Detail Information
Sandwich Panels for Roof & Wall | Fanda
Sandwich panels are manufactured with high-quality color steel sheets as both facings and a core layer of polyurethane (PU), EPS foam, or rock wool — formed through a one-step composite process. The panels combine thermal insulation, fire resistance, moisture protection, and aesthetics. Lightweight, high-strength, and fast to install — ideal for roofing and wall cladding in industrial plants, warehouses, cold storage, clean workshops, temporary buildings, and residential projects. Core thickness: 50–200mm, steel facing thickness: 0.4–0.7mm.
