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. These calculation results are only to be used as a handy guide (not for construction) when designing your project joist spans. This can be a solid bottom edge bearing (like a wall) or face fixed metal hanger 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 Our VERSA-LAM LVL is manufactured in either Alexandria (Lena), Louisiana in Eastern United States, or in White City, Oregon for the Western United States. Joist Centres is 300mm then it 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. VERSA-LAM laminated veneer lumber (LVL) beams and headers eliminate twisting, shrinking and splitting, and deliver flatter, quieter floors and structures. Centres” is 600mm, the joist can be used at the lower nominated spacings ie 300mm, 400mm, 480mm, and 600mm centres. A 14, 16, and 18 deep will all span 30’, but 16 and 18 are typically doubled or tripled for greater loads. Centres are the maximum centres that this joist can be installed at. A 1-3/4 2.1E 2800 beam with 100 load duration that is 7-1/4 deep will span up to 16’, an 9-1/2 deep will span to 20’, and 11-7/8 deep to 26’. The Class 1 classification includes two sub-classifications: Class 1a and Class 1b ![]() In these situations, they must be separated by a wall that has fire-resisting and sound insulation properties.
