Hemaokang Steel (Shandong) Co., Ltd., established in 2025 and headquartered in Liaocheng, Shandong, China, is a professional manufacturer of high-quality steel building materials. With an annual export value of US$50 million – US$100 million and a dedicated team of 51–100 employees, we are committed to delivering reliable, fire-resistant wall panels for industrial projects worldwide. Our Metal Exterior Wall Sandwich Panel with 0.6mm thickness and rockwool core combines superior thermal insulation, structural strength, and exceptional fire protection, making it the ideal choice for modern industrial buildings, warehouses, and factories.
Key Features & Technical Specifications
- Fireproof Core: High-density rockwool (≥120 kg/m³) provides excellent fire resistance, achieving Class A non-combustible rating. It can withstand temperatures up to 1000°C, preventing fire spread and ensuring building safety.
- Durable Metal Facings: Both outer and inner sheets are made from 0.6mm thick galvanized or color-coated steel, offering high corrosion resistance, impact strength, and long service life (up to 25 years under normal conditions).
- Thermal Insulation: Rockwool core has a low thermal conductivity of 0.035–0.040 W/m·K, significantly reducing heat transfer. This helps maintain stable indoor temperatures, lowering HVAC energy consumption by up to 30%.
- Soundproofing: The dense fiber structure of rockwool absorbs sound, providing excellent acoustic insulation (sound reduction index up to 45 dB) – ideal for noisy industrial environments.
- Easy Installation: Panels feature a tongue-and-groove joint design, allowing quick assembly with minimal labor. Each panel covers a width of 1000mm, and lengths can be customized up to 12 meters, reducing seams and improving air tightness.
- Weather Resistance: The metal surface is treated with anti-corrosion coatings (e.g., PVDF, HDP) to withstand UV radiation, rain, snow, and temperature extremes. Suitable for use in various climates.

Frequently Asked Questions (FAQ)
-
Q: What is the fire resistance rating of this panel?
A: Our rockwool core panel achieves Class A non-combustible rating (EN 13501-1, ASTM E84). The fire resistance time (e.g., 60, 90, 120 minutes) depends on core thickness. For example, 100mm core can provide up to 2 hours fire resistance. -
Q: Can the panel be used for both walls and roofs?
A: Yes, this panel is designed primarily for exterior walls, but it can also be used for roofs (with additional structural support if needed). We recommend using specific roof panels for better water drainage. -
Q: What is the standard panel width and length?
A: Standard width is 1000mm (effective width 950mm). Length is customizable up to 12 meters. Shorter lengths are available for easier handling. -
Q: Is the panel waterproof?
A: The metal facings are waterproof, and the tongue-and-groove joint, when properly sealed with silicone or rubber gaskets, provides excellent water resistance. However, for severe weather, additional sealant is recommended. -
Q: How long does it take to install?
A: Installation is quick due to the lightweight design and interlocking joints. A typical industrial building wall can be enclosed in 1–2 weeks, depending on size and complexity. -
Q: Do you offer custom colors or surface finishes?
A: Yes, we support a wide range of RAL colors and finishes including smooth, embossed, and PVDF-coated options. Minimum order quantity may apply for custom colors. -
Q: What is the expected lifespan of the panel?
A: Under normal conditions, the panel can last 20–25 years, with the metal facings requiring minimal maintenance. The rockwool core does not degrade over time. -
Q: Do you provide samples before bulk order?
A: Yes, we can provide samples (A4 size or small panel) upon request. Shipping cost is at buyer's expense, but we can arrange for express delivery.
