Sandwich panels are construction panels formed by bonding two metal face sheets with a core material through a manufacturing process. As composite materials, sandwich panels combine the properties of both the metal sheets and the core material, offering outstanding performance. Nowadays, sandwich panel is widely used in various commercial buildings such as industrial factories, logistics warehouses, and cold storage facilities.
The metal face sheets of sandwich panel are generally made of color-coated galvanized steel, aluminum alloy, or stainless steel. The metal sheets provide excellent structural strength, good corrosion resistance, and a certain decorative appeal. The core materials mainly include polyurethane, polystyrene, or rock wool.
Depending on the core material, sandwich panels have different properties. For example, when the core material is polyurethane, the sandwich panel has excellent thermal insulation, making it ideal for cold storage. Similarly, when the core material is rock wool or fiberglass, the sandwich panel additionally offers strong fire resistance and sound insulation.
Outstanding Advantage
Sandwich panel is relatively lightweight but possess strong structural strength. Installing sandwich wall panel and roof panel can effectively reduce the load on the main structure of a building, lowering construction costs.In terms of installation, sandwich panels require shorter construction time.
They are generally designed with interlocking grooves, making installation and dismantling easier.Finally, thanks to technological advancements, the appearance of sandwich panels can be customized. Customers can design specific colors for the panels according to their needs and choose different patterns.
For example, Harbin Dong’an Building Sheets Company produces a variety of surface-treated sandwich panel products. Customers can freely choose wood grain or marble patterns, making buildings with sandwich panel more aesthetically pleasing.
