What is color steel sandwich panel? What are its basic characteristics?

Color steel sandwich panel is a common product in the current building materials, not only can be very good flame retardant and sound insulation but also environmentally friendly and efficient. The color steel sandwich panel is made by pressing two upper and lower metal panels and a middle polymer heat insulation inner core. It has the characteristics of easy installation, light weight, environmental protection and high efficiency. And the closed-cell molecular structure used in the filling system can prevent the condensation of water vapor.
The color steel sandwich panel not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials. Color steel sandwich panel is an emerging material that is respected in today's world. With the advancement of science and technology, the enhancement of environmental awareness, and the improvement of people's living standards, the color steel sandwich panel activity room has increasingly shown that its strong vitality and broad market prospects are affected by construction, household appliances, electromechanics, transportation, and indoor. Favorable for decoration, office appliances and other industries.
The cores used for color steel sandwich panels are mainly phenolic foam, polystyrene, extruded polystyrene, rigid polyurethane, tripolyester, and rock wool, etc., and phenolic foam has excellent fire insulation performance and is irreplaceable by other materials For example, the thermal insulation effect of phenolic foam is more than twice that of polystyrene, and the fire resistance is also higher than that of polyurethane. When polyurethane burns, it will release dense smoke containing hydrogen cyanide.
Basic characteristics of color steel sandwich panel:
1. Oxygen index: (OI) 32.0.
2. Flexible and fast installation: the construction period can be shortened by more than 41%.
3. Thermal insulation: thermal conductivity of core material: λ<=0.041w/mk.
4. Light-weight color steel sandwich panel: 10-14 kg/m2, equivalent to 1/30 of the brick wall.
5. Bright color: no need for surface decoration, the preservation period of the colorful galvanized steel plate is 12-15 years.　　
6. High strength: It can be used as the ceiling's envelope structure and plate bearing, bending and compression; general houses do not need beams and columns.
