5.1 Product Overview
The double layer roof panel roll forming machine is an upgraded multi-functional cold forming equipment specially designed for diversified metal roofing production needs. Unlike traditional single-layer forming machines, this two layer roof sheet machine adopts dual-layer integrated structure, which can process two different specifications of color steel roof panels, or match roof and wall panel production in one equipment.
This automatic double layer roofing forming line is compatible with PPGI, PPGL and galvanized steel coils with thickness from 0.3mm to 0.8mm. It realizes automatic feeding, leveling, roll forming, hydraulic fixed-length cutting and finished product output. With one machine for dual purposes, it effectively reduces equipment investment and workshop occupation, becoming the most cost-effective metal roofing processing equipment for small and medium processing enterprises.
