Its primary advantages are:

The material has a high specific strength.

Core material is cost-effective and used in large quantities, while the surface material is expensive and used in smaller quantities, thus resulting in a lower production cost for this product.

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

If a metal coating is chosen to enhance the board's fire and water resistance, decorative panels or thin plastic sheets can be used for the surface to improve its decorative effect.
