1. Overview
1.1 Production Line
This roll forming line is designed for producers of conventional metal roof panels and caters to roofing manufacturers across global markets. It delivers a reliable, efficient, and highly adaptable production solution, equipped with hydraulic punching and cutting systems that ensure precise, clean operations. Ideal for medium- to large-scale production, the line enhances product quality while improving workplace safety and operational efficiency. Its flexible design allows manufacturers to adjust settings for different panel profiles, material types, and production speeds, making it a versatile choice for meeting diverse project specifications.
1.2 Profile
The traditional metal roof tile profile is made from galvanized or color-coated steel coils, 0.3 to 0.8mm thick. Its shape mimics classic roof tiles with embossed texture and perforations for drainage. Durable and lightweight, it is ideal for residential and commercial roofing applications requiring aesthetic appeal and weather resistance.
- Material: Galvanized Steel / PPGI / Aluminum
- Thickness: 0.3-0.8mm
- Yield strength: 200 - 350 Mpa
- Tensile stress: 200 -350 Mpa
1.3 Production Process
Flow Chart: Hydraulic Decoiler → Entry Guide → Roll Former → Hydraulic Punch → Hydraulic Cutter → Auto Stacker
Steel coils are decoiled and guided precisely into a chain-driven roll former with safety cover, shaping the metal into traditional roof tile profiles. Hydraulic punching creates drainage and decorative holes, followed by hydraulic cutting to precise lengths, ensuring quality and efficiency.
1.4 Key Focus
- Robust chain-driven roll former with protective chain cover for enhanced safety
- Precise hydraulic punching for functional perforations
- Accurate hydraulic cutting for clean edges
- Efficient 7T decoiler and automated stacking system
- Boosted productivity while maintaining high product quality and operator safety
