Main Features
Precision trapezoidal forming: The forming rollers gradually shape the metal sheet, helping maintain accurate rib geometry and a smooth finished surface.
Automatic PLC operation: The touch-screen control system allows operators to set sheet length, production quantity and cutting data conveniently.
Hydraulic cut-to-length system: The profile-matched cutting die produces clean sheet ends and consistent finished panel lengths.
Strong machine structure: The welded steel base and reinforced frame improve stability during continuous production.
Custom profile solution: Roller tooling and cutting dies can be manufactured according to customer's local roof panel profile standard.
Flexible line configuration: Decoiler, feeding guide, punching unit, film covering device, stacker and output table can be selected according to automation needs.
Working Process
The standard working process is: metal coil loading → decoiling → sheet guiding → continuous roll forming → encoder length measuring → hydraulic cutting → finished trapezoidal roof panel output. For higher automation, the line can be equipped with hydraulic decoiler, leveling device, punching unit, protective film device and automatic stacker.
Finished Panel Applications
The trapezoidal roofing sheets produced by this machine are suitable for industrial plants, logistics warehouses, steel structure buildings, commercial workshops, farm buildings, garages, temporary buildings, prefabricated houses and exterior wall cladding. The trapezoidal profile provides practical strength, fast installation, good drainage performance and a modern metal building appearance.
Production Benefits
