What is the sandwich panel?

The sandwich panel is composed of two layers of molded metal panels (or panels of other materials) and a polymer thermal insulation inner core foamed and cured directly in the middle of the panel, which is easy to install, lightweight, and efficient. The filling system also uses closed-cell molecular structure, which can prevent the condensation of water vapor. Sandwich panel is a common product in the current construction materials, not only can be very good flame retardant and sound insulation but also environmentally friendly and efficient.

What are the characteristics of sandwich panels?

1. Light weight: The sandwich panel weighs less than 24kg per square meter, which can fully reduce the structure cost.

2. Fast installation:The characteristics of the sandwich panel are light weight, plug-in, installation and free cutting, which determines the simplicity of installation, which can improve the efficiency and save the construction period.

3.  Fire prevention: The surface materials and insulation materials of the sandwich panel are non-combustible or non-combustible materials, which can meet the requirements of fire prevention regulations.

4. Fire resistance: Sandwich panels treated with special coatings are guaranteed for up to 10-15 years. Afterwards, anti-corrosion coatings are sprayed every ten years, and the board life is more than 35 years.

5. Beautiful: The clear lines of the sandwich panel are up to dozens of colors, which can meet the needs of any style of building

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 the sandwich panel can reach 40-50 dB, which is a very effective sound insulation material.

8.Strong plasticity: The sandwich panel can be cut arbitrarily, enough to meet the needs of special design.

9.High strength: high-strength steel plate is used as the base material, the tensile strength is 5600 (kg/cm2), coupled with the most advanced design and roll forming, it has excellent structural characteristics.
