Fully Automatic C Purlin Roll Forming & Punching Production Line for Solar PV Mounting Structures
The C50–160 PV Mounting Roll Forming Solution is a fully automatic production line designed for manufacturing C-shaped cold-formed steel profiles used in photovoltaic mounting structures.
The complete line integrates coil loading, hydraulic decoiling, leveling, strip cutting and butt welding, loop storage, multi-position punching, automatic profile changeover, roll forming, servo tracking hydraulic cutting, intelligent unloading, automatic stacking, conveying and strapping.
The system is controlled by PLC with a touchscreen HMI, allowing operators to monitor production status, set profile length and control the automatic production process from one integrated system.
Designed for C-shaped profiles with a bottom width of 50–160 mm, web height of 30–70 mm and lip width of 10–30 mm.
Suitable for 1.5–3.0 mm strip thickness and steel materials including S350G–S550GD zinc-aluminum-magnesium materials and Q355B–Q550B cold/hot rolled steel.
Servo-driven automatic changeover uses linear guides and ball screws to quickly adjust forming dimensions and reduce changeover time.
The eight-position punching system supports programmable punching operations with adjustable tooling positions and servo feeding.
Servo tracking hydraulic cutting supports continuously adjustable cutting lengths from 1 to 12 meters with a specified cutting accuracy of ±1 mm.
Finished C profiles can be automatically unloaded, aligned, stacked, conveyed and prepared for PET strapping.

The coil storage table can hold up to three steel coils. The loading car is motor-driven, hydraulically lifted and designed for coils up to 5 tons.
Hydraulic expansion is used for automatic coil loading and feeding. The decoiler supports steel coils up to 2000 mm outer diameter and 400 mm width, with pneumatic pressure arm and pneumatic disc brake.
The leveling unit adopts a five-roller configuration with two upper rollers and three lower rollers. The leveling rollers use bearing steel and are designed for stable strip feeding.
The system cuts defective strip ends and prepares the material for butt welding. It supports strip widths up to 400 mm and material thicknesses of 1.5–3.0 mm.
The spiral loop stores approximately 500–800 m of strip material, helping maintain continuous feeding during coil replacement and welding operations.
The multi-position punching system uses servo feeding and hydraulically driven punching stations. Tooling positions can be adjusted along linear guides, while automatic centering guides help maintain punching accuracy.
The forming machine uses 15 forming stations and a 55 kW variable-frequency motor. The roll forming speed is 25–35 m/min. Cr12MoV heat-treated rollers and gearbox transmission are used for the forming section.
The servo tracking cutting system supports continuous length adjustment from 1 to 12 meters. The specified cutting accuracy is ±1 mm.
Finished C profiles are automatically conveyed, aligned, flipped and stacked. The stacking system uses servo-driven movement and adjustable electromagnetic gripping positions.
The automatic packing section uses PET strapping for bundled C-shaped profiles. The system is integrated with the conveying and stacking process for streamlined finished-product handling.
The forming machine is equipped with an automatic quick-change system. The changeover mechanism is driven by a servo motor, linear guide and ball screw, allowing forming dimensions to be adjusted efficiently.
According to the technical specification, one roller set can cover C50–C130 profiles, helping reduce forming tooling requirements and changeover time for multiple profile sizes.
The eight-position punching section is designed for programmable punching operations before the forming process. It combines servo feeding, hydraulic punching stations, adjustable tooling frames and automatic centering guides.
The complete production line adopts PLC control with a 10-inch LCD touchscreen HMI. Operators can set production parameters, monitor machine status and receive fault indications through the interface.
Automatic sequential operation of the complete production line.
Production parameters, product length and machine status can be monitored through the touchscreen interface.
Manual operation is available for individual machine maintenance, while automatic mode controls the complete line.
The line is equipped with a Siemens industrial Ethernet switch for data acquisition and communication.
The automatic stacking system receives C-shaped profiles from the powered roller conveyor and performs pushing, alignment, flipping and stacking operations.
Electromagnetic grippers can be adjusted according to the profile length. Servo-driven movement provides controlled positioning during stacking.
The stacking system supports profile lengths of approximately 2.5–12 m, with a specified stacking package size of 600 × 600 mm.
The C-shaped profiles produced by this line are designed for photovoltaic mounting structure applications and related cold-formed steel applications.
The wide profile range, programmable punching system and automatic changeover configuration make the line suitable for manufacturers requiring multiple C-profile specifications.
Multiple production processes are integrated into one continuous automated line.
Supports C-profile sizes within the specified C50–C160 range.
Automatic unloading, stacking, conveying and PET strapping reduce manual handling requirements.
PLC, touchscreen HMI and industrial communication support centralized production control and monitoring.
