840+900 Double Layer Roll Forming Machine: The Ultimate Solution for Insulated Metal Roofing
In the modern construction industry, the demand for energy-efficient and durable roofing solutions is skyrocketing. The 840+900 Double Layer Roll Forming Machine is specifically engineered to meet this market need. Manufactured at our state-of-the-art facility in Botou City, Hebei Province, this equipment is a versatile powerhouse capable of producing both standard trapezoidal steel sheets and specialized rubber-plastic cotton insulated boards.
Unmatched Versatility and Cost-Efficiency
The 840+900 model is a "two-in-one" solution that maximizes factory floor space and minimizes equipment investment. With a simple switch operation, this machine can produce 840-type trapezoidal roof sheets (ideal for industrial) or 900-type wall panels. More importantly, it is specially reinforced to handle rubber-plastic cotton boards, making it an essential asset for manufacturers focusing on insulated and soundproof building materials.

Heavy-Duty Manufacturing Standards
We understand that international clients require machinery that can withstand continuous, heavy-duty operation. Our 840+900 machine features a robust 300mm H-beam welded frame and high-strength Φ70mm shafts made from 45# tempered steel. The forming rollers are precision-machined and treated with hard chrome plating, ensuring a smooth surface finish on the rubber-plastic boards and significantly extending the service life of the molds. The hydraulic shearing system utilizes Cr12Mov steel blades for clean, burr-free cuts.
Optimized for Global Export and Operation
We recognize that overseas clients often face varying power standards and require user-friendly interfaces. Therefore, our machines are built with export-ready configurations, including customizable voltage options and intuitive PLC touch screen controls. This makes operation straightforward, minimizing the learning curve for local workers and ensuring high precision in every sheet produced.
