Our double layer roofing sheet roll forming machine is a professional, heavy-duty cold roll forming unit, specially built for producing two different types of roof and wall panels in one integrated machine. It combines automatic coil feeding, leveling, roll forming, fixed-length cutting and finished product stacking into one seamless workflow, delivering stable, consistent performance for mass production. Widely used in industrial workshops, warehouses, commercial buildings, residential construction and prefabricated housing projects, this machine is a cost-effective solution for global construction and metal processing businesses looking to boost output and cut equipment costs.

主な利点と主な機能

Dual-Layer Integrated Design, Maximize Production Efficiency

This machine features a unique dual-layer forming structure with two independent roller systems built into one solid frame, allowing it to produce two different profiles (trapezoidal sheets, corrugated panels, glazed roof plates and wall cladding) either separately or at the same time. Unlike traditional single-layer machines, it eliminates the need to invest in two separate units, cutting equipment investment by nearly 50% and saving 60% of workshop space. It also supports fast profile switching without manual roller disassembly, greatly shortening production preparation time and doubling overall output for diversified orders.

Heavy-Duty & Stable Structure, Long Service Life

The main frame is made of thickened welded steel plate with overall annealing treatment, ensuring high rigidity, shock resistance and zero deformation even under 24-hour continuous high-load operation. All forming rollers are forged from high-quality 45# carbon steel, processed by precision grinding and hard chrome plating, offering exceptional wear resistance and extending service life by over 3 times. Driven by a high-power motor and precision gearbox, it runs smoothly at a stable speed of 15-30m/min with minimal downtime and low failure rate.

High-Precision Forming, Consistent Product Quality

Equipped with a PLC intelligent control system and touchscreen HMI, this machine enables fully automatic length setting, quantity counting and fixed-length cutting, with product length tolerance controlled within ±0.5mm. The professionally designed and calibrated rollers ensure every finished panel has a smooth surface, uniform thickness, standard profile size and perfect splicing performance, with no burrs, distortion or bending. It supports custom profile design to meet different regional building standards and client-specific requirements.

Wide Material & Application Compatibility

Compatible with most common metal coil materials, including galvanized steel, color-coated steel, aluminum sheet and aluminum-zinc coated steel, with a material thickness range of 0.3mm to 0.8mm, covering mainstream roofing panel specifications worldwide. Operators can switch between the two layers easily via simple touchscreen parameter adjustment, making it highly flexible for small-batch mixed production and large-scale continuous manufacturing.

Fully Automatic & User-Friendly Operation

The entire production line is fully automated, with a simple and intuitive interface that’s easy to learn and operate—no professional technical background is required for basic operation after short training. It comes with fault self-diagnosis, emergency stop and automatic alarm functions for quick troubleshooting, plus automatic uncoiling, hydraulic feeding and finished product stacking systems to realize unmanned production, reducing labor input and labor costs effectively.

Energy-Saving & Low Maintenance Cost

Optimized electrical system design lowers energy consumption compared with traditional dual-machine setups, making it more eco-friendly and cost-efficient to run. Key electrical components adopt international premium brands (Siemens, Schneider) for stable performance. Daily maintenance is simple, only requiring regular lubrication and routine inspection, cutting long-term operation and maintenance costs for enterprises.
