The clear span depends on the dead load of wall, floor, and roof loads, the location of the beam, live loads, snow load, and the width of the load area. The distance a beam needs to span may be easy to identify, but its width and depth depend on the number of piles or supports, as well as other factors. The manufacturer’s name or logo is stamped every 4 feet on their LVL wood beams along with the beam’s stress grade and product number to meet ASTM D5456 or CSA 086 requirements. LVL wood beams are used in both hidden and visible applications for floor and ridge beams, joists and rafters, and headers and lintels. The span is also limited to the mode of transportation from the mill to the job site. Increasing to a 7” by 24” 2.1E 3100 and the span can be 60 to 80 feet depending on all variables.

However, to support typical loads, it is usually doubled or tripled for those distances.Ī 3-1/2” by 7-1/4” 2.1E 3100 LVL beam can span to 20 feet, while a 3-1/2 by 9-1/2” will do 26 feet and greater thicknesses 30 feet or more. Increasing the depth of the 1-3/4” wide beam to 14” or more and to span 30 feet or more.

A 1-3/4” by 7-1/4” (2×8) 2.1E 2800 LVL beam can span to 16 feet with a load duration of 100%, while a 9-1/2” deep one can span 20 feet, and an 11-7/8” up to 26 feet. LVL beam span varies by dimensions, stress grade, and loads. Common lengths usually range in 4-foot increments from 4 to 48 feet, with special orders reaching 60 to 80 feet in length depending on mill capabilities. The depth or thickness of the beams ranges from 5-1/2” like a dimensional 2×6 to 24”, with other common dimensional lumber thicknesses included. Common widths are 1-3/4” or single, 3-1/2” or double, 5-1/4” or triple, and 7” for quadruple. The span of laminated beams depends upon their width, depth, and potential loads. Additionally, the use of waterproof adhesives makes the beams acceptable for both interior and exterior applications. They are engineered to support greater loads over longer distances than other wooden beams. As a result, they are more than twice as strong as regular lumber of similar size, more uniform in dimensions, straighter, and resistant to twisting, bowing, and shrinking. LVL beams are made of laminated veneer lumber similar to plywood, except the grain of all layers is oriented longitudinally to mimic solid wood. How Far Can an LVL Beam Span Without Support?
