Automatic Trapezoidal Roofing Sheet Roll Forming Machine Line

This trapezoidal roll forming machine is designed for high-efficiency production of trapezoidal metal roofing sheets widely used in industrial and commercial buildings. The machine forms metal coils into trapezoidal profiles through precision roll forming stations and cuts them automatically according to preset length.

The production line integrates decoiler, feeding system, roll forming section, hydraulic cutting device, and PLC control system. It ensures stable operation, accurate forming, and continuous production, making it ideal for large-scale manufacturing.

With a robust welded steel structure and advanced hydraulic system, the equipment guarantees long service life, reliable performance, and consistent product quality.

Production Process

The production starts with loading the metal coil onto the decoiler. The sheet is fed into the roll forming section, where it is gradually shaped into a trapezoidal profile by multiple rollers. After forming, the hydraulic cutting system cuts the sheet to the desired length, and the finished panels are automatically discharged.

Application

The trapezoidal roofing sheets produced by this machine are widely used in industrial plants, warehouses, agricultural buildings, and prefabricated steel structures. These panels offer high strength, durability, and excellent resistance to harsh weather conditions.
