| Plywood | Rotary-cut or sliced wood veneers | Veneers are dried, assembled with alternating grain directions, bonded, hot-pressed, trimmed, sanded, and graded. | 3–25 mm | Furniture, cabinetry, interior construction, packaging, and concrete formwork. | Number of plies, veneer defects, core gaps, bonding strength, thickness tolerance, moisture content, and formaldehyde emission. |
| Medium-Density Fibreboard (MDF) | Refined wood fibres, wax, and resin | Wood is chipped, refined into fibres, blended with additives, formed into a mat, hot-pressed, cooled, sanded, and cut. | 2.5–30 mm | Painted furniture, cabinet components, moulded doors, wall panels, and routed decorative parts. | Density profile, surface smoothness, internal bond strength, screw-holding capacity, thickness swelling, and emission level. |
| Particleboard | Wood chips, shavings, and recycled wood particles | Particles are screened by size, dried, resin-coated, formed into layers, hot-pressed, cooled, sanded, and finished. | 6–40 mm | Ready-to-assemble furniture, shelving, office furniture, and laminated panels. | Face and core particle structure, internal bond, bending strength, screw withdrawal, thickness swelling, and edge integrity. |
| Oriented Strand Board (OSB) | Long, thin wood strands | Strands are dried, coated with resin, oriented in cross-directional layers, hot-pressed, trimmed, and graded. | 6–25 mm | Structural sheathing, flooring substrates, roof decking, packaging, and furniture components. | Strand orientation, bending strength, dimensional stability, internal bond, edge quality, moisture resistance, and surface defects. |
| Laminated Veneer Lumber (LVL) | Thin veneers with predominantly parallel grain | Veneers are dried, graded, bonded with aligned grain, continuously or batch pressed, sawn, and strength-graded. | Typically 25–75 mm | Beams, headers, furniture components, door cores, pallets, and engineered structural parts. | Veneer quality, grain alignment, glue-line performance, bending strength, modulus of elasticity, and dimensional accuracy. |
| Finger-Jointed Board | Solid-wood strips or plantation timber | Defects are removed, strips are finger-jointed, edge-glued or laminated, sanded, and inspected. | 12–30 mm | Furniture panels, shelving, tabletops, doors, and interior joinery. | Wood species, moisture content, joint strength, knot and resin-pocket limits, flatness, glue-line appearance, and surface grade. |
