Sandwich panels can be categorized into various types based on their core materials. For instance, rock wool sandwich panels utilize medium-to-high-density rock wool as the core, with galvanized or color-coated steel sheets as the outer layers; these are bonded together through heat and pressure using automated forming machinery, offering excellent thermal insulation properties. Polyurethane (PU) sandwich panels, which feature a polyurethane core and color-coated steel facings, also provide superior thermal insulation.
Additionally, magnesium oxysulfate (MOS) sandwich panels-a type of advanced fire-resistant material-incorporate a core structured into a honeycomb-like configuration. These panels offer a smooth surface, ensure high-quality installation, and exhibit high overall structural strength, excellent flexural performance, and robust load-bearing capacity.
