The C8/C21 double layer trapezoidal roll forming machine is a specialized, highly efficient equipment designed for mass production of two distinct trapezoidal roofing profiles: C8 and C21. By integrating two separate forming layers into a single compact machine frame, this innovative system eliminates the need for multiple pieces of equipment, helping customers save valuable factory floor space, minimize upfront investment costs, and improve overall production flexibility.
Built with industrial-grade strength, the machine features a robust, high-rigidity welded frame that guarantees exceptional structural stability during continuous high-speed operation. Equipped with precisely processed high-precision forming rollers, it ensures consistent dimensional accuracy and smooth surface finish for C8 and C21 roofing panels. The user-friendly switching system enables quick, seamless transitions between producing C8 and C21 profiles.
This versatile production line is compatible with various raw materials including galvanized steel, color-coated steel, and cold-rolled steel. The thickness and width of processed sheets can be fully customized to match specific design requirements, providing maximum flexibility for both large-scale commercial projects and residential constructions.
Powered by an advanced PLC control system with a user-friendly touch screen interface, the machine supports one-button operation for enhanced convenience. It enables automatic setting of production length and quantity, ensuring precise cutting control to minimize material waste while improving production efficiency and reducing manual errors.
