45mm LVL E13 H2 Beam
45mm LVL E13 H2 Beam Sydney
When the framing schedule calls for a slim, high-performance structural member, the 45mm LVL E13 H2 beam is the specification. Engineered to an E13 modulus of elasticity rating of 13,000 MPa, it delivers the stiffness and load-bearing consistency that sawn timber cannot match across a full residential frame. H2 preservative treatment protects against termites and borers in above-ground interior applications, making it the correct choice for floor joists, lintels, bearers, and roof members where performance needs to be predictable from the first fix to the last.
Built for Residential Framing
At 45mm wide, this beam is the standard single-ply section for residential floor joists and wall lintels. Where a heavier section is needed, multiple 45mm plies can be built up on site using structural fixings, giving the framing crew flexibility without changing suppliers. LVL eliminates the knots, shakes, and moisture variability that affect sawn timber, so every member performs as engineered regardless of where it sits in the frame.
For wider single-ply applications, our 63mm LVL E13 H2 beam provides a greater bearing face for portal frames, heavier lintels, and longer spans. Both sections are H2 treated and available in standard residential lengths.
LVL floor joists need to be properly connected at every bearing point, and framing connectors rated for engineered timber are stocked alongside our LVL range for exactly this reason. Once the frame is up, bracing and sub-floor sheet products for wall and floor applications are available in the same order.

Frequently Asked Questions
What does E13 mean on an LVL beam?
E13 refers to the modulus of elasticity rating of the beam, 13,000 MPa. It is a measure of stiffness. A higher E rating means less deflection under load, which is why E13 is specified for structural framing applications like floor joists and lintels.
What does H2 treatment mean for LVL?
H2 is a preservative treatment that protects the timber against termites and borers. H2-treated LVL is suitable for above-ground interior applications in residential construction. It is not rated for ground contact or high-moisture exposure.
What is the difference between 45mm and 63mm LVL E13 H2?
The 45mm section is suited to single-ply floor joists, lintels, and roof members where a slimmer profile is required. The 63mm section provides a wider bearing face for heavier loads or longer spans.
All variations of LVL are subject to strict quality control and are manufactured and tested in accordance with the AS/NZS 4357:2005 Structural Laminated Veneer Lumber standards, with Design Characteristic Values determined to be in adherence to AS/NZS 4063.2:2010 Section 4.
Can 45mm LVL beams be used for floor joists?
Yes. The 45mm E13 H2 LVL is a standard floor joist section in residential construction. Confirm the span and load requirements against the relevant span tables or with your engineer before specifying.
Do you need engineer approval to use LVL in a residential frame?
LVL is a structural product and its use in residential framing should be specified by a qualified engineer or building designer. Span tables are available from the manufacturer and your engineer will confirm the correct section size, spacing, and fixing schedule for your application.
Can 45mm LVL be built up to create a multi-ply beam?
Yes. Multiple 45mm plies can be built up on site using structural fixings to create a heavier composite beam where a single-ply section is insufficient. Consult your engineer for the appropriate ply count and fixing schedule for your application.
