Its primary advantages include:

The板材 possess high specific strength.

② Core material is cost-effective and used in large quantities, while surface material is expensive but used in small quantities, thus making the production cost relatively low.

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

If metal cladding is chosen to enhance the fire and water resistance of the sheet material, decorative panels or thin plastic sheets can be used as the surface layer to improve its decorative effect.
