Product Overview
The C8 / C21 double layer trapezoidal roll forming machine is a high-efficiency, cost-effective solution designed to produce two distinct trapezoidal roofing profiles (C8 and C21) on a single compact machine. By integrating two forming layers into one structure, this equipment significantly reduces factory space requirements, cuts investment costs, and improves production flexibility, making it an essential asset for mass-production roofing sheet manufacturers.
Built with a heavy-duty welded frame and precision-engineered forming rollers, the machine ensures stable, continuous operation and accurate profile shaping at high production speeds. Its fast-switching system allows for seamless transitions between C8 and C21 profiles, enabling factories to maximize output and meet tight production deadlines for multiple roofing sheet orders.
This versatile production line supports a variety of raw materials, including galvanized steel, color-coated steel, and cold-rolled steel, with customizable sheet thickness and width to match specific project needs. This material flexibility ensures the machine can handle a wide range of construction applications, from small residential builds to large-scale commercial and industrial roofing projects.
Powered by an advanced PLC control system with a user-friendly touch screen interface, the machine enables fully automated one-button operation, automatic length and quantity setting, and precise cutting control. This intelligent automation boosts production efficiency, reduces labor costs, and minimizes material waste, helping businesses achieve higher profitability while maintaining consistent, high-quality roofing panel output.
