A skateboard structure is provided which is formed of a top piece and a bottom piece, the pieces being formed of appropriate injection molded plastic material, such as polypropylene, polyethylene, polycarbonate, “Plexiglass”, or other plastic material which is susceptible to injection molding; or aluminum casting or compression molded fiberglass; or any other material which may be molded or cast. The inner surface of each piece is formed with a lattice-work of integral webs, so that when the pieces are fitted together they define a reinforcing honeycomb-like core.
