  • Available in Queensland only
  • May be used on roof pitches from as low as 2 degrees (1 in 30)

Spanning Table

The maximum recommended support spacings are based on testing in accordance with AS 1562.1-1992. Design and installation of sheet roof and wall cladding, and AS 4040.1-1992. Resistance to concentrated loads.**

The pressure considered is based on a typical awning Cpn=-0.8 and Kl=1.5 adjacent to an enclosed structure.

The tables are based on FLATDEK® II fixed to supports of 1.0mm BMT minimum. For FLATDEK® II awnings applications, the awning span is often governed by the capacity of the receiver channel and its connections. This must be considered in the design of any awning system.

Depending on support spacings used, FLATDEK® II can be installed as either a:

  • Light foot traffic roof (incidental maintenance foot traffic acceptable); or
  • No foot traffic roof (will not support the weight of a person walking on it), this considers resistance to wind pressure only.
