Hydraulic arch camber curving equipment for forming smooth and accurate curves on pre-formed metal roofing sheets.
The Metal TR4 Roofing Sheet Crimping Machine is a hydraulic arch curving machine designed for forming small and fine curves on pre-formed metal roofing panels.
The hydraulic curving process creates a smooth and controlled camber on the roofing sheet, making it suitable for curved and arch-style roof structures.
Curved roofing panels can help reduce the requirement for roof purlins and steel components in suitable applications, providing a practical and economical solution for certain architectural roofing projects.
The finished curved roof can also provide a strong, durable and visually attractive appearance, making it suitable for modern industrial and commercial buildings.

Hydraulic forming provides controlled pressure for smooth and consistent arch curving of metal roofing sheets.
Designed for producing small and fine curves on designated pre-formed roofing panels.
The machine adopts a full automatic portable PLC control system for convenient operation.
The main frame is constructed from H400 welded steel for stable and durable operation.
