Wood products are formed by bonding wood strands, veneers, lumber, and waste materials like wood shreds for structural and nonstructural applications.

Glue-laminated wood is obtained by combining numerous smaller pieces of dimensional lumber with glue.

Cross-laminated timbers are structural panels made from solid lumber, where the grain direction of the wood pieces alternates between each layer.

Nail-laminated timber is made from dimensional lumber pieces laid side by side and fastened with nails or screws.

In contrast, dowel-laminated timber follows a similar procedure but uses seasoned wooden dowels instead of metal fasteners.

Laminated strand lumber is produced using longer adhesive-coated, shredded wood strands that are given a rectangular shape and heat-cured under pressure.

Oriented strand lumber, on the other hand, is made from shorter strands following a similar process.

This process also produces parallel-strand lumber when applied to thin veneer strips arranged in a uniform parallel fashion.

Laminated veneer lumber is obtained by bonding thin sheets of wood veneer, each as wide as the final product's depth, together to form thicker, more robust structural members.
