PU/PIR sandwich panel is a high-performance building material that uses PU or PIR as the core material, with high-quality prepainted steel sheets as the surface material.The foamed PU or PIR is mixed instantaneously by high pressure or low pressure foaming machine in accordance with a certain proportion, and then evenly poured between the upper and lower layers, and then
laminated foaming is formed.

| Thermal insulation | Thermal conductivity 0.019-0.024W/mK, excellent thermal insulation performance | |
| Fire rating | B3 | B1 superior to general polyurethane, can achieve a higher fire rating |
| Density | 40kg/m3 | 40-45kg/m3 |
| Hydrophobicity | >98% | >98% |
| Aplication | Industrial plant, logistics storage, integrated housing, etc | Oil refinery, chemical plant, ethylene, chemical fertilizer and construction insulation |
ROOF PANEL SYSTEM
Screw connected,roof panels are overapped tightly;The unique capillarygroove design effectively avoids rainwater seepage and cold bridge phenom-enon;The heat preservation effects of buildings are ensured and the buildingcosts of customers are significantly decreased as well. The minimum roofpitch maybe 3%.
WALL PANEL SYSTEM
The design of the wall panels allows for tight and secure joints, minimizing air leakage and enhancing the overall energy efficiency of the building. Further-more, polyurethane sandwich wall panels can be customized to meet specific design requirements, such as varying thicknesses, colors, and other specificationsCOLOR STEEL PLATE OF SANDWICH PANEI
Color steel plate is a cold-rolled steel plate or galvanized steel plate as the substrate.After surface pretreatment, coated with polyester paint, fluorocarbon paint and other organic coatings, and then baked and cooled to make the plate. It has good corrosion resistance and weather resistance, high strength and toughness, and can resist strong wind pressure and vibration to ensure the stability and safety of the building structure.
The base metals of prepainted steel plate for buildings include:hot-dip Zinc, hot-dip Al-Zinc, and hot-dip Zn-Al-Mg coated base metals.
| Type of base metal | Application/Zinc Content(both sides) | |
| Normal use | Application in highly corrosive environment (both sides) | |
| Hot-dip Zinc | 180g/m2 | - |
| Hot-dip Al-Zinc | 100g/m2 | 150g/m2 |
| Hot-dip Zn-Al-Mg | 100g/m2 | 150g/m2 |
