Product Overview
The C8/C21 double layer trapezoidal roll forming machine is a precision-engineered solution designed to manufacture two different trapezoidal roofing profiles (C8 and C21) on a single integrated system. By combining two forming layers into one robust structure, this equipment optimizes production efficiency, reduces capital expenditure, and enhances operational flexibility, making it a top choice for high-volume roofing sheet manufacturers.
Built with a rigid, reinforced welded frame and precision-machined forming rollers, the machine guarantees exceptional stability and dimensional accuracy for every C8 and C21 panel produced, even under continuous, high-load operation. Its efficient switching mechanism enables quick profile changes, allowing manufacturers to meet the needs of projects requiring multiple roofing sheet types without downtime or complex reconfiguration.
The production line is compatible with various metal materials, such as galvanized steel, color-coated steel, and cold-rolled steel, with customizable thickness and sheet width to align with unique project requirements. This material versatility ensures the machine can adapt to a wide range of construction applications, from small-scale residential builds to large-scale commercial and industrial roofing projects.
Powered by a state-of-the-art PLC control system with a responsive touch screen interface, the machine offers fully automated operation, including one-button start, automatic length and quantity programming, and precise cutting control. This smart system enhances production consistency, reduces human error, and maximizes material utilization, helping businesses deliver high-quality roofing panels on time and within budget.
Frequently Asked Questions
How many people are required to operate the machine?
It requires just one operator plus one person to handle the output; for highly automated models, a single person is sufficient.
How long is the warranty period?
The entire machine comes with a 12-month warranty, excluding wear parts.
What service can you provide before order?
We provide full pre-sales service, including answers to all your questions about our machines, such as technical parameters, price, payment terms, etc. If you would like to visit our factory and inspect the machines, we can send you an invitation letter and offer you our warmest welcome.
Can it be integrated into a complete color steel production line?
Yes, it can—forming a fully automated line covering uncoiling, leveling, roll forming, shearing, and stacking.
How should the machine be stored when not in use for an extended period?
Disconnect the power, clean the machine, apply anti-rust oil, cover it with a dust cover, and store it in a dry environment.
