Is LVL stronger than wood? Laminated veneer lumber (LVL) studs can provide ultimate strength against wind and shear-loads and can be up to two and a half times stronger than standard framing lumber of the same dimension in compression and tension, which means a wood-framed house can be designed and constructed to withstand 100 mph or more .
How long are TJI joists?

These standard-size TJI® joists are readily available through your local Weyerhaeuser dealer or distributor. Offered with the flange sizes shown below, they come in lengths up to 60′ (in 1′ increments).
What is TJI framing? The dimensional stability of TJI joists help them resist warping, twisting and shrinking that can lead to squeaky floors. TJI joists are lightweight and come in long lengths, which makes them faster and easier to install than traditional framing, and saves you both time and money.
Who makes TJI joist?

How much does a 20 foot LVL beam cost? The LVL beam thickness is usually between 1.75 and 7 inches. The price for beams that fit 10 feet of space will range from $3 to $5 per linear foot, while a 20-feet span will need a beam that costs $6 to $11 per linear foot. Consult a local structural engineer to determine the best LVL beam size for your span.
How far can a 2×14 LVL span?
Due to its strength, an LVL beam can span up to 60 feet and is much stronger than traditional lumber. Generally, you can find LVL beams in 4-foot increments starting at 24 feet and going up to 44 feet long, with special orders up to 60 feet. LVL beam thickness is usually between 1 ¾ and 7 inches.
