Products Overview
The Double Layer Roofing Sheet Roll Forming Machine is designed to efficiently produce two different types of roofing sheets in one compact system. This machine allows for the simultaneous production of two distinct profiles, such as corrugated and trapezoidal sheets, or other custom profiles, increasing production flexibility and reducing equipment costs. By combining two forming lines into one, it offers a significant space-saving advantage in factories, while maintaining high production speeds of up to 30-40 meters per minute. With automatic control systems, quick profile adjustments, and high-quality output, this machine is ideal for metal roofing sheet manufacturers looking to optimize production capacity.
Products Description

The Double Layer Roofing Sheet Roll Forming Machine is built to enhance the efficiency and scalability of metal roofing production lines. Its advanced PLC control ensures precise control over material feeding, shaping, and cutting, ensuring high-quality roofing sheets with minimal waste. Whether you're producing large-scale orders or customized designs, this machine supports a wide range of materials, including galvanized steel, PPGI, and aluminum. The ability to switch between two profiles seamlessly provides manufacturers with the flexibility to meet varying market demands, making this system perfect for large-scale projects, such as commercial and industrial building roofs. Additionally, its robust design guarantees long-lasting performance, even under continuous operation, offering reliable performance for years to come.
The design of the shaping unit and the synchronizing rod adjuster is the core to ensuring the efficient and precise operation of the double-layer roof panel forming machine. The shaping unit is manufactured from high-strength materials and undergoes precision machining, enabling stable performance under high-load conditions and ensuring the quality and stability of the panels during production. The synchronizing rod adjuster plays a crucial role by accurately adjusting the gaps between the rollers, thereby achieving precise control over different panel profiles and material thicknesses. Through this adjustment system, the production line can easily adapt to the requirements of panels with varying specifications, while reducing errors caused by improper adjustments during the production process, thereby enhancing both production efficiency and panel precision.


The 17-meter automatic cutting machine is a highly efficient and precise device, specifically designed for the automatic cutting and length-setting of long-sized metal sheets. This equipment achieves fully automated operation through an advanced PLC control system. Operators only need to set the cutting length, and the machine can automatically complete the feeding, positioning, and cutting processes, significantly improving production efficiency. Its precision cutting tools and high-rigidity frame design ensure stability and accuracy during the cutting process, making it particularly suitable for factories engaged in large-scale production. Whether for steel plates, aluminum sheets, or other metal materials, the 17-meter automatic cutting machine delivers high-quality cutting results, meeting industry demands for efficiency and precision.

Column Structure and Bearings
The connection between the frame and the columns adopts a keyway and stepped design, ensuring structural stability and convenient installation.

Chains and Sprockets
The chains and sprockets are made of high-strength materials, ensuring stable and durable transmission system performance, capable of withstanding prolonged high-load operation.

Nuts and Caps
Each station is equipped with a fine-tuning scale nut and a protective cap, allowing operators to make precise adjustments, thereby enhancing the tuning accuracy and stability of the equipment.
sample

Samples serve as a crucial quality control step in our production line. Each sample undergoes rigorous inspection and verification to ensure compliance with design specifications and customer requirements. Through sample production, customers can visually assess the forming effect of the equipment and evaluate the precision and stability of the product. This not only helps enhance customer trust but also provides a reliable foundation for subsequent mass production.
During the sample-making process, we use the same materials and processes as in actual production, ensuring accuracy in material thickness, shape, dimensions, and other aspects. These samples are provided to customers for testing and evaluation, guaranteeing smooth equipment operation and meeting the specific requirements of the project. Through sample confirmation, customers can further adjust production line configurations, optimize workflows, and ensure the quality and performance of the final product.
