The LVL wood beams are stamped every 4’ with the manufacturer’s name, branding logo, or product identification number and stress grade in accordance with ASTM D5456 or CSA 086. The LVL sheets are sanded smooth on all sides and then cut into widths and lengths based on market demand or special orders. LVL is also straighter and of more uniform dimensions than regular lumber, and is less likely to shrink, twist, warp, or bow. Since the layers of wood grain all run parallel to each other, LVL is similar to solid wood, but at least twice as strong. The stacks then pass into a machine that produces high heat and pressure to ensure a strong, long-lasting adhesive bond between layers. The number of sheets in the stack determines the thickness of the laminated beam. The glued sheets are then stacked with the grain running longitudinally like solid lumber not alternating longitudinally and latitudinally as with plywood. The veneer then passes through a gluing machine that applies a thin layer of waterproof adhesive. Once dried and trimmed, the sheets pass through a sander or grinder that flattens and smooths them to a consistent thickness. The veneer sheet is then dried with hot air, causing it to shrink some, and then it is trimmed to size for LVL production. The logs are debarked, pressure steamed with a mix of water vapor and chemicals for 48-hours, and then run through a veneer peeler that ‘unrolls’ the log into a continuous sheet with a thickness between 1/16” and 1/4”. It is made in a similar manner to plywood using softwood veneer logs or peelers. LVL or laminated veneer lumber was used to make propellers for aircraft in WW2 but didn’t become a construction material until the mid-1970s.
#16 LVL BEAM COST HOW TO#
Additionally, we look at how to install an LVL beam. We explain how to determine beam size and also discuss their cost.

In this article, we’ll identify what LVL beams are, their different sizes, how far they can span, and their different uses. Depending on its width, depth, and load parameters, an LVL beam can span up to 80-feet. The layers are heated, glued, and pressed together in different widths or thicknesses, and then cut to depths to meet various load requirements. After explaining what it was and the LVL beam span, I decided to give it a try, but I also wanted more information.Īn LVL or laminated veneer lumber beam is made up of thin layers of wood veneer similar to plywood. Such was a recent experience when I was looking for a beam for a renovation project. Due to its composite nature, it is much less likely than conventional lumber to warp, twist, bow, or shrink.Every time I wander through my local lumber store, I seem to encounter a new product, not that it’s all that new, just to my awareness or my location. LVL offers several advantages over typical milled lumber: Made in a factory under controlled specifications, it is stronger, straighter, and more uniform. Replace a Load-bearing Wall with a Beam Cost Costs to install a steel beam range from $1,150 to $4,600, but will vary based on the size and type of steel beam you choose and the labor needed to install it. Herein, how much does it cost to install a load bearing beam? In that case, you need something like a 12-16" GLULAM or LVL to span the 20' and can use simple 2x8-10 dimensional lumber 16"OC as floor joists. Because of transport limitations, the maximum standard length for manufactured beams is sixty feet.Īlso, what size LVL Do I need to span 20 feet? Re: 20 foot clearspan beam size Then your floor joists only need to span 8' between the wall and the "beam" (or between the beams). Measure your total span between members and ensure that it is not greater than 60 feet.

Regarding this, how far can a LVL beam span?
