I-Joists

The JJI-joists are structurally engineered timber joists, combining high-grade softwood with an engineered composite panel.

Using advanced technology these components are combined to produce an innovative alternative to conventional construction timber.

JJI-joists offer many design and performance advantages over conventional sections, such as:

	Strong – superior strength to weight ratio enables longer spans
	Straight – straighter and with uniform dimensions
	Light – lighter and easy to handle with eased edges
	Long – length restricted only by transport method
	Stable – composition resists shrinking and warping
	Cost effective – saving on time, labour and material
	Convenient – easy to cut, drill and install
	Versatile – design flexibility in floor, wall and roof applications
	Environmentally friendly – use 40-60% less material and less site wastage
	Quality ensured – an engineered system that is factory produced
