Light weight
Each joist is a fraction of the weight of solid timber of equal dimension and performance. This allows greater efficiency on the building site by employing the labour more effectively as well as reducing worker exhaustion.

Consistent dimensions
Constant flange widths and joist depths allow for greater accuracy when framing a suspended floor. SuperJoist Engineered Joists are manufactured to a tolerance of ± 1,0mm on the depth and ± 1,0mm on the flange width.

Straight
Bowed, twisted and badly machined joists are a thing of the past with SuperJoist Engineered Joists. Now there is no need to spend valuable site-time sawing and planeing to get the floor framing level and flat.

Comparable spans
SuperJoist Engineered Joists have spanning capabilities that are equal to solid timber of similar dimensions. See our load span table for more information.

Long lengths
SuperJoist Engineered Joists can be made in lengths of up to 10,1m for multiple spans. Single span lengths of 4,8m and 5,1m are stock items.

Resource friendly
SuperJoist Engineered Joists use up to 60% less solid local timber to achieve the same results as solid timber joists, more efficiently and cost effectively.

Preservative Treated
The flanges are Tanalith preservative treated to H2 for a long lifespan.  The OSB web is resistant to degradation and insect attack as each wafer is adhesive coated in the manufacturing process.

Economical
SuperJoist Engineered Joists are competitively priced – saving the contractor time and money.

Application
SuperJoist Engineered Joists are ideal for use in construction applications where the joists or rafters will not be exposed to the elements on a permanent basis.

Not suitable for deck joists or pergolas.
