Hemaokang Steel (Shandong) Co., Ltd. offers premium Exterior Building Cladding PU Metal Wall Panels designed specifically for cold storage applications. These panels combine exceptional waterproofing and thermal insulation properties, ensuring energy efficiency and durability for your facility. As a trusted manufacturer established in 2025 with annual export value exceeding US$ 50 million, we deliver high-quality products backed by ISO9001 certification. Our panels are widely used across North America, South America, Europe, Asia, and other global markets.
Our PU metal wall panels are engineered with polyurethane foam core sandwiched between high-strength metal sheets, providing outstanding insulation performance. The closed-cell structure of PU foam prevents moisture ingress, while the metal surface offers superior weather resistance. Below are key features and technical specifications:
- Superior Thermal Insulation: Polyurethane core with thermal conductivity ≤0.024 W/m·K, significantly reducing energy costs for cold storage.
- Excellent Waterproof Performance: Continuous sealing structure prevents water penetration, ideal for exterior cladding.
- High Structural Strength: Metal sheets (color steel or galvalume) provide rigidity and impact resistance.
- Fire Resistance: Available with B1 (flame retardant) or B2 grade upon request.
- Lightweight & Easy Installation: Standard panel weight approx. 10-15 kg/m², with simple tongue-and-groove joint system.
- Corrosion Resistant: Anti-corrosion coating on metal sheets ensures long service life even in harsh environments.
- Customizable Dimensions: Thickness from 50mm to 200mm, width options 1000mm/1150mm/1200mm, length up to 12 meters.
- Aesthetic Versatility: Available in multiple RAL colors to match building design requirements.
- Sound Insulation: Effective noise reduction, suitable for noise-sensitive areas.
