Working Process

The production line starts with a decoiler feeding metal coils into the roll forming section. The sheet passes through multiple forming stations where it is gradually shaped into a trapezoidal profile. After forming, the hydraulic cutting system cuts the sheet to preset lengths, and the finished panels are discharged automatically.

Application

The trapezoidal metal sheets produced by this machine are widely used in roofing and wall systems for factories, warehouses, hangars, agricultural buildings, and prefabricated steel structures. The panels provide excellent structural strength, weather resistance, and long-term durability.
