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.
Steel purlin is usually made of cold-formed steel that is thin enough to put screws through. Cold-formed steel is made by rolling or pressing thin sheets of steel into the desired shape. Usually in "C" shape or "Z" shape. Purlins are most commonly used in Metal Building Systems, where Z-shapes are utilized in a manner that allows flexural continuit1
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 is the top grade new building material with thermal insulation, load-bearing, fireproof, low thermal conductivity, easy installation, rich colors, beautiful appearance and etc.
