Which product is intended for high-strength beams in residential and light commercial wood frame construction?

• A. Plywood
• B. Solid lumber
• C. Laminated veneer lumber
• D. OSB

Answer: (C)

Laminated veneer lumber is designed specifically for high-strength beams in wood-frame construction. It’s made by bonding thin wood veneers with adhesive into a single, uniform member, which gives high bending strength and stiffness along with excellent dimensional stability. That uniformity means predictable performance under load, and it can be manufactured in larger depths and longer spans than solid lumber of the same weight, reducing the need for joints. This combination—great strength, stable dimensions, and the ability to span longer distances—makes LVL well suited for beams and headers in both residential and light commercial framing. Plywood and OSB are geared more toward panels for sheathing and subflooring, where their strength is directional and tied to panel behavior, not the concentrated bending strength needed for primary beams. Solid lumber is traditional and can carry high loads, but its strength varies with grain, growth rings, and moisture content, making LVL a more reliable choice when high-strength beams are required.
