Frequently Asked Questions about China Polyurethane Sandwich Panel Manufacturer
What is the typical lifespan of polyurethane sandwich panels
Polyurethane sandwich panels from reliable Chinese manufacturers like Shanghe typically last 25 to 30 years under normal conditions. Their durable metal facings (steel or aluminum) combined with the high-density polyurethane foam core ensure long-term resistance to weather, corrosion, and wear. Proper installation and routine maintenance can extend the panel’s functional life even further, making them a smart, lasting investment for construction and insulation needs.
Are these polyurethane sandwich panels fire-resistant or fire-retardant
Our panels feature fire-retardant polyurethane cores that comply with international fire safety standards including ASTM, EN, and GB. While polyurethane is combustible, the panels are formulated to slow down fire spread and resist ignition. The metal outer layers add another barrier to fire, improving overall safety. Always refer to specific fire rating certifications for your project requirements.
Can panels be color customized
Yes, the outer steel or aluminum layers can be customized with a wide range of colors and finishes. Common coatings include PVDF, PE, and HDP, which provide excellent durability and color retention even under harsh outdoor conditions. Color customization helps meet aesthetic preferences and branding, making the panels suitable for various architectural designs in the U.S. market.
What are the maintenance requirements
Polyurethane sandwich panels require minimal maintenance compared to traditional construction materials. Regular inspection for dents, scratches, or damage to the outer coating is recommended. Cleaning with mild detergent and water keeps the surface looking new and helps prevent buildup of dirt or contaminants. Avoid harsh chemicals or abrasive tools that can damage the protective coating.
