![]() ![]() Other manufacturers also make LVL engineered products, and all use similar processes for making engineered lumber. Weyerhauser referred to the product as “Microlam” for two years until then changed it to “Microllam.” Many still refer to Microlam when speaking of Microllam as they are frequently interchanged to identify all types of laminated veneer lumber. Microlam and Microllam refer to the same LVL product. Microlam is a common misspelling of Microllam, a Weyerhauser brand of engineered wood products. They are cut to size, wrapped, and prepped for storage or transportation. The process to get to a finished LVL beam starts with debarking the log, then rotary peeling the veneer to send the sheets to the jet tube dryers to reduce the moisture content to 8-10%.Īfter drying, the manufacturer grades the veneer sheets, gets a resin application, and compresses the sheets until dry. The most common wood used in LVL beams is Douglas fir. During World War II, plywood became an essential war material. There is recorded use by the Chinese, English, French, and Russians well before the 20th century, and it received its first patent in 1856. An LVL engineering process uses multiple layers of thin wood assembled with adhesives.Įngineered lumber was first seen in use as early as ancient Egypt. LVL is typically made in a factory, straighter, more uniform, and stronger than traditional milled lumber. The difference is that plywood changes the grain’s direction with each layer, and LVL keeps the grain direction the same. LVL stands for Laminated Veneer Lumber and is similar to plywood in appearance. 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. 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). ![]()
