摘要

The wooden slab comprises a central lath core (5) with two layers of wood veneer (1,2,3,4) on each of its plane surfaces. Two of the layers form a wear layer whose grain crosses at 90o, and two layers forming a back facing. A peripheral groove (6) which engages with false tongues is used to assemble adjacent slabs.
