I. Equipment Overview

The wall and roof panel roll forming machine is a highly efficient integrated cold-forming equipment designed for building envelope systems. It can simultaneously produce profiled metal panels suitable for both walls and roofs. Using continuous cold roll forming technology, the machine processes metal coils (such as color-coated steel sheets, galvanized steel sheets, aluminum-magnesium-manganese sheets, etc.) in a single pass into building envelope panels with high structural strength, excellent waterproofing performance, and a smooth appearance. It is suitable for various steel structure and prefabricated building projects, including industrial plants, logistics warehouses, stadiums, and commercial complexes.

II. Core Technical Features

Multi-Functional Integrated Design

• Capable of producing wall panels, roof panels, special-shaped panels, and more, serving multiple purposes with one machine.

  
  

• Supports various cross-sectional shapes: corrugated panels, trapezoidal panels, hidden lock-seam panels, standing seam panels, etc.

  
  

• Quick roller change system for switching between different panel types (changeover time ≤ 30 minutes).

  
  

High-Precision Forming System

• Forming rollers are made of Cr12MoV mold steel, heat-treated to a hardness of HRC 58-62, ensuring wear resistance and durability.

  
  

• Servo adjustment of roll gap, pressure, and angle with an accuracy of ±0.1 mm.

  
  

• Progressive multi-pass forming effectively controls material springback and deformation.

  
  

Intelligent Control System

• PLC + industrial touchscreen control, supports recipe storage and one-touch recall.

  
  

• Automatic fixed-length cutting with an accuracy of ±1.0 mm.

  
  

• Integrated online inspection system for real-time monitoring of panel thickness, profile, and surface quality.

  
  

• Optional remote monitoring and production data management system.

  
  

Flexible Production Configuration

• Material thickness range: 0.4-1.2 mm (expandable to 2.0 mm).

  
  

• Material width range: 300-1200 mm (customizable).

  
  

• Optional functional modules: online punching, embossing, film lamination, automatic stacking, etc.

  
  

Dedicated Panel Type Support

• Wall panels: Can produce sandwich panel facings, single panels, decorative panels, etc.

  
  

• Roof panels: Supports 360° lock-seam panels, standing seam panels, flat lock panels, etc.

  
  

• Accessory panels: Can simultaneously produce flashing plates, eave plates, decorative strips, etc.
