1. Production Line Overview
This roll forming line is designed for manufacturers serving
high-end roofing markets. It delivers precision, efficiency, and
customizable features for concealed-fix metal roof panels, suitable
for contractors, distributors, and panel fabricators.
2. Profile Description
The profile is a concealed-fix standing seam panel made from
galvanized or pre-painted steel, with a typical thickness of
0.4–0.6mm. The shape allows snap-lock interlocking for superior
wind and waterproof performance. It is widely used in high-end
roofing systems across commercial and industrial buildings.
3. Production Process
Flow Chart:
Decoiler → Guiding → Roll Former → Hydraulic Cutter → Out Table
Process:
The steel coil is manually decoiled and guided into the forming
system. The 18-station roll former with chain drive gradually
shapes the standing seam profile with high precision. The hydraulic
cutter ensures clean cuts at designated lengths. This setup
balances affordability, accuracy, and ease of operation for roofing
panel production.
