This trapezoidal roll forming machine is a professional production line designed for manufacturing trapezoidal metal roofing sheets used in industrial buildings and steel structure construction. The equipment integrates decoiling, roll forming, hydraulic cutting, and finished sheet output to achieve continuous and efficient production.
The machine is built with a strong welded steel structure and high‑precision forming rollers to ensure stable operation and consistent sheet quality. With PLC automatic control and touch screen interface, operators can easily set parameters such as sheet length, quantity, and production speed.
The produced trapezoidal metal panels are widely used for roofing systems, wall cladding, and industrial construction projects because of their high strength, durability, and corrosion resistance.

The production process begins with loading a metal coil onto the decoiler. The sheet is then fed through multiple roll forming stations where it is gradually shaped into the trapezoidal profile. After forming, the hydraulic cutting device cuts the sheet to the preset length, and the finished roofing panels are automatically discharged.
The trapezoidal roofing sheets produced by this machine are widely used in roof and wall systems for factories, warehouses, hangars, agricultural buildings, and prefabricated steel structures. The finished panels provide excellent load‑bearing strength, long service life, and strong resistance to weather conditions.
