Hemaokang Steel (Shandong) Co., Ltd., established in 2025 with an annual export value of US$50 million to US$100 million, is proud to offer our premium Metal Exterior Wall Sandwich Panel. As a trusted manufacturer with ISO9001 certification and a global presence spanning North America, South America, Europe, Asia, Africa, and Oceania, we combine rigorous quality control with innovative production. This panel is designed to meet the highest standards of durability and thermal efficiency, providing free samples and full technical support to ensure your project's success. Our product is crafted from standard-compliant materials, delivering exceptional performance for modern building exteriors.
Each panel features a robust metal outer layer (galvanized steel or aluminum alloy) bonded to a high-performance insulation core – available in Polyurethane (PU), Expanded Polystyrene (EPS), or Rockwool – offering superior thermal insulation, soundproofing, and fire resistance. The sandwich structure ensures excellent structural integrity and long service life, even in harsh climates. With our free sample program, you can test the material firsthand, and our dedicated technical team provides guidance on installation, customization, and compliance.
Key Features and Technical Specifications
- High Thermal Efficiency – The insulation core reduces heat transfer, lowering energy consumption for heating and cooling by up to 40%.
- Fire-Resistant Options – Choose from Class A or B rated cores (Rockwool or PU with additives) to meet local fire safety codes.
- Weather & Corrosion Resistance – The metal surface is treated with anti-corrosion coating, resistant to UV, rain, and salt spray, ensuring minimal maintenance over 20+ years.
- Lightweight & Easy Installation – Panels weigh only 10–20 kg/m², reducing structural load; interlocking joint system allows fast, leak-proof assembly.
- Sound Insulation – Achieve up to 30 dB noise reduction, ideal for industrial or commercial buildings near noisy environments.
- Design Flexibility – Available in a wide range of colors, finishes (plain, embossed, stucco), and custom sizes to match architectural aesthetics.
