As a manufacturer from Hemaokang Steel (Shandong) Co., Ltd., we take pride in supplying high-performance Metal Polyurethane Boards that combine structural integrity with advanced thermal insulation. Our 100mm PU core panel is engineered to meet the growing demand for fire-safe and energy-efficient building materials across diverse industries. This insulation sheet features a robust 0.6mm aluminum zinc coated steel surface on both sides, ensuring long-term durability against corrosion, weathering, and mechanical stress. Built with an A2 fireproof polyurethane core, this product delivers reliable protection and outstanding thermal performance for roofs, walls, cold storage facilities, and modular buildings.
At our facility in Liaocheng, Shandong, we combine modern production methods with strict quality control to offer consistently uniform panels with smooth surfaces and precise dimensions. Each board is manufactured to meet both practical and aesthetic requirements, making it suitable for new construction and renovation projects alike. Whether you need a single container load or ongoing supply for large-scale projects, our team ensures on-time delivery from Qingdao port to clients across North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and the domestic Chinese market.
Key Product Features
- A2 Fireproof Core: The polyurethane core is formulated with flame-retardant additives, providing excellent fire resistance and limiting flame spread. It helps meet strict building safety codes for commercial and industrial applications.
- 100mm Thick Insulation: This panel thickness offers superior thermal insulation, significantly reducing heating and cooling loads. It is ideal for environments that require stable indoor temperatures and energy conservation.
- 0.6mm Aluminum Zinc Coated Steel: Both faces are made of high-strength steel with an aluminum-zinc alloy coating, which provides excellent corrosion resistance, long service life, and low maintenance requirements.
- Structural Stiffness: The metal faces and rigid PU core work together to form a strong sandwich panel that withstands wind loads, impact, and everyday wear. It is suitable for wall cladding, roofing, and partition systems.
- Lightweight Design: Despite its high strength, the panel is relatively lightweight compared to traditional building materials. This reduces the load on the building frame and simplifies handling and installation.
- Moisture Resistance: Polyurethane foam has closed-cell structure, which minimizes water absorption and prevents the growth of mold or mildew. This makes the panel suitable for humid or wet environments.
- Easy Installation: The panels are designed with interlocking edges or plain edges (customizable) to allow quick and secure fixing. Construction time and labor costs are significantly reduced.
- Environmentally Friendly: PU foam is free of HCFC and CFC, making it an environmentally responsible insulation choice. The panel contributes to green building certifications and sustainable design.

Frequently Asked Questions
Q: What is the lead time for production?
A: Our standard production lead time is 10–15 days after deposit confirmation, depending on order quantity and customization requirements. We can also arrange express production for urgent orders.
Q: Do you provide custom colors and lengths?
A: Yes, we offer a wide range of color options and can cut panels to your specific lengths. Please share your project drawings or specifications, and we will confirm the feasibility.
Q: How does the A2 fireproof core differ from standard PU foam?
A: A2 grade means the core material has a limited contribution to fire, with higher flame-retardant performance. It can help reduce fire spread and is acceptable for use in buildings with stricter fire safety codes.
Q: Can this panel be used outdoors?
A: Yes. The aluminum zinc coated steel face provides excellent weatherability and corrosion resistance. However, edge sealing and proper installation are important for long-term performance in harsh environments.
Q: What is the maximum panel length you can produce?
A: Our production line can manufacture panels up to 20 meters in length, depending on transportation restrictions. For export containers, common lengths are 6–12 meters for safe handling.
Q: Is the panel difficult to install?
A: No. The panels are designed for simple mechanical fixing. We provide installation instructions and can supply compatible accessories such as flashings, screws, and seals. Pre-drilling or interlocking profiles make assembly fast and efficient.
Q: Can we mix different thicknesses in one container?
A: Yes, we can combine various panel thicknesses, colors, and finishes in a single shipment as long as the total volume fits within the container capacity. Please contact us for a tailored loading plan.
Q: How is the panel packed for export?
A: Panels are stacked with protective film and steel strapping, then covered with waterproof paper or wrapped in a protective sheet. Inner packaging is reinforced to prevent scratching and damage during ocean freight.
