More than 60 Feet there is difficulty in transportation and handling. It can be customised according to your requirement. LVL length are generally available in 24, 28, 32, 36, 40 and 44 feet with special order upto 60 Feet. It is available in thickness from 19mm (3/4 inches) to 178mm (7 inches). Lvl sizes may vary according to manufacturer but lvl standard thickness are 1 3/4 inches to 3 1/2 inches. 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. Providing the superior performance and durability of engineered wood, Murphy Company LVL is perfectly suit- ed to spans bearing heavy loads and multi-span. 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. So if you load a beam up to it's maximun design value that doesn't mean it's on the verge of breaking.The American wood Council National design specification for wood, lvl is type of structural composite lumber comparable to glued laminated timber (glulam). In all cases, the higher the number the better.Safety factors are already built into the design values. But they don't come into play much in residential LVL design. The value for modulus of elacticity is generally what they advertise, which makes no sense to me.Then there are other values, like tension, compression PARALLEL to the grain, comperssion PERPENDICULAR to the grain, and shear. Multiple spans are based on the longest span. They're loosely related, but not the same. Multiple span lengths shown require adequate lateral bracing of bottom edge of LVL. These 2 values are different - One is the strength, and on is for the elasticity. Works with evenly distributed loads only. Double check yourself with these span charts. 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. Covers any span and every load with pin point accuracy. 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. That tells how much bending stress a beam can handle before it breaks. Calculate the size needed for a beam, girder, or header made from No. There's also a vale called "Fb" - Some people call it "flexural stress", others call it "Extreme fiber bending". a double 16 lvl is made by laminating of two 1 3/4 inches or 40mm thick and 16 deep LVL. That tells how much a beam will deflect when a given amount of weight is put on it. Here are some examples:The number you mentioned, like "1.9" is the "modulus of elasticity". How much time have ya got ? Having trouble sleeping? Read this post just before going to bed for best results.(-:There are several different values assigned to lumber and beams.
