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.

4. Production Process Analysis

5. Key Focus

• Compatible with 0.3–1mm trapezoidal corrugated steel panels
• Produces up to 120° curved panels with consistent accuracy
• Designed for fast deployment in roofing projects
• Horizontal layout for space-saving and operator safety
• Stable speed at 10m/min ensures steady productivity

6. Customization Options

• We offer customizations based on panel profile geometry, desired bending radius, feeding system integration (semi-auto or full-auto), arching roller structure, and compatible roller surface treatment for prepainted materials. Panel width and control precision can also be tailored for specific project demands.
