Douglas Fir Glulam Beams
Glue-laminated timber beams made from Douglas fir laminations bonded with adhesives, designed for structural load-bearing applications in construction. These beams meet the definition of glulam under HTS 4418.81 as engineered structural timber products consisting of multiple wood layers glued together. Commonly used in residential and commercial building frameworks.
Southern Pine Glulam Columns
Cylindrical glue-laminated columns from southern pine species, engineered for vertical load support in timber frame buildings. Classified under HTS 4418.81 as glulam due to the glued lamination of dimensional lumber. Ideal for post-and-beam construction projects.
Western Red Cedar Glulam Roof Trusses
Pre-engineered glue-laminated roof truss components from western red cedar, laminated for high strength-to-weight ratio. Falls under HTS 4418.81.00.00 as glulam engineered structural timber, not complete joinery. Used in exposed roof applications for aesthetic and structural benefits.
Hem-Fir Glulam I-Joists
Engineered I-shaped joists with Hem-Fir glulam flanges and OSB webs, used for floor and roof framing. Classified as glulam under HTS 4418.81 due to the glued laminated flange components meeting structural timber criteria. Provides long-span capabilities in modern construction.
S-P-F Glulam Lumber
Glue-laminated lumber from Spruce-Pine-Fir mixed stands, dimensionally stable for headers and beams. HTS 4418.81 classification applies as engineered glulam with multiple laminations per definition. Common in Canadian-sourced structural applications.
Laminated Veneer Lumber (LVL) Beams
LVL beams produced by gluing thin wood veneers parallel to grain, functioning as high-strength glulam alternative. Though veneer-based, classified under HTS 4418.81 as glue-laminated structural timber when used similarly. Essential for rim board and header applications.
