LVL is available through our network of UK distributors, for contact details of your nearest distributor visit our Distributor Map.Īlternatively, contact our Timber Systems Division team directly, individual contact details can be found in our Contacts section. LVL has excellent construction properties and is: For further details see the LVL technical manual below. Our close relationship with Stora Enso provides James Jones & Sons Ltd with the confidence to offer a full range of LVL grades and billet sizes. JJLVL-Beam is a natural choice for highly loaded beams, whereas JJSLVL-Rim is the most cost-effective solution for rim material in timber frame structures. The LVL that James Jones supplies to the market is available in two grades, JJLVL-Beam and JJLVL-Rim, and three standard thicknesses - 30, 45 and 75mm, with depths to match the full JJI-Joist range. Our next step is to check if this deflection is less than the allowable deflection for our given beam span. As a material, LVL is exceptionally strong with excellent load bearing capacity, homogeneous quality and good workability. These resources are referenced in the International. Final design confirmation and for further design options, including continuous spans or non-uniformly loaded joists, please refer to the Dindas Design Guide or reach out to us at any of our state locations or request information through .LVL is an advanced wood product suitable for a wide range of structural applications, available in beam depths which complement our JJI-Joist range. Resources provide a simplified system to determine allowable joist and rafter spans in one- and two-family dwellings, and the companion supplements for tabulating allowable bending and modulus of elasticity design values for visually graded and mechanically graded dimension lumber. These calculation results are only to be used as a handy guide (not for construction) when designing your project joist spans. The lengths typically run from 4 to 48, with. Laminated veneer timber is commonly available in widths or thicknesses of 1-3/4, 3-1/2, 5-1/4, and 7, as well as depths ranging from 5-1/2 to 24, including standard and nonstandard depths. This can be a solid bottom edge bearing (like a wall) or face fixed metal hanger. LVL Beam and Span Support: The length of an LVL beam is governed by its width and depth. bearing conditions (35mm) or greater have been included in the design. * Joists with a Max.Centre spacing of 600mm or less = 22mm min * Joists with a Max.Centre spacing of 450mm or less = 19mm min For simple construction, such as domestic construction, this can be determined from span table supplements in AS1684.2 and AS1684.3. Joist Centres are 300mm, and they can only be used at any joist centres equal to or less than 300mm centres.įlooring thickness must be checked before installation to ensure it can span the intended Max. Span tables allow users to choose an appropriate size and stress grade to achieve spanning needs. Centres” is 600mm, the joist can be used at the lower nominated spacings ie 300mm, 400mm, 480mm, and 600mm centres. View Size Selection Tables View Allowable Load. Centres are the maximum centres that this joist can be installed at. Simplified span tables for Southern Pine lumber and glued laminated timber (glulam) headers, beams and girders. The Class 1 classification includes two sub-classifications: Class 1a and Class 1b In these situations, they must be separated by a wall with fire-resisting and sound insulation properties. Example Calculation: Let's assume you have an LVL beam with a width of 5 inches, a depth of 12 inches, and it needs to support a uniform load of 1,000 pounds per square foot. They can also be horizontally attached to other Class 1 buildings, such as terrace houses, rowhouses, or townhouses. Review Maximum Safe Span: The calculated maximum safe span for the LVL beam will be displayed on the page. Typically they are standalone single dwellings of a domestic or residential nature.
