VERSA-LAM LVL delivers 2800-2900 psi bending strength with 2.0 million psi modulus of elasticity — numbers that make dimensional lumber look like kindling. This isn’t marketing fluff. It’s engineered lumber that handles the loads Montana construction demands without the surprises that come with solid-sawn beams.
The confusion starts with branding. Weyerhaeuser makes MicroLam LVL. Boise Cascade makes VERSA-LAM LVL. Both hit similar performance specs, but the 2800Fb rating specifically belongs to Boise Cascade’s VERSA-LAM 2.0E product, while Weyerhaeuser’s 2.0E MicroLam typically rates at 2900Fb. Contractors use the names interchangeably because the products perform nearly identically on the jobsite.
The Numbers That Matter
The 1-3/4” x 11-7/8” VERSA-LAM LVL 2.0E exemplifies what engineered lumber brings to the table:
| Specification | Value | Source |
|---|---|---|
| Bending Stress (Fb) | 2800-2900 psi | Manufacturer |
| Modulus of Elasticity (E) | 2.0 x 10^6 psi | Manufacturer |
| Horizontal Shear (Fv) | 285-290 psi | Manufacturer |
| Compression Perpendicular (Fc⊥) | 750 psi | Manufacturer |
| Weight per Linear Foot | ~5.5-6.0 lbs | Manufacturer |
| Specific Gravity | 0.50 | Manufacturer |
The broader product line includes multiple grades — 1.5E, 1.8E, and 2.1E — each engineered for specific load requirements. The top-end 2.1E grade pushes modulus of elasticity up to 2.1 million psi. Available widths run from 15/16” all the way to 24”, with depths matching up to 24”. That’s real flexibility for complex structural demands.
Minimum bearing requirements stay reasonable at 1-3/4” for end bearing and 3-1/2” for intermediate bearing. Standard carpentry tools handle the cutting — no need for metal-cutting equipment like you’d need with steel beams.
Why Contractors Choose LVL
The “no camber” design changes everything. Flat floors without crown calculations. No guessing about how much the beam will settle. Customer feedback consistently highlights how the dimensional stability saves time versus building headers from dimensional lumber.
Compared to standard dimensional lumber, LVL brings predictable performance without knots, splits, or the other defects that make 2x12s a gamble. Against glulam beams, VERSA-LAM delivers higher bending strength and stiffness. Steel still wins for extreme loads or very long spans, but LVL installs with standard framing tools and doesn’t require specialized labor.
Long lengths allow continuous spans — critical for Montana’s open floor plans where homeowners want great rooms without posts breaking up the space. The ability to build up members on-site reduces the heavy lifting that sends crews to the chiropractor.
Multi-ply assemblies need proper fastening — typically two rows of 16d nails at 12” on center for 2-ply beams. Follow the nailing patterns religiously. Never notch or drill without consulting the manufacturer’s hole charts. These beams are engineered to precise tolerances.
Installation Reality Check
Contractors report the weight becomes an issue in longer lengths — plan your lifting strategy before the beam arrives. Yes, it costs more than dimensional lumber upfront. But factor in the labor savings from not building up headers, the callback reduction from stable floors, and the ability to span distances that would require posts with conventional framing.
Storage matters. Keep these beams flat and off the ground until installation. Keep them dry. Made with either Southern Pine or Douglas Fir veneers bonded with exterior-grade phenol formaldehyde or isocyanate adhesives, they’ll handle jobsite conditions but weren’t designed to sit in Montana weather for months.
Compatible with TJI joists and BCI joist systems, standard framing hangers from Simpson Strong-Tie or USP, and matches standard wall framing depths like 11-7/8” for floor systems. Everything works together without custom fabrication.
Both Weyerhaeuser and Boise Cascade back their engineered wood with limited lifetime warranties when properly installed and used in dry, covered conditions. The products meet ICC-ES requirements (ESR-1387 for Weyerhaeuser MicroLam, ESR-1040 for Boise Cascade VERSA-LAM) and comply with both IBC and IRC codes.
The bottom line? VERSA-LAM LVL costs more than a stack of 2x12s but delivers engineered performance that dimensional lumber can’t match. For headers carrying serious loads, main support beams, and anywhere predictable performance beats crossed fingers, these beams earn their place on Montana jobsites.
Frequently Asked Questions
Q: What’s the actual strength rating of VERSA-LAM LVL beams?
VERSA-LAM LVL 2.0E beams are rated at 2800 psi bending stress (Fb) with a modulus of elasticity of 2.0 million psi. Weyerhaeuser’s competing MicroLam LVL 2.0E product rates slightly higher at 2900 psi, though both perform nearly identically on jobsites.
Q: Can I cut and drill VERSA-LAM beams like regular lumber?
You can cut VERSA-LAM LVL to length with standard saws, but never notch or drill without consulting the manufacturer’s hole charts. These engineered beams have precise tolerances that drilling or notching can compromise.
Q: What sizes does VERSA-LAM LVL come in?
The common 1-3/4” x 11-7/8” VERSA-LAM beam weighs about 5.5-6.0 pounds per linear foot. The broader product line offers widths from 15/16” to 24” and depths up to 24”, with multiple grades including 1.5E, 1.8E, and 2.1E for different load requirements.
Q: How do I properly connect multiple VERSA-LAM beams together?
Multi-ply VERSA-LAM assemblies require specific fastening patterns — typically two rows of 16d nails at 12 inches on center for 2-ply beams. Minimum bearing requirements are 1-3/4” for end bearing and 3-1/2” for intermediate bearing.
Q: What’s the warranty on VERSA-LAM products?
Both Weyerhaeuser and Boise Cascade offer limited lifetime warranties on their engineered lumber products when properly installed and used in dry, covered conditions. The products meet ICC-ES requirements and comply with both International Building Code (IBC) and International Residential Code (IRC).
Q: Why do contractors prefer VERSA-LAM over dimensional lumber for headers?
VERSA-LAM LVL eliminates the camber found in dimensional lumber, delivering flat floors without crown calculations, and it’s free from knots, splits, and other defects common in 2x12s. The uniform strength and dimensional stability save time versus building up headers from multiple pieces of dimensional lumber.
