Dimensions
50 x 30 x 3,000 mm (also printed 30 x 50 x 3,000 mm)
Material grade
Aluminium EN AW-6005 T6
Quantity rule
One joist every 350 mm or less; 250 mm or less in high-load or tropical conditions
The extruded aluminium joist that carries every Tarimatec deck. Aluminium is used rather than timber because it does not rot, twist or absorb water, and it holds the hidden clip at a consistent height across the field.
Joist spacing is the single most important installation variable: 350 mm centres or less for standard residential and commercial decks.
