Enhance your lifestyle with a Stratco Outback Gable veranda, patio or carport

The Stratco Outback Gable is available as a freestanding unit or attached to your home. Combined with flat roof or pergola sections, the prominent pitched roof becomes the main feature of the design.

The gable is available in our Multispan or Clearspan design. Match the Outback Deck with Outback Rooflites to supply natural filtered light.

Multispan Gable

The Outback Multispan Gable offers a range of roof cladding materials. It features purlins that are placed over the rafters in the roof. This supports the cladding, which can be the smooth Outback Deck, light and airy polycarbonate, or classic corrugated steel.

The gable can span up to 6.6 metres wide when attached at both ends, or 3 metres wide when attached at one end.

Clearspan Gable

The Outback Clearspan Gable uses only the Outback Deck, a very strong material that does not need extra purlins to support it. This leaves the roof area clean and uncluttered.

The Clearspan Gable can span an impressive 7.5 metres wide with a 22 degree pitch.

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 4.8mm sealed aluminium rivets per pan (or 150mm centres if sheets are parallel) to be used at the back channel. All screws are to have neoprene washers.

Design Considerations

Gable/Curved Units Attached Between a Flat Unit & an Existing Structure

Gable/Curved Units which are attached between a Flat Unit (excluding pergolas) and an existing house, shall only be considered attached if the Gable/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 gable/curved length (L). The Flat Unit in this case can be considered attached. This style requires all columns to be embedded into footings.

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

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

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

Flat Units

A Verandah, Patio, Carport or Pergola is deemed to be freestanding unless it is attached to an existing house (C) for at least 75% of the length of its shortest side (A), and its longest side (B) does not exceed twice the length of its shortest side.

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 appearance and drainage requirements. The following shows some of the normal options used.
