Advantages of extruded sandwich panels

① The specific strength of extruded sandwich panel is high.

② The extruded sandwich panel is cheap and large, and the surface material is expensive and small, so the production cost of this product is low.

③ Reasonable selection and matching of surface and core materials can effectively meet the performance requirements of pre-designed plates.

For example, metal cladding is selected to improve the fire and water resistance of the plate, and decorative plate or plastic sheet is selected as the surface to improve its decorative effect.

Extruded sandwich panel was successfully studied in the late 1960s. At that time, it was mainly used in aircraft manufacturing, and then gradually expanded to architectural decoration, such as partition, door leaf, floor, furniture parts, refrigerator shell, etc. Subsequently, some are also produced successively, so its application range is expanding day by day. It is an important lightweight and high-strength material. The sandwich panel with extruded structure is widely used, which is referred to as extruded sandwich panel for short.
