ABSTRACT:
A structural laminate having a groove impressed on its surface useful as an external siding. The laminate comprises an outer wood face veneer, the grain of which is oriented along a given direction, and at least two particle board plies, the particle board ply nearest the outer face veneer having a particle orientation along a direction perpendicular to the grain of the face veneer, the other of said particle board plies having a particle orientation along the same direction as the face veneer. The composite laminate is produced in a single pressing operation in which the groove is pressed into the outer surface during the pressing of the plies into a composite laminate.
