The filler block 43 is wrapped around the outside of the first reinforcing rod 41 and the second reinforcing rod 42 and is connected between the second cardboard layer 5 and the core paper layer 1. The filler block 43 can improve the flatness of the grid surface formed by the multiple first reinforcing rods 41 and the multiple second reinforcing rods 42, and the first reinforcing rods 41 and the second reinforcing rods 42 can improve the compression and bending resistance of the core paper layer 1.

[0039] Furthermore, the protective component 3 includes an anti-corrosion layer 31 and a first aluminum plate layer 32. The anti-corrosion layer 31 is connected to the top of the first cardboard layer 2 by an adhesive.
