Sawn Lumber

All structural wood is divided into sawn lumber and engineered wood.  The sawn lumber,  is produced in various saw mills by simply sawing tree logs into structural wood members. Structural wood members are classified as dimension lumber, beams and stringers, post and timbers and decking.

The engineered wood is a material manufactured from sawn lumber and typically contains some type of adhesive used to bond material together. Most popular examples of engineered wood are: plywood, oriented strand board (OSB), I-joists, Laminated Veneer Lumber (LVL), glued laminated timber (Glulam) and one of the latest additions cross laminated timber (CLT).
