So, the cost of 28 ft lVL beam or Laminated veneer lumber or Engineered beam would be range between $84 to $336 for materials or between $50 to $200 per foot for installation. The price of LVL (Laminated veneer lumber) is around $3 to $12 per linear foot. So you would need something like a 5 1/4″× 16 LVL to span upto 28 feet used for residential building on normal weight condition. Typically for a 28 foot span, the size of LVL (Laminated veneer lumber) need to be 16 inches deep and 5 1/4 inches wide. So, you would need something like 5 1/2″ × 16″ size of LVL beam for 28 foot span. If beam spanning is 28 feet in length, then their depth = (28 × 12) ÷ 20 = approx 16 inches and width is 16/3 = approx 5″. What size lvl beam do i need to span 28 feetĪs per LVL span rule of thumb the depth of the LVL beam says 1/20th of span in inches and their width is 1/3 to 1/4 of the depth. hySPAN ® laminated veneer lumber (LVL) is easy to work with using traditional building tools and is clearly branded for easy identification and your guarantee of quality. Click here for 2012 IRC span charts and building codes. They have limits on how far they can span and rules on how they must be spaced and fastened. Typically they stretch from a wall plate to the ridge. What size lvl beam do i need to span 28 feet Rafters are the sloping beams that support the weight of a roof.LVL offer several advantages over technical milled lumber, it is made in factory under control specification and it is more stronger straighter and more uniform in size. LVL has a “maximum allowable bending stress” of 2,800 or 3,000 psi. Because of the wood’s dimensional stability, inspection times are often reduced, too. Use an LVL beam to eliminate twisting and splitting for quiet floors. LVL is a straight, enough strong wood that fights warping and shrinking, providing great stability for your projects. For beams continuous over two unequal spans, the design span and the 'Resultant Span Description' depend upon the per-centage difference between the two spans as shown below: Note, for continuous spans, the Design Span is taken as the dis-tance between the centre of the supports, as shown in Design Span on page of the Design Guide. 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. The American wood Council National design specification for wood, lvl is type of structural composite lumber comparable to glued laminated timber (glulam). It is available in a wide range of lengths, widths and thicknesses. It is typically used for boards of all kinds, for headers, beam rim boards, skateboards, as well as beams, trusses, edge forming materials and more. It is a high-strength structural engineered wood product of recent innovation and one of the most widely used kinds of lumber in construction projects in. Laminated veneer lumber or LVL is much look like plywood, generally made of thin sheets of wood which are sandwiched and bound with super stronger glue.
