This trapezoidal roll forming machine is designed for high‑efficiency production of trapezoidal metal roofing sheets widely used in steel structure buildings. The equipment forms metal coils into trapezoidal panels through multiple precision roll forming stations and cuts them to preset lengths automatically.
The machine adopts advanced PLC control with a touch screen interface, allowing operators to easily set production parameters such as length, quantity, and speed. Its heavy‑duty welded frame and precision rollers ensure long‑term stability and consistent panel quality.
This roll forming production line integrates decoiling, sheet feeding, roll forming, hydraulic cutting, and finished sheet output into a fully automatic process. It greatly improves production efficiency while maintaining excellent forming accuracy.

The production line begins with coil loading on the decoiler. The metal sheet is then guided through the roll forming stations where it gradually takes the trapezoidal shape. After forming, the hydraulic cutting system cuts the sheet to the required length, and the finished panels are automatically discharged onto the output table.
The trapezoidal roofing sheets produced by this machine are widely used for roof and wall systems in factories, warehouses, agricultural buildings, storage facilities, and prefabricated steel structures. These panels provide strong structural performance, long service life, and excellent weather resistance.
