840-900 Roof Panel Roll Forming Machine

840-900 Roof Panel Roll Forming Machine

The 840-900 Roof Panel Roll Forming Machine is a high-efficiency cold roll forming machine designed for producing metal roofing and wall panels with 840 mm and 900 mm effective widths. By integrating two forming profiles into one machine, it provides a practical solution for manufacturers that need to produce different panel types while saving factory space, equipment investment, and operating costs.

The machine is widely used for manufacturing roofing panels for industrial workshops, warehouses, commercial buildings, steel structure projects, agricultural buildings, and residential construction.

Efficient 840 and 900 Profile Production

The 840-900 machine is normally configured as a double-layer roll forming machine, with separate forming sections for the two profiles. Operators can select the required production layer according to the panel specification.

The 840 profile is commonly used for metal roofing applications, while the 900 profile can be used for roofing or wall cladding depending on the customer's profile design. The exact effective width, wave height, pitch, and forming configuration can be customized according to technical drawings.

Automatic Roll Forming Process

The complete production line can integrate decoiling, guiding, feeding, roll forming, hydraulic cutting, and finished-panel output. After entering the required panel length and quantity through the control system, the machine can automatically complete the forming and cutting process.

The PLC control system provides automatic length setting, production quantity counting, parameter adjustment, and operational control, making the equipment easy to operate after basic training.

Durable Machine Construction

The machine is built with a heavy-duty welded steel frame to provide stability during continuous operation. Forming rollers are generally manufactured from high-quality 45# steel with precision machining and chrome-plated surfaces, while solid forming shafts provide reliable power transmission and consistent panel forming.

The hydraulic cutting system uses high-strength Cr12 or Cr12MoV cutting blades, providing clean and accurate cutting without significantly damaging the finished panel surface.

Wide Material Compatibility

The 840-900 roll forming machine can process commonly used metal coils such as PPGI, PPGL, GI, and GL steel. Depending on the selected configuration and profile requirements, material thickness is typically around 0.3–0.8 mm.

A standard production speed is approximately 8–15 m/min, while higher-speed configurations can be customized according to the required output and material specifications.

Flexible Configuration for Global Projects

Power supply, roller stations, machine dimensions, feeding width, control components, cutting system, and decoiler configuration can all be customized to meet different production requirements and local electrical standards.

With its combination of two popular profiles, automatic control, stable forming performance, compact structure, and flexible customization, the 840-900 Roof Panel Roll Forming Machine is an ideal choice for metal roofing manufacturers looking to expand product varieties while maintaining efficient production.
