Its main advantages include:

High specific strength of the material.

② Core material is inexpensive and in high demand, while surface material is expensive and in low demand, thus making the production cost of this product relatively low.

③ Selecting and pairing surface and core materials reasonably can effectively meet the pre-designed performance requirements of the sheet material.

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 for the surface to improve the decorative effect.
