The composition of rock wool sandwich panel mainly consists of three parts:

Surface material: The surface of rock wool sandwich panels usually uses various metal sheets as panels, such as color coated steel plates (also known as color coated steel plates), galvanized steel plates, stainless steel plates, or aluminum plates. These surface materials not only have a beautiful appearance, but also have good corrosion resistance and wind pressure resistance, which can protect the rock wool core material from external environmental erosion.

Core material: The core layer of rock wool sandwich panel is rock wool. Rock wool is an inorganic fiber material with excellent fire resistance, insulation, thermal insulation, and sound absorption properties. Rock wool core material is processed into boards with a certain thickness and density through specific processes, and filled between surface materials to provide insulation, heat preservation, and enhance structural strength.

Adhesive layer: In the manufacturing process of rock wool sandwich panels, a special adhesive is usually used to firmly bond the surface material and core material together. This adhesive needs to have good bonding performance and weather resistance to ensure that the rock wool sandwich panel will not experience delamination or cracking during long-term use.

In summary, rock wool sandwich panel is a composite board composed of three parts: surface material, core material, and bonding layer. Its surface material provides aesthetic, corrosion-resistant, and wind resistant properties; The core material rock wool provides excellent fire resistance, insulation, heat insulation, and sound absorption performance; The bonding layer ensures a strong bond between the surface and core materials. This structure makes rock wool sandwich panels have broad application prospects in fields such as construction, transportation, and machinery.
