Summary
I-joists are engineered timber structural components for use in floors, walls, and roofs. They have a high ratio of strength and stiffness to weight. They are easy to install and economic to use, making them popular for long spans and multi-storey structures.
Timber I-joists are used as floor and roof joists, wall studs, and roof rafters in both residential and commercial construction.
