Wesbeam is Australia’s only LVL manufacturer and distributor with a world class factory in Perth. Laminated veneer lumber - LVL - is an engineered wood product that’s lighter, stronger and straighter than traditional sawn timber. e-joist combines the latest engineered wood technology with LVL to create a floor joist that's lightweight, straight and strong. Manufactured from LVL and oriented strand board (OSB), e-joist has the same strength as a solid LVL beam of the same size but uses much less wood, making it lighter and easier to handle.
