Automatic Trapezoidal Roofing Sheet Roll Forming Machine

This trapezoidal roll forming machine is specially designed for producing trapezoidal metal roofing sheets widely used in industrial buildings and steel structure construction. The machine processes metal coils into precise trapezoidal profiles through multiple forming stations and cuts them automatically to preset lengths.

The production line integrates decoiler, feeding system, roll forming section, hydraulic cutting system, and PLC control system. It ensures stable operation, accurate forming, and high efficiency production. The added safety guard design enhances operator safety during production.

With a heavy-duty welded steel frame and high-quality components, this machine delivers long service life, consistent performance, and reliable output quality.

Production Process

The process begins with loading the metal coil onto the decoiler. The sheet is fed into the roll forming system, where it passes through multiple rollers to gradually form the trapezoidal profile. After forming, the hydraulic cutting system cuts the sheet to the required length, and the finished panels are automatically discharged.

Application

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