Particleboard Single layer (homogeneous) 5-layer 3-layer Graduated non-structural panel product uses waste particles from other processes surface is smooth but edges are not used mostly for industrial purposes
Medium Density Fiberboard (MDF) non-structural panel product uses mechanically produced wood fibres superior machinability to particleboard markets are growing rapidly
Plywood Crossband Grain direction Core Face structural panel product uses high quality softwood veneers manufactured in 4x8ft sheets market is steady or declining
Canadian Wood Council Plywood
Oriented Strand Board uses flakes or strands (approx. 20x100x1mm) aspen, poplar, pine, mixed hardwoods used produced as large panels (up to 12x24ft) structural panel as replacement for softwood plywood market is growing rapidly

Laminated Veneer Lumber (LVL) veneers glued with grain running parallel to each other veneers graded prior to assembly used on flat or on edge used as I-beam flanges, beams and joists
Trus Joist Laminated Veneer Lumber
Oriented Strand Lumber (OSL) uses long strands of wood wide variety of dimensions possible Parallam, 2.3mx1cm veneers, high-end structural uses TimberStrand, 30cmx2cm flakes, window frames, door stock, wall studs
