Product description
CU Solar Mounting Channel Roll Forming Machine
The CU Solar Mounting Channel Roll Forming Machine 2.5MM – 25 m/min by LOTOS Forming is a high precision and efficient production solution designed specifically for manufacturing C and U solar mounting channels used in photovoltaic support systems. This machine is engineered to deliver stable performance, accurate forming, and consistent quality for medium to high volume solar structure production.
The roll forming line is capable of processing steel thicknesses from 1.0 mm to 2.5 mm and supports a wide range of materials, including S235–S550, galvanized steel, cold rolled steel, and Zn-Al-Mg coated steel, ensuring excellent strength and corrosion resistance for outdoor solar installations. With a maximum line speed of 25 meters per minute, the machine achieves an optimal balance between productivity and forming accuracy.
Equipped with a robust roll forming structure and precision-machined rollers, the machine ensures excellent profile straightness, dimensional consistency, and smooth surface finish. The production line can be integrated with servo feeding, punching systems, and servo tracking flying cut-off, enabling accurate hole positioning and precise length control to meet strict solar project requirements.
The machine features a PLC controlled automation system with touch screen HMI, allowing operators to easily monitor production parameters, adjust profile sizes, and switch between different channel specifications efficiently. Its modular design allows customization according to customer drawings, hole patterns, and stacking requirements.
