Double Layer Roll Forming Machine – Versatile Roofing Sheet Production

In today’s competitive roofing market, efficiency, flexibility, and space-saving solutions are more important than ever. That’s where the double layer roll forming machine comes into play. Designed for manufacturers who require multiple roofing profiles without investing in two separate lines, this machine by ZTRFM  delivers dual functionality in one compact system — saving time, space, and cost.

Double Layer Roll Forming Machine

Whether you’re producing corrugated panels, R-panels, or other custom profiles, this equipment is engineered to meet your production needs with precision and reliability.

What is a Double Layer Roll Forming Machine?

A double layer roll forming machine is a type of cold roll forming equipment that can produce two different types of metal roofing sheets using a shared base frame. Operators can switch between two profiles — such as a corrugated sheet and an AG panel — by simply adjusting the control settings, without needing to change tooling manually.

This dual-purpose solution is ideal for businesses that serve diverse customer demands but want to keep their workshop footprint compact.

Key Benefits of Double Layer Roll Forming Machine

✅ Two Profiles, One Machine

The ZTRFM model is equipped with two sets of rollers and cutters — each tailored to a specific profile. This allows seamless switching between profiles like the PBR (R panel) and corrugated roofing sheets, reducing downtime and increasing output.

✅ Fast, Consistent Production

With a production speed of up to 30 meters per minute, this machine meets high-volume manufacturing needs without compromising on quality. A Delta PLC control system ensures cutting accuracy within ±2mm, essential for projects requiring consistent sizing.

✅ Rugged Construction

The entire frame is built on 350H beam steel, while the rollers are made of D2 hardened steel and finished with hard chrome plating. The 75mm diameter shafts are treated for strength and durability, ensuring long-term stability under continuous operation.
