Hemaokang Steel (Shandong) Co., Ltd., established in 2025 with an annual export value of US$50-100 million and a dedicated team of 51-100 employees, proudly presents our 60mm Thick Polyurethane Core Metal Wall Panel. As a professional manufacturer based in Liaocheng, Shandong, China, we combine advanced production technology with rigorous quality control to deliver exterior waterproof insulated panels that meet international standards. This panel is engineered for superior thermal insulation, structural strength, and long-term durability, making it an ideal choice for commercial, industrial, and residential buildings seeking energy efficiency and weather resistance.
Our 60mm polyurethane core metal wall panel is a sandwich structure consisting of two high-strength metal skins (galvanized steel, aluminum, or color-coated steel) bonded to a rigid polyurethane foam core. The 60mm thickness provides excellent insulation performance while maintaining a competitive weight. The panel is fully waterproof due to its seamless construction and interlocking edges, ensuring no moisture ingress. Below are key technical specifications:
| Specification | Detail |
| Panel Thickness | 60 mm |
| Core Density | 38-45 kg/m³ (customizable) |
| Metal Skin Thickness | 0.4-0.8 mm |
| Thermal Conductivity (λ) | 0.022-0.028 W/m·K |
| Burning Class | B1/B2 (depending on additives) |
| Water Absorption | ≤2% by volume |
| Compressive Strength | ≥150 kPa |
| Service Temperature | -50°C to +120°C |
Key features and benefits of our 60mm PU core panel:
- Exceptional Thermal Insulation: The polyurethane foam core has one of the lowest thermal conductivity values among insulation materials, helping reduce heating and cooling costs by up to 40% compared to traditional walls.
- Waterproof and Moisture Resistant: Closed-cell PU foam inherently resists water absorption. The panel's tongue-and-groove joints and factory-applied sealants ensure a weathertight envelope.
- Structural Integrity: The metal skins provide rigidity and impact resistance, while the foam core adds shear strength. Panels can withstand wind loads and minor impacts without deformation.
- Lightweight and Easy to Install: Despite 60mm thickness, the panel weighs only about 10-14 kg/m², reducing structural load and enabling faster installation with fewer labor costs.
- Versatile Surface Finish: Available in various colors (RAL standard) and surface textures (smooth, embossed, stone-coated). Suitable for modern architectural aesthetics.
- Environmentally Safe: PU foam is CFC/HCFC-free, and the panels are fully recyclable at end of life. Contributes to green building certifications like LEED.
- Fire Retardant Options: With special additives, the panel can achieve B1 (difficult-to-ignite) classification, meeting safety codes for commercial buildings.
Application areas:
- Exterior walls of cold storage rooms, warehouses, and factories
- Commercial building cladding (hotels, office buildings, shopping malls)
- Residential exterior insulation systems
- Agricultural structures (poultry houses, greenhouses)
- Modular houses and temporary shelters

Frequently Asked Questions (FAQ):
-
Q: What is the maximum panel length you can produce?
A: Standard lengths range from 2000mm to 6000mm. Custom lengths up to 12000mm are available upon request with special handling. -
Q: Can these panels be cut on site?
A: Yes, they can be cut using standard metal-cutting tools (e.g., circular saw with carbide blade). We recommend sealing cut edges with a compatible sealant to maintain waterproof integrity. -
Q: Do you provide installation guides or technical support?
A: Absolutely. We supply detailed installation manuals and offer online technical support. For large projects, we can arrange on-site training through our partners. -
Q: How do you ensure the panels are waterproof at the joints?
A: Our panels feature a lap joint or tongue-and-groove system. During installation, a sealant is applied to the joint, and optional rubber gaskets can be integrated for enhanced watertightness. -
Q: Are these panels suitable for seismic zones?
A: Yes. The metal facings and rigid foam core provide good ductility. The panels can be designed with flexible connections to accommodate seismic movements. Please consult our engineers for specific requirements. -
Q: What is the warranty period for your panels?
A: Standard warranty is 10 years against manufacturing defects. Extended warranties are negotiable based on project size and conditions. -
Q: Can you produce panels with a specific fire rating?
A: Yes, we can add flame retardants to the PU foam to achieve B1 (European class) or other local fire ratings. Please provide your target classification so we can customize accordingly. -
Q: How do you package the panels for export?
A: Panels are packed in wooden crates or steel frames with protective plastic wrap to prevent moisture and damage. Standard sea-worthy packaging meets ISPM 15 requirements.
