Sandwich panels are cost-efficient prefabricated elements that consists of an inner insulation core between two color-coated steel sheet layers. The insulating core can be mineral wool or polyisocyanurate.In addition to sandwich panels, we offers a wide range of steel construction materials and tools needed for their installation.
The up & down surface of this rockwool panel is Galvanized & Pre-painted steel sheets, core material is 5 components rockwool glue, it is formed by heating, foaming & laminating.
A sandwich panel is one structure made of three layers of material: low density core inserted material in between two relatively thin steel skin layers.
PU sandwich panel performance full as the unique properties of PU material, with high effect for water-resistance, thermal insulation, acoustic insulation and other aspects.
