Color‑steel sandwich panels are high‑performance building materials composed of two metal (or non‑metal) face sheets bonded to a core of polymeric insulation. They combine structural strength with excellent thermal insulation and heat‑retention properties. The face sheet thickness typically ranges from 0.2 mm to 1.0 mm, while the core thickness can be selected between 50 mm and 250 mm. Common effective panel widths are 1,000 mm and 1,200 mm. Depending on the core material, these panels can be categorized into types such as expanded polystyrene (EPS), extruded polystyrene (XPS), polyurethane (PU), rock wool, and phenolic foam; among them, phenolic foam stands out for its superior fire resistance and thermal performance. Integrating load‑bearing capacity, thermal insulation, fire protection, and waterproofing into a single unit, these panels offer rapid installation and eliminate the need for secondary finishing. They are widely used in industrial plants, warehouses, gymnasiums, cleanrooms, and prefabricated structures, making them an environmentally friendly modern building material with outstanding overall performance.
