Trapezoidal Panel Arch Curving Machine with 120° Max Bending Capability
These introductions refer only to the production line and configuration shown in the main image. Each machine is custom-built. Metalign welcomes your inquiry and provides the right production line—forming metal into profiles aligned to your needs.
1. Production Line Overview
- This arching line is designed for roofing contractors and steel structure manufacturers seeking efficient, low-investment solutions for curving trapezoidal roof panels on-site.
2. Profile Overiew
- This line curves trapezoidal metal roofing sheets made from 0.3–1mm galvanized or prepainted steel, with 1000mm coverage width. The curved panels suit modular construction and reduce roof joints, improving waterproofing and structural aesthetics.
3. Flow Chart and Production Process
- Manual Feeding → Powered Roller Drive → Hydraulic Arching & Curving
- The operator manually feeds preformed panels into the drive rollers. Driven rollers advance the sheet into the hydraulic arching system, which bends the panel to the desired radius, with a maximum arc angle of 120°. Simple, efficient, and ideal for field use.
