Hemaokang Steel (Shandong) Co., Ltd. is proud to introduce our premium Closed Cell PU Foam Density 40kg/m³ Metal Wall Panel, engineered for superior outdoor waterproof insulation. Manufactured in our ISO9001-certified facility in Liaocheng, Shandong, this panel combines advanced polyurethane foam technology with robust metal facings to deliver exceptional thermal performance and durability. With an annual export value of US$50-100 million and a global client base spanning North America, Europe, Asia, and Oceania, we are a trusted partner for construction projects requiring reliable, energy-efficient building solutions.
Our panel’s closed-cell structure ensures minimal water absorption, making it ideal for exterior walls, roofs, cold storage, and industrial facilities. The 40 kg/m³ density strikes the perfect balance between insulation efficiency and structural integrity, reducing energy costs while withstanding harsh weather conditions. Whether you need custom dimensions or specific color coatings, our flexible production lines can meet your requirements.
Key Features & Technical Specifications
- Closed Cell Structure – Prevents moisture ingress, ensuring long-term waterproof performance even in heavy rain or snow.
- Thermal Insulation – Low thermal conductivity (typically 0.022-0.028 W/m·K) helps maintain stable indoor temperatures, reducing HVAC load.
- Lightweight yet Strong – Density of 40 kg/m³ makes panels easy to handle and install, while the metal facings add rigidity and impact resistance.
- Fire Resistance – Options available with fire-retardant PU foam (upon request), meeting various international safety standards.
- Weatherproof – Resistant to UV radiation, corrosion, and temperature extremes, suitable for outdoor applications.
- Easy Installation – Interlocking tongue-and-groove or overlapping joint systems reduce on-site labor time and costs.

Frequently Asked Questions (FAQ)
-
Q: Can I get customized panel dimensions (thickness, width, length)?
A: Yes, we offer full customization. Panel thickness can range from 50 mm to 200 mm, width from 900 mm to 1200 mm, and length up to 12 meters. Please provide your project specifications. -
Q: Is this panel suitable for direct outdoor exposure?
A: Absolutely. The closed-cell PU core and metal facings are designed for outdoor use, with excellent UV resistance and waterproofing. We recommend using appropriate sealants at joints for best results. -
Q: Does the panel have any fire rating?
A: Standard PU foam is combustible. However, we can supply panels with fire-retardant (FR) foam additives upon request, which meet Class B1 or Class A2 standards depending on the formulation. Please consult our sales team. -
Q: What is the expected lifespan of these panels?
A: With proper installation and maintenance, the panels can last 20–30 years. The metal facings are coated for corrosion resistance, and the PU foam does not degrade or settle over time. -
Q: How are the panels packed for export?
A: Panels are bundled with protective edge covers and wrapped in waterproof paper + steel strapping. Alternatively, we can use plywood crates for fragile finishes. Shipping is via container or bulk vessel. -
Q: Do you provide samples before bulk order?
A: Yes, we can send small free samples (300x300 mm) for quality evaluation. Freight charges may apply based on destination. -
Q: What payment terms do you accept?
A: We accept T/T, L/C at sight, and other negotiable terms for regular customers. A 30% deposit and 70% before shipment is standard. -
