Spanning Capabilities & Technical Information

  • Domestic Installation: Spans up to 1900mm

  • Commercial Installation: Spans up to 1350mm

Domestic Application

The Standard Ali-Deck board is suitable for everyday use. It will span between the Ali-Deck Supa Joist up to a maximum span of 1900 mm (based 1/350 deflection criteria and a loading of 1.5 kN/m2). If a firm specification is required you can span a maximum of 1700 mm between the Ali-Deck Supa Joist (based 1/480 deflection criteria and a loading of 1.5 kN/m2).

The Ali-Deck Supa Joist Spans using the 8.0 mm L brackets: The Ali-Deck Supa Joist is capable of spanning a maximum span of 3000mm between upright ground supports (based 1/350 deflection criteria and a loading of 1.5 kN/m2).

If a firm specification is required the Ali-Deck Supa Joist will span 2700 (based 1/480 deflection criteria and a loading of 1.5 kN/m2).

The Ali-Deck Supa Joist Spans using the flat T and L brackets (both sides): The Ali-Deck Supa Joist is capable of spanning a maximum span of 2800mm between upright ground supports (based 1/350 deflection criteria and a loading of 1.5 kN/m2).

If a firm specification is required the Ali-Deck Supa Joist will span 2500 (based 1/480 deflection criteria and a loading of 1.5 kN/m2).

Commercial Application

Ali-Deck boards are suitable for commercial use. It will span between the Ali-Deck Supa Joist up to a maximum allowable span of 1350 mm (based 1/350 deflection criteria and a loading of 5.0 kN/m2).

If a firm specification is required you can span a maximum of 1200mm between the Ali-Deck Supa Joist (based 1/480 deflection criteria and a loading of 5.0 kN/m2).

The Ali-Deck Supa Joist Spans using the 8.0 mm L brackets: The Ali-Deck Supa Joist is capable of spanning a maximum span of 2200mm between upright ground supports (based 1/350 deflection criteria and a loading of 5.0 kN/m2).

If a firm specification is required the Ali-Deck Supa Joist will span 2000 (based 1/480 deflection criteria and a loading of 5.0 kN/m2).
