Component Specifications

Definition
Outer metal facing is a critical component of insulated wall panel systems, serving as the primary external surface that protects insulation cores from environmental elements. It functions as a weather barrier, structural element, and architectural finish, typically manufactured from coated steel or aluminum sheets formed into profiles that interlock with adjacent panels. This component must withstand wind loads, thermal expansion, UV exposure, and corrosion while maintaining dimensional stability and appearance over decades of service life.
Working Principle
The outer metal facing operates on principles of structural cladding and environmental protection. It transfers wind and impact loads to the panel's structural framework through mechanical fastening or adhesive bonding, while its coated surface reflects solar radiation, sheds water, and resists chemical degradation. The interlocking seam design allows for thermal movement without compromising weather-tightness, and the metal's conductivity helps dissipate static charges and heat.
Materials
Galvanized steel (G90 coating, 0.4-1.2mm thickness) with PVDF or polyester coatings (25-30μm), or aluminum alloy (3003/3004 series, 0.5-1.5mm thickness) with fluoropolymer coatings. Substrates typically have yield strengths of 240-550 MPa.
Technical Parameters
  • Width 600-1200mm
  • Thickness 0.4-1.5mm
  • Fire Rating A2-s1,d0 to B-s1,d0
  • Profile Depth 15-50mm
  • Coating Thickness 20-35μm
  • Thermal Expansion 11-23 μm/m·°C
  • Wind Load Resistance Up to 3.0 kPa
Standards
ISO 9001, ISO 14001, EN 14509, ASTM E283, DIN 18807
