LVL beam width should be 1/4 to 1/3 beam depth.įor example what size lvl beam for a 20 foot span, as per general thumb rule, for a 20 foot span, size of LVL beam or GLULAM should be (20×12)÷20 = 12 inches deep and width of LVL beam = 12÷ 4 = 3″, which is nearly equal as 3-1/2 inches or 2ply wide, thus you need something like a 12″ thick or 3-1/2″× 11-7/8″ size of LVL beam to span up to 20 feet.Īn LVL beam can span up to 60 feet due to its strength and is much stronger than traditional lumber. Because of the wood’s dimensional stability, inspection times are often reduced, too.īeam depths are typically 5-1/2 inches, 7-1/4 inches, 9-1/4 inches, 11-1/4 inches, 11-7/8 inches, 14 inches, 16 inches, 18 inches and 20 inches. Use an LVL beam to eliminate twisting and splitting for quiet floors. It is a straight, enough strong wood that fights warping and shrinking, providing great stability for your projects. LVL beam is generally made of thin sheets of wood which are sandwiched and bound with super stronger glue. It helps in better understanding about span and depth of LVL beam. This article describe about LVL beam span calculator and how to determine size of beam do you need. It is typically used for headers, beams, rim board, and edge-forming material. Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. LVL is product of recent innovation they are result of new technology and economic pressure to make use of new wood species and smaller trees that cannot be used to make solid Lumber. How far can a double 2×12 beam spanĪs per general rules and guidelines, a double 2×12 deck beam (#2 grade southern pine) can span upto 12 feet when total load of 50 psf (40 psf live load + 10 psf dead load) with deflection limit L/360.Īs a general guide, a 2×12 double deck beam (#2 grade Southern Pine) can span up to 12 feet without support with a total load of 50 psf (40 psf live load + 10 psf dead load) and deflection limit of L/360.The American wood Council National design specification for wood, lvl is type of structural composite lumber comparable to glued laminated timber (Glulam). How far can a double 2×10 beam spanĪs per general rules and guidelines, #2 grade southern pine of a double 2×10 deck beam can span upto 10 feet when total load of 50 psf (40 psf live load + 10 psf dead load) with deflection limit L/360.Īs a general guide, a 2×10 double deck beam (#2 grade Southern Pine) can span up to 10 feet without support with a total load of 50 psf (40 psf live load + 10 psf dead load) and deflection limit of L/360. Typically a #2-Southern pine of a double 2×8 deck beam can span upto 8 feet when total load of 50 psf (40 psf live load + 10 psf dead load) with deflection limit L/360. Joists are technically beams that typically spans relatively short distances compared to beams and are made of wood, steel, or engineered wood or lumber.Īs a general guide, a 2×6 double deck beam (#2 grade Southern Pine) can span up to 6 feet without support with a total load of 50 psf (40 psf live load + 10 psf dead load) and deflection limit of L/360. It is like the skeleton/ framing of a building that supports the load which the floor is built to bear. Their function is similar as beams, except floor joists are supported by wall, foundations, or beams framing.īeam carries the load and transfer the dead load of the subfloor and floor finishes and live load of people, furniture and furnishings to walls, headers, or foundation walls. Floor joists are typically a horizontal structural member that runs across an open space of building on supporting wall or studs. Grade 1 lumber have higher strength than other grade Lumber due to fewer knots.Ī double 2×6 are made when two 2×6 beam nailed together, a double 2×8 are made when two 2×8 beam nailed together, a double 2×10 are made when two 2×10 beam nailed together and a double 2×12 are made when two 2×12 beam nailed together.ĭeck beam provides structural support to floor joists can be define as several small beams. Southern yellow pine is strongest species of wood that can span more distance compared to other species of wood. There are different depth of deck beam made of timber are used in floor construction such as 2×6, 2×8, 2×10 and 2×12 etc made of different species of wood (southern yellow pine & Douglas fir) and different grade such as grade – 1, grade – 2, grade – 3.
