Corrugated Sheet Roll-Forming Line — A professional manufacturer offering comprehensive solutions covering the entire spectrum of roofing and flooring applications, with one-stop delivery from steel coil to finished product.
I.Series Overview
The Corrugated Sheet Roll Forming Line is a complete cold-roll forming production system designed for manufacturing various metal corrugated sheets, roofing panels, and floor decking used in construction. Metal corrugated sheets are created by processing metal materials through cold-roll forming or press forming to produce a surface featuring a regular, repeating corrugated rib structure. Utilizing a continuous cold-roll forming process, this equipment series integrates the entire workflow—uncoiling, guided feeding, roll forming, cut-to-length shearing, and discharge—into a single pass, directly producing finished corrugated sheets.
Cold-roll forming is a high-speed, continuous manufacturing process that shapes metal coils or strips into profiles—such as corrugated sheets, trapezoidal sheets, glazed-style tiles, and floor decking—by progressively bending the material transversely through a series of forming rollers. Compared to traditional stamping or bending methods, cold-roll forming offers significant advantages, including high material utilization, superior forming precision, high production efficiency, and lower costs.
In 2025, global revenue from metal corrugated sheets stood at approximately RMB 75.19 billion; this figure is projected to reach nearly RMB 106.61 billion by 2032, representing a compound annual growth rate (CAGR) of 5.1%. Metal roofing machines are specialized equipment used to process and install metal roofing panels; they are widely employed in roofing construction for industrial plants, commercial buildings, and large-scale public facilities.
This equipment series covers four major product categories for roofing and flooring applications: corrugated roofing sheets, T-profile roofing sheets, glazed-style roofing tiles (3D roofing panels), and floor decking. It is compatible with a wide range of materials—including color-coated steel, galvanized steel, Al-Zn coated steel, stainless steel, and aluminum-magnesium-manganese alloys—and handles material thicknesses ranging from 0.3 mm to 1.5 mm. The equipment features fully automatic PLC control and a touchscreen HMI, ensuring a continuous, automated workflow from uncoiling to the discharge of finished products.
