Design a beam depth based on the rule of thumb for estimating the depth of manufactured beams which is to divide the span by 20. The beam may be composed of two or more widths or plies of LVL for lighter lifting, or a solid width up to 7. Once the loads acting on structural beams are calculated, the next step is to size and select the appropriate beam. (in AF&PA Design Values for Joists and Rafters #2 hem-fir = Fb @1104 psi & E @1,300,000 psi so use span table column Fb 1100). Most LVL lumber is for dry interior use, but H3 and other chemically treated laminated lumber can be used outdoors and exposed to various weather conditions. All illustrations are provided through the courtesy of the Journal of Light Construction. It is a composite product made of many thin layers of veneer that align the length of the final timber. It is a cost-effective option for many applications, but it can be very hard to find. Analytical cookies are used to understand how visitors interact with the website.

TimberStrand Header comes only in 3 widths in depths that range from 4 3/8 to 18. Because of the woods dimensional stability, inspection times are often reduced, too. 2 pine or LVL. a double 9 1/2 lvl is made by laminating of two 1 3/4 inches or 40mm thick and 9 1/2 deep LVL. For example: An 12 inches deep an LVL beam can span upto 20 feet (1212 20= 20 foot). This means trying to compare different products is often difficult, so always check with your local building department or a Structural Engineer. You can do these calculations yourself or you can use span tables. LVL beam (Laminated veneer lumber) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. Differences (5) The laminated lumber is typically available in 4-foot increments beginning at 4 and running up to 44 or 48 in length. As a result, it doesnt clear-span long distances, comes in sizes only up to 212, and select structural grades are not always available. Most interior beams need to include the roof load. It is available in thickness from 19mm (3/4 inches) to 178mm (7 inches). The second is whether or not. The required E-value does not change when you double the 26 because as you double the allowable load, you are doubling the thickness of the beam.
