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.
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.
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.
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.
Rockwool sandwich panel and its manufacturing process is one the most advanced inventions, which in the factory automation equipment, rock wool and steel into a whole, thus changing the way of the rock wool plate before the compound required site , under the premise that meet the requirements of the building thermal insulation, sound insu1
