The sandwich panel can be divided into two types: metal panel and non-metal panel. The metal panel is easy to process and can be made into various shapes. However, in some cases, the non-metal panel has a role that the metal panel can not, such as corrosion resistance and impact resistance.
Characteristics of sandwich panel:
1. The light weight per square meter is less than 24kg, which can fully reduce the structural cost.
2. The features of quick installation, light weight, plug-in, installation and free cutting determine the convenience of installation and save the construction period.
3. Fire protection: the surface materials and thermal insulation materials of color steel composite cored plate are non combustible or non combustible materials, which can meet the requirements of fire protection specifications.
4. Fire resistant, the color steel plate treated by coating can be kept fresh for 10-15 years. After that, the anti-corrosion coating is sprayed every ten years, and the service life of the plate can reach more than 35 years.
5. Beautiful, the clear lines of profiled steel plate can be up to dozens of colors, which can meet the needs of any style of buildings
6. Thermal insulation commonly used thermal insulation materials include rock wool, glass fiber wool, polystyrene, polyurethane, etc., with low thermal conductivity and good thermal insulation effect.
7. Environmental protection and noise prevention, the sound insulation strength of composite board can reach 40-50 dB, which is a very effective sound insulation material
8. Plastic strong pressure steel plate can be cut at will to meet the needs of design
9. High strength: the high-strength steel plate is used as the base material, and the tensile strength is 5600 (kg / cm2). In addition, the advanced design and roll forming have good structural characteristics.
