Fixing Details

For Non-Cyclonic Areas

Two 12 x 20mm self drilling screws per pan at each support and two 3.2mm sealed aluminium rivets per pan at the back channel. If decking runs parallel to the back channel, secure to channel with rivets at maximum 200mm centres. All screws are to have neoprene washers.

For Cyclonic Areas

Three 12 x 20mm self drilling screws per pan at each support. For deck spans less than 3600mm, two self drilling screws per pan are to be used on fascia beam. Three 3.2mm sealed aluminuim rivets per pan (or 150mm centres if sheets are parrallel) to be used at the back channel. All screws are to have neoprene washers.

Design Considerations

Curved Units Attached Between a Flat/Sunroof Unit and an Existing Structure

Curved Units which are attached between a Flat/Sunroof Unit (excluding pergolas) and an existing house, shall only be considered attached if the Curved Unit is attached to the existing house (C) for its full length (L) and the longest side of the combined unit (B) does not exceed twice the curved length (L). The Flat/Sunroof Unit in this case can be considered attached. This style requires all coloumns to be embedded into footings.

Curved Units Attached to Flat/sunroof Unit One or Both Sides

Curved Units which are attached one or both sides to Flat/Sunroof Units, (excluding pergolas) must be attached to an existing house for at least 75% of the curved opening length (O) to be considered attached. Flat/Sunroof Unit/s must be deemed attached as detailed in the Flat/Sunroof Unit section below to allow the Curved Unit to be considered attached.

Curved Units are considered attached both sides if both Flat/Sunroof 1 and 2 comply with attachment rules for Flat/Sunroof Units as detailed below. Curved Units are considered attached one side if only one Flat/Sunroof Unit exists and it complies with the attachment rules for Flat/Sunroof Units as detailed below.

Design Options

When designing an Outback, consideration should be given to both Roof sheet direction, and the orientation of any openings and overhangs involved. These are often determined by appearence and drainage requirements. The following charts show some of the normal options used, but contact Stratco if assistance is required.

Outback Curved Verandah
Attached to Wall or Fascia One Side Only	Attached to Flat/Sunroof Unit One Side and Wall or Fascia One End
Attached Both Sides to Flat/Sunroof Unit & Wall or Fascia Opposite Side	Attached to Flat/Sunroof Unit Both Sides & Wall or Fascia One End
Rear Attached to Wall or Fascia (Full Length)
Note: When attaching Curved Verandahs to Sunroof Units, please refer to “The Rules of Attachment to Standard Outback Systems” in the Outback Sunroof Span Tables Book.
