LAMINATED BEAMS
XLT Beam is a laminated timber beam engineered for load-bearing strength. Offered in a wide range of sizes and lengths, XLT Beam delivers consistent performance with proven design properties, tested in accordance with AS/NZS 4063 and certified under CodeMark. Easily specified using CodeMark-certified span tables, XLT Beam meets the requirements of the NCC and NZBC for both residential and commercial applications.
Made from sustainably grown plantation pine, which locks away carbon as it grows. Trees are replanted for a continuous cycle of carbon storage, and beams are bonded with formaldehyde-free adhesives.
Engineered for long spans and superior load capacity, removing the need for steel beams, streamlining structural design and enhancing efficiency.
XLT Beam is available as H3 (AUS) or H3.2 (NZ) treated. With CodeMark-certification, you’re assured that it provides leading protection against termites, borers, fungal decay, and rot.
Our treatment has no Volatile Organic Compound (VOC) emissions. It’s a powerful next-generation water-based treatment, free from chemical solvents.
XLT Beam is available in a variety of sizes, including deeper sections for specialised applications.
Compatible with traditional timber framing and available in a range of sizes to match framing widths, XLT Beams make installation simple—no nail-laminating or packers required.
Perfectly suited for rafters, lintels, joists and bearers, XLT Beams are made from solid timber that holds nails—offering a robust alternative to LVL, I-Joists and steel.
Certified to meet the Australian Building Code.
Sourced from PEFC certified sustainably managed Australian plantations.
Safe to handle and LBC ‘Red List’ free.
