Polyurethane(PU)sandwiched panel is composed of 2 layers of colored steel sheets and injected hard forms of polyurethane between 2 layers which feature fireproof materials.
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.
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
