The 3-Layer Roof Panel Roll Forming Machine is an automated production line designed to manufacture **composite sandwich panels by continuously forming and bonding two outer metal layers (e.g., galvanized steel, aluminum) with an inner insulation core (e.g., polyurethane foam, rock wool, EPS), creating high-strength, thermally efficient roofing panels.
1. Product Features & Advantages
High Strength Metal layers (0.3-1.0mm thick) + core resist wind loads (ideal for typhoon-prone areas).
Thermal/Acoustic Insulation: PU/rock wool cores (thermal conductivity: 0.022-0.045 W/m·K) reduce energy costs.
Lightweight: 80% lighter than concrete roofs, minimizing structural load.
Fast Installation: Prefabricated locking/flanging designs cut installation time by 50%.
2. Applications
Industrial: Warehouses, factories (column-free spans up to 30m).
Commercial: Shopping malls, stadiums, airports.
Cold Storage: Freezer roofs (PU core resists moisture).
Disaster Relief: Rapid construction of temporary housing.
3. Purchasing Guide
(1) Key Parameters
Panel Width: 600-1200mm (effective coverage).
Core Thickness: 30-200mm (impacts insulation).
Line Speed: 5-15 m/min (slower for PU curing).
(2) Brands & Pricing
Premium Import: Italy's FOMI, Korea's SAMICK ($500K-$1M USD, high precision).
Chinese Quality: Shanghai Gangzhijie, Guangdong Jingang ($200K-400K USD, cost-effective).
Budget Option: Used European machines ($100K-200K USD, higher maintenance).
(3) Considerations
Fire Certifications: Match local codes (e.g., Mexico's NOM-127).
After-Sales: Prioritize suppliers offering roller repair and core formula support.
8. Industry Trends
Eco-Materials: Bio-based PU, recycled rock wool cores.
Smart Manufacturing: IoT sensors for real-time density/foam quality monitoring.
Customization: Non-standard profiles (e.g., curved roofs, solar-integrated panels).
