1. Production Line Overview
This ridge cap roll forming line is designed for small to mid-sized
roofing manufacturers focusing on galvanized and pre-painted metal
profiles. Its cost-effective setup, safety-oriented profile, and
stable forming process make it ideal for residential and light
steel building markets worldwide.
2. Profile Description
The metal ridge cap is made from galvanized or pre-painted steel
sheets, with thickness between 0.3–0.6mm. The profile features
symmetrical raised peaks and folded edges for water protection and
installer safety. It's mainly used in metal roof systems as a joint
cover at the ridge section.

Process:
Steel coil is manually loaded and guided into the roll forming
unit, where the sheet passes through 17 forming stations to achieve
its final shape with folded edges. After shaping, a hydraulic
cutter ensures precise cutting to length. The formed ridge cap is
then collected on the output table.
