Double Layer Roof Sheet Roll Forming Machine
Double Layer Roof Sheet Roll Forming Machine is designed to produce roofing sheets with two different dimension sizes.
View DetailsTechnical overview
How a roof panel roll forming line is built
The profile decides the machine. Panel width, rib height, rib pitch and the number of ribs per sheet set the coil width, the roll tooling and the shaft spacing long before the frame is drawn.
A single layer line runs one profile at 0–15 m/min. A double layer line stacks two forming trains on one base frame, so the same coil feeds either a corrugated or a trapezoidal panel and a switching device selects the active pass. For exporters selling panels into several markets, the double layer layout removes the cost of a second decoiler, a second control cabinet and the extra floor space they need.
Thin gauges are cut with a post-cut hydraulic flying shear, which keeps the trailing edge free of stop-start marks. Where the profile carries stiffening ribs or a strengthened web, an embossing station sits before the final forming passes. Roof lines are usually bought together with a purlin line for the same steel building package, and the two can share one decoiler and coil car — see building and construction applications or send the profile drawing to our engineering team.

FAQ
Roof Panel Roll Forming Machine — questions buyers ask
Answers come from real quotation discussions. If your question is not here, ask it directly and an engineer will answer.
What is the difference between a single layer and a double layer roof panel line?
A single layer line forms one profile. A double layer line carries two independent forming trains on one base frame and switches between them at the entry, so corrugated and trapezoidal panels come off one decoiler, one hydraulic station and one control cabinet. The double layer build costs more up front but replaces two separate lines and the operators they need.
Which coil widths can the line run?
Standard builds are set for 1000, 1200 or 1250 mm coil. The decoiler mandrel is sized at order and cannot be extended later, so confirm the coil width you will buy before the line is released to production.
How long does installation take on site?
A single layer line is installed and commissioned in 7–10 days with one technician. Double layer lines take 12–18 days. Foundation drawings, wiring diagrams and a commissioning checklist are issued with the shipment so the base can be poured while the machine is in transit.
Can the same line run prepainted and galvanized coil?
Yes. Rollers are chrome plated and the forming passes are set up for prepainted material, so galvanized or galvalume coil runs on the same tooling. Switching between them is a matter of resetting roll gaps, not changing rolls.
