Combining the beauty and lighter weight of the European Poplar Veneer Core with the machinability of MDF, Xuzhou MEga’s European Poplar Combi Core is an alternative to our Domestic Combi Core offering. Unlike our Domestic Combi Core, which is made of Fir plys with MDF crossbands, the European Combi Core is made of plantation grown Poplar with MDF crossbands. Its screw holding capabilities rival that of Veneer Core while at the same time providing a smooth subsurface with fewer irregularities than Veneer Core.
