Lumber is a fundamental building material used in construction for framing, structural support, and finishing applications. Derived from harvested and processed timber, lumber is typically categorized as softwood (like pine, fir, or spruce) for general construction, or hardwood (like oak, maple, or teak) for cabinetry, flooring, and decorative purposes. It is available in various grades, sizes, and finishes, including rough-sawn, surfaced, pressure-treated, kiln-dried, and engineered forms such as plywood, LVL (Laminated Veneer Lumber), and glulam (Glue-Laminated Timber). Lumber is prized for its versatility, strength-to-weight ratio, workability, and natural aesthetic. In structural applications, it is commonly used for walls, floors, roofs, beams, and trusses. Sustainable forestry practices and certifications, such as FSC, are increasingly important in lumber production, ensuring the material’s environmental responsibility. Whether used in residential, commercial, or industrial projects, lumber remains a cornerstone material in modern building construction.
