Design Considerations
Gable Units Attached Between a Flat Unit & an Existing Structure
Gable Units which are attached between a Flat Unit and an existing house, shall only be considered attached if the Gable 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 length (L). The Flat Unit in this case can be considered attached. This style requires all coloumns to be embedded into footings.
Gable Units Attached to Flat Unit One or Both Sides
Gable Units which are attached one or both sides to Flat Units, must be attached to an existing house for at least 75% of the gable opening length (O) to be considered attached. Flat Units must be deemed attached as detailed in the Flat Unit section below to allow the Gable Unit to be considered attached.
Gable Units are considered attached both sides if both Flat 1 and 2 comply with attachment rules for Flat Units as detailed below. Gable 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.
Design Options
When designing a Pergola, 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.

Gable Roof
Choosing a Design
The Stratco Gable is available as an attached unit on the house and can be combined with a flat roof design that makes the pitched roof a prominent feature of the arrangement. The Stratco Gable is available as a Multispan or Clearspan design. Match the Stratco Roof Deck with Stratco Rooflites to supply natural filtered light.
Multispan
A Stratco Multispan Gable features purlins that are placed over the rafters in the roof. This supports the cladding, which can be the smooth Stratco Roof Deck, light and airy polycarbonate, or classic corrugated steel. The gable roof can span up to 6.6 metres wide on a Multispan design.
Clearspan
The Stratco Clearspan Gable only uses the Stratco Roof Deck, which is a very strong material and does not need the extra purlins to support it. This leaves the roof area clean and uncluttered. The Clearspan Gable can span an impressive 7.5 metres wide.
Invest In Quality
Available in a wide range of high gloss colours to complement your home, the Stratco system utilises the unique Stratco Roof Deck, a steel roofing sheet with a smooth underside that has a 'ceiling-like' finish. It can span up to 4.5 metres, allowing the support beams to be placed well apart for a clean, uncluttered finish. The structure is formed with strong and elegant, chamfered and fluted beams and columns. Matching gutters tie the system together, while hidden fixing points and concealed brackets complete the smooth and refined appearance.
The durable Stratco Patio or Carport will be a lasting investment. It is protected by a fifteen year structural guarantee (conditions apply) and, when installed by an Authorised Stratco Dealer you are covered by a one year installation guarantee. The Stratco range has been engineered and tested to comply with all relevant New Zealand Standards. The major components are made from strong high tensile steel, while the fixings and brackets are galvanised for a long useable life.
