The production process begins with loading metal coils onto the decoiler. The sheet is fed into the roll forming system where it passes through multiple forming stations that gradually shape it into a trapezoidal profile. After forming, the hydraulic cutting system cuts the sheet according to the preset length, and the finished panels are automatically discharged.
The trapezoidal roofing sheets produced by this machine are widely used in roof and wall systems for factories, warehouses, agricultural buildings, logistics centers, and prefabricated steel structures. The finished metal panels offer excellent load‑bearing capacity, durability, and weather resistance.
