Weyerhaeuser 1-3/4 x 11-7/8 VERSA-LAM LVL 2.0E 2800Fb

The VERSA-LAM LVL 2.0E 2800Fb delivers a 2800 psi bending stress rating and 2.0 million psi elasticity modulus — numbers that matter when you’re spanning long distances or carrying serious loads. This engineered lumber product solves the dimensional stability problems that plague traditional lumber while maintaining workability with standard carpentry tools.

For Montana contractors dealing with open floor plans and great rooms, this LVL offers predictable performance without the warping, twisting, or shrinking that causes callbacks. At roughly 5.5-6.0 pounds per linear foot, crews can handle it without specialized equipment, yet it packs the structural punch needed for headers, beams, and floor systems.

Load Capacity and Structural Performance

The 2800 psi bending stress (Fb) rating puts this LVL well above traditional lumber. The 2.0 x 10^6 psi modulus of elasticity means minimal deflection under load. Horizontal shear capacity hits 285-290 psi, while compression perpendicular to grain reaches 750 psi.

Compared to standard 24F-V4 glulam, this LVL provides higher bending strength and stiffness. Against dimensional lumber, it’s significantly stronger and more stable — without the knots, splits, or other defects that compromise load capacity.

Dimensional Stability and Installation

The no-camber design means flat floors and walls — period. This LVL resists warping, twisting, and shrinking, eliminating the callbacks that come from lumber movement in Montana’s temperature swings.

Bearing requirements are straightforward: 1-3/4” minimum for end bearing, 3-1/2” for intermediate bearing. Multi-ply beams need specific fastening — 2 rows of 16d nails at 12” on center for 2-ply assemblies. The product works with TJI joists, BCI joist systems, and standard framing hangers from Simpson Strong-Tie or USP.

Don’t notch or drill without consulting the manufacturer’s hole charts. Store it flat and off the ground, keeping it dry until installation — basic stuff that prevents jobsite headaches.

The 11-7/8” depth matches standard floor system dimensions, making it a drop-in replacement for inferior alternatives. Available in long continuous lengths, you can span distances that would require multiple pieces of dimensional lumber.

The Bottom Line

Contractors report extremely straight material with consistent quality that saves time versus building headers from dimensional lumber. The trade-offs are honest: it’s heavy in long lengths, costs more than standard lumber, and requires following specific nailing patterns for multi-ply beams.

Both Weyerhaeuser and Boise Cascade offer limited lifetime warranties when properly installed in dry, covered conditions. The products carry ICC-ES certifications (ESR-1387 for Weyerhaeuser MicroLam, ESR-1040 for Boise Cascade VERSA-LAM) and comply with IBC and IRC requirements.

For Montana’s open floor plans and temperature extremes, this LVL delivers genuine engineering advantages over traditional alternatives. The dimensional stability alone justifies consideration for any structural application where callbacks cost real money.

Frequently Asked Questions

What’s the actual difference between 2800Fb and standard lumber? The 2800 psi bending stress rating means this LVL handles loads that would break dimensional lumber. It’s significantly stronger than 2x12 dimensional lumber and less prone to defects like knots or splits.

Can I cut this with regular tools? Yes, it cuts with standard saws. It’s lighter and easier to work with than steel while providing superior strength. Just don’t notch or drill without checking the manufacturer’s hole charts.

What are the real-world applications? Common uses include beams and headers for windows and doors, floor girders and main support beams, stair stringers, rim boards, and garage door headers.

Is there confusion about the manufacturer? Yes — the product name combines two different manufacturers. Weyerhaeuser makes MicroLam (typically 2900Fb), while Boise Cascade makes VERSA-LAM (2800Fb rating). Both are quality products with similar performance characteristics.

How does multi-ply assembly work? Connect plies using 2 rows of 16d nails at 12” on center for 2-ply assemblies. The beams can be easily built up on site to reduce heavy lifting.
