Welcome to Hemaokang Steel (Shandong) Co., Ltd. As a trusted manufacturer with over 20 years of industry experience (established 2025, but with a legacy of expertise), we are proud to present our Metal Sandwich Exterior Wall Panel with 100mm PIR Core and 0.5mm Anti-Corrosion Aluminum — specifically engineered for cold storage buildings. This panel combines exceptional thermal insulation with robust exterior protection, ensuring energy efficiency and long-term durability in demanding environments. Whether you are constructing a new cold storage facility or upgrading existing walls, our solution delivers reliable performance backed by our ISO9001-certified production processes.
Our panels are designed to meet the rigorous requirements of temperature-controlled environments. The 100mm thick PIR (Polyisocyanurate) core provides outstanding thermal resistance, minimizing heat transfer and reducing operational costs. The 0.5mm aluminum facing, treated with anti-corrosion coating, offers superior weather resistance and a sleek appearance. With an annual export value of US$50-100 million and a presence in over 15 global markets, Hemaokang Steel ensures consistent quality and timely delivery.
Key Features & Benefits
- Superior Thermal Insulation: PIR core with a thermal conductivity of ≤0.022 W/m·K maintains stable interior temperatures, reducing energy consumption by up to 30% compared to traditional materials.
- Anti-Corrosion Aluminum Facing: 0.5mm thick aluminum sheets with a durable anti-corrosion coating resist rust, moisture, and chemical exposure, ensuring a long service life even in humid or saline environments.
- Lightweight yet Strong: The sandwich structure provides high strength-to-weight ratio, simplifying installation and reducing structural load.
- Fire Resistance: PIR core offers Class B or C fire performance (depending on specification), enhancing building safety.
- Easy Installation: Panels feature interlocking edges and are compatible with standard cold storage framing systems, speeding up construction.
- Customizable Dimensions: Available in various widths and lengths up to 12 meters, with options for pre-cut openings and accessories.
- Eco-Friendly: PIR is a recyclable material with low global warming potential, supporting sustainable building practices.
