Sandwich Panels

Yes, sandwich panels can be used for both roof systems and wall cladding in steel structure buildings. Roof sandwich panels help reduce heat transfer and improve waterproof performance, while wall sandwich panels provide insulation, protection, and a professional exterior finish. They are suitable for warehouses, workshops, commercial buildings, and agricultural facilities.

Sandwich panel thickness depends on the building use, insulation requirement, local climate, and fire rating. Common thickness options include 50mm, 75mm, 100mm, 150mm, and 200mm. General warehouses may use thinner panels, while cold storage buildings, clean rooms, and high-temperature areas usually require thicker panels for better insulation performance.

Fire resistance depends on the core material. Rock wool sandwich panels provide strong fire-resistant performance and are often used in projects with higher fire safety requirements. PIR panels offer improved fire performance compared with standard PU panels. EPS panels are economical but may not be suitable for projects with strict fire protection standards.

High-quality sandwich panels can provide long service life when installed correctly and maintained properly. The durability depends on panel coating, core material, installation quality, corrosion environment, and weather exposure. For steel buildings, color-coated steel surfaces, proper sealing, and correct fasteners help improve panel lifespan and building performance.

Yes, sandwich panels can be customized by thickness, core material, steel sheet thickness, surface color, coating type, panel length, joint style, and fire rating. Custom sandwich panels are commonly used for steel warehouses, cold rooms, factories, clean rooms, poultry farms, and prefabricated buildings to match specific project requirements.
