These are known as Cross-Banded LVLs and may need to be specially ordered, as it is not a commonly stocked item. Note: Some LVL members can be made with a few laminations laid up at right angles to enhance the shear strength of the member. LVL provides a cost-effective and sustainable building material, delivering high structural reliability and strength. A high performance more sustainable alternative to lumber, Murphys Laminated Veneer Lumber (LVL) beams, headers and columns are used in structural. The ability to cut different shapes from the LVL sheets allows for structural innovation using angular and curved shapes.
Section sizes are then cut from 1200 m wide sheets or "billets". LVL can also support heavier loads and span longer distances than normal timber.
The added durability of being an engineered wood product means LVL is less prone to shrinking or warping. In this episode of WoodSolutions InFocus Laurence visits a factory which produces Laminated Veneer Lumber to see how it is made. This gives orthotropic properties (different mechanical properties against different axes) in a similar way to the properties of sawn timber, rather than the isotropic properties (the same mechanical properties in each direction) in the plane of plywood. This makes LVL stronger, straighter and more uniform than solid timber and overcomes some of timber's natural limitations such as strength-reducing knots. A high performance more sustainable alternative to lumber, Laminated veneer lumber is an engineered wood product that uses multiple layers of thin wood. Prior to lamination, the veneers are dried and the grains of each veneer are oriented in the same direction. LVL can be used wherever sawn timber is used however one of the main advantages is that it can be manufactured to almost any length, restricted only by transportation to site. LVLs range in sizes from 35mm to 63mm (75mm) in thickness and a depth from 90mm to 600mm with strength ratings in comparison to. LVL was developed in the 1970s and is today used for permanent structural applications including beams, lintels, purlins, truss chords and formwork. It is comparable in strength to solid timber, concrete and steel and is manufactured by bonding together rotary peeled or sliced thin wood veneers under heat and pressure. Laminated Veneer Lumber (LVL) is a high-strength engineered wood product used primarily for structural applications.

An LVL panel is calibrated on two sides, which reduces the thickness by 3 mm in total (1.5 mm per side). Laminated Veneer Lumber (LVL) is a high-strength engineered wood product used primarily for structural applications. ** Calibration increases the panel's thickness tolerances. Sanding reduces panel thickness by approx. * LVL panels can be sanded on one or two sides. Exceptional size accuracy minimises the need for remedial work when the prefabricated elements are delivered on site, which speeds up the building process and reduces construction costs. LVL S/X and LVL G grades are manufactured in a modern, factory controlled environment and cut to size with highly accurate CNC processing.
