Our double layer roof panel forming machine is a practical and cost-effective dual-purpose roll forming equipment specially designed for metal roofing factories, steel structure contractors and building material suppliers. This single machine can produce two different profiles on one production line, including corrugated roof sheets, trapezoidal roof panels, wall cladding panels and other popular metal sheets. As a professional foreign trade export manufacturer, we supply heavy-duty, low-noise, high-output double layer roof machines with strict quality inspection and full set of export services. It is the best-selling roll forming equipment for small and medium factories all over the world.

Many overseas buyers want to expand their roofing sheet production business, but face limited workshop area and tight investment budget. Buying two separate roll forming machines costs more money, occupies more space and requires more workers to operate. Our double deck roof panel forming line perfectly solves these problems. It adopts upper and lower two-layer roller arrangement, one set of uncoiler, one control cabinet and one cutting system to realize two kinds of metal panel production. The machine runs smoothly 24 hours a day, easy to operate, low failure rate, greatly improving production flexibility and market competitiveness.

Main Profiles Our Double Layer Roof Machine Can Produce

We can customize the upper and lower layer profiles according to local popular building styles and customer market demands:

Trapezoidal roof panel: 840, 900, 1000, 1050 standard trapezoidal sheets for warehouse, factory, workshop, steel structure building roofing

Corrugated roof sheet: classic wave profile, waterproof, wind resistant, widely used in rural houses, temporary buildings, simple shelters

Wall cladding panel: exterior wall decorative metal panel, heat insulation matching profile for building outer wall enclosure system

Custom local special profiles: according to customer’s drawing or sample, adjust roller design to match local popular roof sizes in different countries

Why Global Buyers Prefer Our Double Layer Roof Panel Machine

One Machine Two Functions, Save Investment & Workshop Space

No need to purchase two independent roll formers. One double layer machine can produce two kinds of roof and wall panels. It saves at least 40% equipment cost, reduces workshop occupation area by half, and only needs one operator to manage the whole line. Ideal choice for new startups, small factories, local building material distributors and construction engineering companies.

Heavy Welded Steel Frame, Stable Running Without Vibration

The main frame adopts thick large H-beam and integral steel plate welding structure, with stress relief treatment to ensure long-term running stability. The whole machine will not shake or deform during high-speed continuous production. All forming rollers are made of high-quality 45# steel or alloy steel, hard chrome plated surface, anti-rust, anti-wear, long service life. The finished roof panel surface is smooth, no scratches, no burrs, beautiful and neat.

PLC Full Automatic Control, Simple Operation for All Workers

Equipped with international standard PLC controller and multi-language touch screen (English, Spanish, Arabic, Russian etc.). Workers only need to set length and quantity on the screen, then the machine automatically completes feeding, leveling, roll forming, counting and hydraulic cutting. The system can store multiple production formulas, one-key switch between upper layer and lower layer production. Even inexperienced workers can operate skillfully in a short time.

High Forming Speed & High Precision, Meet Large Orders

Adopt high-speed chain transmission or gearbox synchronous drive system. The production speed can reach 20–35 meters per minute, meeting large batch order delivery requirements. The cutting error is controlled within ±2mm per 10 meters, the sheet flatness is good, no bending deformation, fully meeting local construction standards and project acceptance requirements in various countries.

Wide Raw Material Compatibility & Weather Resistance

The machine can process color steel coil, galvanized steel coil, aluminum zinc coil, aluminum coil and other raw materials, material thickness from 0.3mm to 0.8mm. The produced roof panels have strong wind resistance, waterproof performance and corrosion resistance, suitable for high temperature, rainy, coastal and windy areas all year round.

Low Noise & Low Failure, Easy Daily Maintenance

Optimized silent transmission design, whole machine running noise ≤75dB, meeting environmental protection factory standards. All electrical components are well-known international brands, stable performance and long service life. Wearing parts are standard universal parts, easy to purchase and replace locally overseas, greatly reducing later maintenance cost and downtime loss.
