2 It is manufactuered by laminating Maritime Pine veneer, using phenolic adhesive, in a continuous assembly in which the grain direction of all veneers runs longitudinally. It is pressed as a m nominal width continuous billet in various standard thicknesses, cut to standard widths and any specified length for use as structural beams and other framing of e-beam DataThe Tables and other technical data provided in this publication are only applicable to e-beam LVL manufactured by Wesbeam . This data should not be used for look-alike or substitute products. Use of the e-beam data for look-alike or substitute products can result in unsafe or unsatisfactory for DesignThe design criteria used to develop the span Tables contained in this brochure are based on the assumptions listed in 1999 Residential timber framed LoadsThe design loads used to determine member sizes listed in the span Tables are as per 1999 Residential timber framed construction.

3 The design loads include:- Dead loads Live loads Wind loads Snow loads Earthquake loads, and Load Combinations of the above loadsDesign load limitations for each of the above load or load combination cases are also as per 1999 Residential timber framed Capacity Factor ( )The capacity factor ( ) used to calculate the design capacity of a structural framing member listed in the span Tables is taken from table in 1997 where for all LVL structural elements used in residential houses = , Definitions & Notations Used in these TablesThe terminology, definitions and notations used in this brochure are similar to and consistent with those used and listed in AS1684 1999 Residential timber framed to loadengineered to lengthengineered to lastend of storyUsing Multiple Sections The use of multiple sections where called for in the span Tables is permitted using vertically nail laminated LVL.

4 Multiple LVL members are to be fixed in accordance with Cl of 2010. Characteristic Design ValuesThe characteristic Design Values for Wesbeam e-beam LVL are available on request from Wesbeam s Technical Department. This service is available for professional design spans listed in this brochure for e-beam LVL manufactured by Wesbeam apply only when the moisture content of the LVL is below 15% in service and are for on edge orientation of the LVL is the premier laminated veneer lumber (LVL) product available in Australia. LVL has many advantages over traditional building products, including its uniformity of engineering properties, it s high strength to weight ratio and its availability in longer lengths.

5 Available in a range of thicknesses including 35mm, 45mm, 63mm and 75mm with depths from 90mm to 450mm, e-beam is manufactured from plantation timbers, making it an environmentally sustainable resource. 45e-BEAMS ectionD X B(mm)Roof Masskg/m Single SpanContinuous SpanMaximum Rafter Spacing (mm)45060090012004506009001200 Maximum Rafter span and Overhang O/H (m)SPANO/HSPANO/HSPANO/HSPANO/HSPANO/HSP ANO/HSPANO/HSPANO/H90 x .. x . x .. x .. x .. x .. x .. x ..
