Edensaw seattle apa product guide hdo mdo plywood murphy. googleusercontent search. consistent quality, stability mdo, also known as signboard, is an exterior grade plywood with a high quality. Like hdo, medium density overlay plywood is an exterior-type panel manufactured only with 100 percent water- resistant adhesive. regular mdo is produced with b-grade face and back veneers and c-grade inner plies.. Hdo plywood is much like mdo plywood, except that the density of the fiber surface layer is much greater. this greater strength means that hdo plywood can usually be reused several times for forming. thus the density of the surface layer is the distinguishing factor between mdo and hdo plywood..

Hdo plywood is much like mdo plywood, except that the density of the fiber surface layer is much greater. this greater strength means that hdo plywood can usually be reused several times for forming. thus the density of the surface layer is the distinguishing factor between mdo and hdo plywood..
