Engineered Beams
Precision matters when spans get longer and loads get heavier. Capital Lumber supplies a full range of engineered wood products designed for superior strength, straightness, and dimensional stability in structural framing applications. Ideal for floor systems, headers, and long-span conditions, engineered beams help reduce deflection, improve consistency, and simplify installation. With cut-to-size options and jobsite delivery available, Capital Lumber supports builders from layout to final set.

LVL Beams (Microllam®)
High-strength beams for critical structural spans, LVLs are commonly used for headers, beams, and rim boards. Manufactured for consistency and straightness, LVLs reduce crown and shrinkage issues found in solid sawn lumber.

I-Joists (TJI®)
Lightweight framing with long-span capability, I-joists are ideal for floor systems requiring strength, stability, and quiet performance. Designed to minimize bounce and deflection, they help create flatter floors and cleaner installs.

LSL Framing (TimberStrand®)
Engineered studs and framing members with uniform performance, LSL provides predictable strength and straightness. Well-suited for applications where consistency matters, including long walls, tall openings, and engineered assemblies.

Glulam Beams (X-Beam®)
Custom-engineered beams for larger spans and exposed applications, glulams offer high load capacity with architectural flexibility. Available in custom sizes and lengths, they support both structural and visual requirements in residential and commercial builds.
Overview
Capital Lumber supplies a full range of engineered wood products (EWP) designed for superior strength, consistency, and performance in structural framing applications. These beams are ideal for floor systems, headers, and long-span applications where dimensional stability and load-bearing capacity are critical.
Our selection includes Microllam® LVL, TimberStrand® LSL, and TJI® Joists, sourced from trusted manufacturers like Weyerhaeuser and Rosboro.
