Sandwich steel panels are composite panels made up of two thin sheets of steel, called skins, which are bonded to a thicker core material. The core material can be made of a variety of materials, such as polyurethane foam, mineral wool, or polystyrene, and acts as an insulator and structural support.

Sandwich steel panels are commonly used in the construction industry for a variety of applications, they are often used for the exterior cladding of buildings due to their durability, weather resistance, and aesthetic appeal. The insulating properties of sandwich steel panels make them ideal for use in the construction of cold storage facilities, such as refrigerated warehouses. Sandwich steel panels can be used to create partition walls within buildings, providing both structural support and insulation. These panels can be used as roofing materials for commercial and industrial buildings.
