LVL Beam (Laminated Veneer Lumber) is an engineered wood product made from layers of 3 mm thick birch or softwood veneer, glued with the grain parallel. Bending strength up to 48 MPa — 1.5–2 times higher than solid wood. Element lengths up to 18 m. Factory precision dimensions. Applications: I-beams, rafter systems, purlins and girders, multi-story timber building frames. Complies with EN 14374 and GOST R 56706-2015. Russian manufacturers (Ultralam, etc.) ensure export supplies. Competes with CLT (cross-laminated timber) and steel beams. LVL production: peeling 3 mm veneer → drying → sorting → application of phenol-formaldehyde glue → parallel layering → hot pressing → trimming → profiling. Advantages over solid wood: bending strength 1.5–2 times higher, modulus of elasticity 14,000 MPa (solid wood — 10,000 MPa), factory precision dimensions, lengths up to 18 m without splicing, no knots or defects. Cross-section: from 45×200 to 75×600 mm. Application in I-beams: LVL flange + OSB/plywood web — lightweight flooring with spans up to 12 m without intermediate supports. Russian manufacturers: Ultralam (Torzhok), Talion Terra (Tver). Export: Europe, Middle East, CIS. Export documentation: ETA, CE, certificate of conformity. LVL fire resistance: charring rate 0.7 mm/min — same as solid wood. R30 for 45×200 mm cross-section.
