Overview

Timber joists are a versatile and sustainable choice for construction projects across Australia. LVL (Laminated Veneer Lumber) is an engineered wood product made from thin layers of wood veneers glued together under high pressure and heat. Our engineered joists have increased strength with the versatility of typical lumber.

e-joist combines the latest engineered wood technology with LVL to create a floor joist that's lightweight, straight and strong and available in lengths up 13.2m.

Manufactured from LVL and oriented strand board (OSB), e-joist has a similar strength as a solid LVL beam of the same size but uses much less wood, making it lighter and easier to handle. 

Service holes can easily be cut through the 9.5mm OSB web with the assistance of the e-joist design guide. 

The Wesbeam Design Centre offers a floor design and quote service for Wesbeam customers. We have the only 3D timber software with whole-of-house load tracing capability.

The e-joist is a lightweight, straight, and strong floor joist that incorporates advanced engineered wood technology and LVL. It is available in lengths up to 13.2m.

  3. Do not stack e-joists on the flat
  4. Cover e-joist to keep dry while allowing for ventilation
  5. Avoid placing e-joist over areas susceptible to ponding..
