Weyerhaeuser Micro-Lam LVL: Engineered Beams Built for Consistency

Micro-Lam delivers 2.0E engineered-grade performance in laminated veneer lumber that stays straight, strong, and dimensionally stable. Available in depths from 5.5 to 20 inches at the standard 1-3/4 inch thickness, with lengths spanning 1 to 60 feet.

The real advantage shows up on site. These beams can be built-up by nailing or bolting multiple plies together, eliminating the crane requirement that comes with steel alternatives. The advanced manufacturing technology produces uniform, predictable performance that resists warping, splitting, shrinking, bowing, and twisting.

Engineering That Works for Framers

That 2.0E performance rating means consistent strength across every beam. The 18-inch depth option handles serious loads for residential structural applications — headers over wide door and window openings, floor joist systems that need to span distance, and support beams for today’s open-plan designs.

The manufacturing process ensures each beam maintains its dimensional stability and supports heavy loads while staying straight and true. Contractors particularly value the Watershed overlay protection available in some regions, which provides weather resistance during construction.

Specification	Value
Grade	2.0E Engineered
Standard Thickness	1-3/4 inches
Available Depths	5.5 to 20 inches
Length Range	1 to 60 feet
Material	Laminated Veneer Lumber (LVL)

The on-site build-up capability changes the equipment equation entirely — crews can handle individual plies without heavy lifting machinery, then create the required beam strength through proper fastening. Unlike solid lumber that brings natural defects and unpredictable performance, every Micro-Lam beam delivers engineered consistency.

Distribution and Compatibility

These beams show up through multiple channels including Ring’s End, Dunn Lumber, Griff Building Supplies, Arlington Coal & Lumber, Remuda Supplies, and Forest Products Supply’s Columbus Product Line.

The product works seamlessly with other Trus Joist products like TJI joists in standard residential floor and wall systems. Technical installation notes run 32 pages through BuildSite, covering the engineering details for proper application.

For contractors choosing between engineered alternatives, Weyerhaeuser positions Parallam PSL Beams for longer spans and TimberStrand LSL Beams as additional options within their structural lumber lineup.

Frequently Asked Questions

What makes Micro-Lam different from regular lumber beams?

Micro-Lam resists warping, splitting, shrinking, bowing, and twisting through its engineered laminated veneer construction. The manufacturing process creates uniform, predictable performance that solid lumber can’t match.

Can these beams really be assembled on site?

Yes — the beams are specifically engineered for on-site build-up through nailing or bolting multiple plies together. This eliminates the heavy lifting equipment and cranes typically required for steel beam installation.

What’s the maximum span length available?

Micro-Lam beams come in lengths from 1 foot up to 60 feet.

Does Weyerhaeuser provide installation support?

Technical installation guidance comes through a 32-page document available via BuildSite, covering proper handling and application details.
