The double-layer roll forming machine, often referred to as a double-deck roll forming machine, is an innovative solution designed to maximize efficiency in constrained workshop spaces. This advanced equipment enables the simultaneous production of two distinct profiles, making it a highly cost-effective choice for manufacturing. Widely adopted across industrial facilities and steel structure applications, this machine has gained popularity in markets spanning the United States, Canada, India, Russia, Australia, Asia, Europe, the Middle East, and beyond. Supplied by leading Chinese roofing sheet machine manufacturer Sequoia King Roll Forming, the double-layer roll forming machine showcases strong global demand and promising market potential.
Advantages Over Standard Machines
Compared to standard roll forming machines, the double-deck model offers significant advantages. Equipped with two layers of forming rollers, it effortlessly produces a variety of metal roofing sheets and wall panels. Its adjustable palletizing system accommodates the height differences between the two layers, ensuring seamless operation. This versatile machine can craft diverse products, such as corrugated steel sheets, wall panels, roof panels, or deck panels, all tailored to specific requirements. By consolidating production into a single unit, it saves valuable workspace and boosts operational efficiency.
The double-layer roll forming machine features two guiding tables, a robust roll forming system, and a precision cutting-to-length mechanism, enabling high-speed production of dual-layer roofing sheets. Key highlights of this equipment include:
- Effortless Profile Switching: Transition between two profiles quickly and easily via an intuitive PLC interface, eliminating the need for manual roller adjustments.
- Space and Cost Efficiency: Its compact design reduces footprint and operational costs for manufacturers.
- High-Speed Performance: Optional production speeds of 20, 30, 40, 50, or 60 meters per minute, paired with a non-stop flying cut and fully automated stacking system, allow for exceptional output, reaching up to 60 m/min.
This cutting-edge machine combines versatility, speed, and efficiency, making it an indispensable asset for modern manufacturing facilities aiming to optimize production while minimizing space and costs.
