Overview

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.
