What is Micro Lam LVL?

Microllam is the brand name for a type of engineered lumber made by Weyerhauser and used for heavy structural support. Each piece of this lumber is actually composed of smaller, micro-thin layers of wood that are glued together—or laminated.

Is PSL stronger than LVL?

PSL beams are primarily used in beam and header applications where high strength is required. PSL beams can be stained or finished where an aesthetically pleasing exposed application is desired. Laminated Veneer Lumber (LVL) is a commonly available engineered product that is manufactured similarly to PSL.

How far can you span with LVL?

If you want your total span between members to be less than 60 feet, you need to measure it. The maximum length of manufactured beams is sixty feet.

What is the longest LVL?

LVL is available in lengths up to 24.4 m (80 ft), while more common lengths are 14.6 m (48 ft), 17 m (56 ft), 18.3 m (60 ft) and 20.1 m (66 ft). LVL can easily be cut to length at the jobsite.

Is LVL stronger than steel?

concentrated load in the middle of a 16′ span. It’s obvious that steel would be a far better choice–almost 9 times stronger than the LVL, even without a cover plate.

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 .

Will a LVL sag?

It is not unsafe because the LVLs will have to be seriously sagging before anything would happen. 5/8″ is just enough to disturb the finish and annoy you. You can either install a beam in the middle of the room or put in a better header.

Are LVL beams expensive?

LVL beams cost $3 to $12 per linear foot on average. LVL beams are more affordable and stronger than wood beams. They’re also fire-resistant, shrink-proof, and easy to install in long lengths.

What are the disadvantages of LVL?

Although its dimensional stability is better than solid wood, the product may result in some defect, such as warping, if it is not properly stored in the warehouse. Also, LVL requires high capital investment to have relatively low production cost.
