch screen interface and inverter, the machine provides an easy-to-use and highly flexible operation. Users can adjust feeding length, curving depth, and stepping speeds directly from the control box, ensuring quick changeovers and high precision for different project needs.

The typical productivity ranges from 5–10 meters per minute (excluding cutting time), making it suitable for both medium and high-volume roofing production lines.

Compact and Easy to Integrate

With dimensions of 2300 × 1650 × 1600 mm and a weight of about 1.5 tons, this machine is space-saving and easy to position within existing production layouts. The wheel gear drive system, powered by a stepper motor, ensures smooth operation with minimal vibration.

Conclusion

Xinnuo’s Roof Curving Machine is a reliable solution for creating curved roof profiles with high precision and minimal effort. Whether for warehouses, stadiums, or shelters, it empowers builders to add architectural value and functional strength to their metal roof structures. Durable, programmable, and efficient—this machine is a key tool for advanced roofing fabrication.
