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.
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.
Polyurethane Sandwich Panel also called PU Sandwich Panel, the up & down surface of this panel is Galvanized & Pre-painted steel sheets, core material is 5 components Polyurethane glue, it is formed by heating, foaming & laminating.
C channel is made of galvanized steel strips by the method of cold-bending formed.The surface treatment are galvanized or bare. It has many advantages compared with traditional structural steel, such as light weight, excellent performance cross-section, high-strength and so on.
Z steel channel is made of galvanized steel strips by the method of cold-bending formed.The surface treatment are galvanized or bare. It has many advantages compared with traditional structural steel, such as light weight, excellent performance cross-section, high-strength and so on
The sandwich panels can be used in large industrial plants,warehouses,supermarkets, hospitals, stadiums, cold storage, activities room, buildings plus layer, clean workshop and heat insulation fire place.
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
