High-Speed Metal Roof Corrugated Sheets Rolling Forming Machine (45m/min)

The Metal Roof Corrugated Sheets Rolling Forming Machine is a high-performance production line designed for manufacturing lightweight, durable, and precisely formed roofing sheets.
With a speed up to 45 meters per minute, it is ideal for large-scale industrial roofing projects and global construction applications.

Corrugated metal roofing is widely used worldwide because it is easy to install, weather-resistant, lightweight, and strong under load. To meet growing market demand, our engineering team has developed an upgraded automatic corrugated sheet roll-forming solution with servo-cutting and high-speed gearbox transmission.

Machine Highlights

1. Adjustable Feeding Platform
The hand-wheel adjustable feeding table ensures precise coil alignment and protects edges from scratches during high-speed feeding.

2. Separate Rolling Concept
Each forming station independently releases internal stress from the sheet, keeping the final product smooth and uniform.

3. Rigid Structural Frame
The welded H-beam frame undergoes vibration aging treatment and surface planing to guarantee long-term accuracy and stability.

4. Durable Roller System
All rollers are made of GCr15 or 45# steel, polished and chromed, ensuring a mirror-smooth finish and long service life.

Why It Can Handle Thin Sheets (0.18–0.45mm) Smoothly

• The roller shape is smoothly curved instead of triangular, preventing surface deformation.
• We use one-piece forming rollers, which support both thin and large-wave profiles without coil scratching.
• The GCr15 rollers with 0.06mm hard chrome maintain their glossy surface even after years of operation.

As a result, customers can continuously produce lightweight roofing sheets with perfect surface finish and consistent accuracy.
