The production process begins with loading the metal coil onto the decoiler. The sheet is then fed into the roll forming system where multiple forming stations gradually shape it into a 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 facilities, storage buildings, and steel structure construction projects. The finished panels offer excellent load‑bearing capacity, long service life, and strong weather resistance.
