PU Sandwich Panels | Insulated Roof & Wall Panels for Steel Warehouses

Bingfa Steel Structure provides PU sandwich panels to meet industrial requirements, particularly steel warehouses, workshops, and commercial buildings. These panels are major products for worldwide projects (exports to Canada, Australia, Russia and more than 50 countries); they provide energy efficiency and durability with quick installation for your structural requirements.

PU Sandwich Panels& Advantages

Superior Thermal Insulation：PU foam core has low thermal conductivity (≤0.024 W/(m·K)), reducing heating/cooling costs for warehouses by 30-40% (critical for clients in extreme climates).
Long Durability：With galvanized steel outer layers and anti-corrosion coating, our panels have a 50+ year lifespan—matching the service life of our steel warehouses.
Fast Installation：Lightweight (15-20 kg/m²) and pre-cut to size, reducing on-site installation time by 50% (ideal for overseas projects with tight schedules).
Customization：We offer panels in thicknesses (50-200mm)、colors (RAL standard) and sizes—perfect for matching your steel warehouse design.
