![]() Overhang Span.Sometimes referred to as cantilever, overhang is the distance from the face of the support to the free end of the beam, measured along the beam as illustrated. Seeking guidance from a structural engineer is imperative to ascertain the precise size and specifications required to ensure safety and adherence to regulations. However if either of the above conditions are not met, use the single span tables for the purpose of obtaining the appropriate size. The dimensions of the beam will vary based on load considerations and the chosen material. Generally, you can find LVL beams in a 4-foot increments starting at 24 feet and going up to 44 feet long, with special customize size up to 60 feet. To cover a 30-foot span, one can utilize either a multiple-ply 2×12 or opt for engineered wooden beams like LVL. An LVL beam can span up to 60 feet due to its strength and is much stronger than traditional lumber. My plan was to nail and glue 2×12’s with 1/2 ply wood in the middle to make a 48ft ridge board this will be supported by 4×4’s and 2×6’s. These beams are often custom-manufactured to precisely meet the specific requirements of your project. I will be using 6×6 poles on 8ft centers with 2×6 framing in between, with 1/2 osb on the outside. As a general guideline, for a 30-foot span, it is typically recommended to use LVL beams with dimensions of 5-1/4″ × 13 1/2″ or 5-1/4″ × 16″. ![]() Fewer posts on upper-level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans.

The size of LVL beams required for a 30-foot span is contingent on several factors, including the anticipated load and compliance with local building codes. The span of a beam is dependent on a few variables: The grade and species of lumber, size of lumber and the load it carries. ![]() Steel beams reign supreme in this domain, offering unmatched load-bearing capacity and durability. Our next step is to check if this deflection is less than the allowable deflection for our given beam span. When spanning a 40-foot distance, the choice of I beam becomes crucial. ![]() They can easily be built-up on site to reduce heavy lifting. Selecting the Optimal I Beam for a 40-foot Span Material Selection: The calculator allows you to consider different LVL beam materials (e.g., LVL 1.9E, LVL 2.0E) and their respective strengths when determining the beam size. Microllam® LVL beams work well in applications all over the house. ![]()
