It runs between full length supports and along its length and carry the load of shorter studs, joists or rafter that terminate at the opening. It is often made of two joists, rafter or studs. Typically header is provided at least twice size then any other surrounding members such as rafter purlin and stud. LVL header provide structural support in wood frame construction. LVL header definition & functionĪ header is a horizontal beam generally made of timber or Laminated veneer lumber or LVL that provided along the opening in full length for doorway, window, skylight or stairway. More than 60 Feet there is difficulty in transportation and handling. It can be customised according to your requirement. LVL length are generally comes in 24, 28, 32, 36, 40 and 44 feet with special order upto 60 Feet or 4′ increments. It comes in 1 ply of 1-3/4″ width, 2 ply of 3-1/2″ width, 3 ply of 5-1/4″ width and 4 ply of 7″ width. LVL header standard width are range between 1 3/4 inches to 7 inches.

Depth of the LVL headerĭepth of the LVL header are typically range between 5 1/2 inches to 23 7/8 inches. 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 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). The most common thickness of Laminated veneer lumber or LVL of 1 ply is 45 mm or 1-3/4 inches, from which wider header can be easily constructed by fastening multiple LVL plies together on site. Laminated veneer lumber or LVL are available in 1 ply of thickness 1 -3/4″ (1.75″), 2 ply LVL of thickness 3 -1/2″ (3.5″), 3 ply LVL of thickness 5 -1/4″ (5.25″) and 4 ply LVL of thickness 7 inches wide. 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.
