Maximum spans are inside to inside of bearings Lumber Span Tables for Spruce-Pine-Fir South (SPFs)**Typically a 10″ LVL (laminated veneer lumber) double ply (3-1/2 inch) beam can be span to a distance of 16 feet when used in residential homes or projects. How far can a double 12″ lvl span. A 12″ double LVL is made by laminating two LVLs 1 3/4″ or 40mm thick and 12“ deep.There's not quite enough information here to give a definitive answer, but for decks, a rule of thumb is when supporting joists that span 12 feet, a double ply beam can span in feet a value equal to its depth in inches. Thus, a double 2x12 beam could span 12 feet - with 20' beams, posts at 10' might look the best.LP SolidStart LVL beams are exceptionally strong, solid and straight, making them excellent for most primary load-carrying beam applications.

(the tables permit a bearing length of up to 3.5 inches, but since 1.5 is probably the worst case that you’ll encounter for joist or rafter bearing, it’s a safe value.) According to the 2012 IRC codes any beam, joist, or header shall never have a bearing of less than 1 1/2″. Anything 5′ and above we always at least double cripple. On longer spans the beam may require much more bearing space as indicated by this table. Fastening. Beams of more than one ply must be fastened together with either nails or bolts. 2) Alternative Lumber. Next, laminated veneer lumber (LVL) and parallel strand lumber (PSL) are engineered wood products that you can use for pole barn headers. LVL is produced by bonding thin wood veneers together in a large billet. As a result, the veneer grains run parallel to the long direction.02-Apr-2023 ...
