What size lvl to span 20 feet | what size lvl beam for a 20 foot span | what size lvl beam do i need to span 20 feet | laminated veneer lumber (lvl).
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. 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. 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 available in a wide range of lengths, widths and thicknesses.
The American wood Council National design specification for wood, lvl is type of structural composite lumber comparable to glued laminated timber (glulam). 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.
LVL is a straight, enough strong wood that fights warping and shrinking, providing great stability for your projects. Use an LVL beam to eliminate twisting and splitting for quiet floors. Because of the wood’s dimensional stability, inspection times are often reduced, too. LVL has a “maximum allowable bending stress” of 2,800 or 3,000 psi. 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 sizes (thickness, length & depth)
LVL sizes:- LVL sizes may vary according to manufacturer but lvl standard thickness are 1 3/4 inches to 3 1/2 inches. LVL length are generally available in 24, 28, 32, 36, 40 and 44 feet with special order upto 60 Feet. LVL beam depth are typically 5 1/2 inches to 24″, it comes in 7 1/4 inches , 9 1/4 inches , 9 1/2 inches, 11 1/4 inches, 11 7/8 inches, 14 inches, 16 inches, 18 inches, 18 3/4 inches, 20 inches and 23 7/8 inches.
LVL thickness:- LVL beam standard thickness are ranging from 1 3/4 inches to 7 inches. It comes in 1ply of thickness 1-3/4″, 2ply of 3-1/2″ thick, 3ply of 5-1/4″ thick and 4ply of 7″ thick.
LVL length:- LVL length are generally available in 24, 28, 32, 36, 40 and 44 feet with special order upto 60 Feet. It can be customised according to your requirement. More than 60 Feet there is difficulty in transportation and handling.
LVL beam depth:- LVL beam depth are typically 5 1/2 inches (140mm), 7 1/4 inches (184mm), 9 1/4 inches (235mm), 9 1/2 inches (241mm), 11 1/4 inches (286mm), 11 7/8 inches (302mm), 14 inches (356mm), 16 inches (406mm), 18 inches (457mm), 18 3/4 inches (476mm), 20 inches (508mm) and 23 7/8 inches (606mm).
In this article you know about what size lvl to span 20 feet, what size lvl beam for a 20 foot span, what size lvl beam do i need to span 20 foot and what is laminated veneer lumber (lvl) that will help you in better understanding and to figure out or estimate of lvl beam size and their depth.
What size lvl beam do i need to span 20 feet
Width of lvl beam:- design a beam width based on the fact that the typical width of an LVL beam is 1 3/4 inches. The width can be increased by laminating in multiples of 1 3/4 inches or 40mm. Beam width should be 1/4 to 1/3 beam depth.
Depth of lvl beam:- LVL beam depth are typically 5 1/2 inches (140mm), 7 1/4 inches (184mm), 9 1/4 inches (235mm), 9 1/2 inches (241mm), 11 1/4 inches (286mm), 11 7/8 inches (302mm), 14 inches (356mm), 16 inches (406mm), 18 inches (457mm), 18 3/4 inches (476mm), 20 inches (508mm) and 23 7/8 inches (606mm).
Design a beam depth based on the rule of thumb for estimating the depth of manufactured beams which is to divide the span by 20. Beam 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.

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 10 to 12 inches deep and 3-1/2 inches or 2ply wide, thus you need something like a 10-12″ GLULAM or LVL to span upto 20 feet and can use simple 2×14 dimensional lumber at 16″ apart from centre as floor joists used for residential building or projects.
What size lvl to span 20 feet:- a 3-1/2 × 11 1/4 or 4 1/2 × 9 1/2 standard size of LVL or 2×14 dimensional lumber at 16″ apart from centre can span upto 20 feet on normal weight condition which providing great stability for your projects.
20 ft lvl beam price:– on average, cost/ price of LVL is around $3 to $12 per linear foot. So, for 20 ft lvl beam price = 20×3 = $60 or 20×12 = $240, thus, price/ cost of 20 ft lVL beam or Laminated veneer lumber or Engineered beam would be $60 to $240 for materials or between $50 to $200 per foot for installation.
