Customizable Heavy-Duty C8 C21 Double Layer Trapezoidal Roll Forming Machine
The C8 / C21 double layer trapezoidal roll forming machine is a user-friendly, highly efficient system designed to produce two distinct trapezoidal roofing profiles (C8 and C21) on a single compact machine. By integrating two forming layers into one unit, this equipment helps customers save factory space, lower investment costs, and improve production flexibility, making it ideal for both small workshops and on-site construction operations.
Featuring a strong welded frame and high-precision forming rollers, the machine ensures smooth, stable operation and accurate profile shaping at consistent production speeds. Its simple, easy-to-use switching system allows operators to quickly switch between C8 and C21 profiles with minimal training, eliminating the need for complex adjustments and reducing downtime between production runs.
This production line supports a variety of common metal materials, including galvanized steel, color-coated steel, and cold-rolled steel, with customizable sheet thickness and width to meet specific project needs. Whether for standard roofing projects or custom design requirements, the machine can be easily adjusted to produce the exact panels needed for any construction job.
Controlled by an advanced PLC system with a clear touch screen interface, the machine enables fully automated one-button operation, automatic length and quantity setting, and precise cutting process control. This intelligent automation simplifies operation, reduces manual labor, and ensures consistent, high-quality output, making it easy for operators to manage production efficiently and effectively.
