Testing
Stramit Sunset® Patio Panel gives excellent durability in almost all locations. However, it is important to choose the correct coating for each application environment. Durability recommendations do vary based on the application of the product in roofing or walling installations.
All building products need to be checked for compatibility with adjacent materials. These checks need to be for both direct contact between materials, and where water runs from one material to another.
The following guidelines generally avoid material incompatibility:
- For zinc-aluminium alloy coated steel, colour coated steel and galvanised steel cladding avoid copper, lead, green or treated timber, stainless steel and mortar or concrete.
- Galvanised steel sheets should not receive drainage from aluminium or any inert materials, such as plastics, glass, glazed tiles, colour coated and zinc-aluminium alloy.
Stramit's roofing and walling products should be handled with care at all times to preserve the product capabilities and quality of the finish.
Packs should always be kept dry and stored above ground level while on site. If the products become wet, they should be separated, wiped and placed in the open to promote drying.
Stramit Sunset® Patio Panels are supplied cut to length. Manufacturing tolerance on length of product supplied is +0, -15mm.
Stramit products conform to the following Australian standards that are called up in the NCC.
Steel material
- All metallic coated steel complies with AS 1397
- Painted steel product conforms with AS 2728
Roofing / Walling products

Please refer to the Stramit Roof and Wall Flashing Architectural Detailing Design Guide.
The Patio roofing shall be 0.42 mm BMT Stramit Sunset® Patio Panel, in continuous lengths with ribs 43mm high, spaced at 290mm centres. Sheeting material shall be protected steel sheet to AS1397 with a minimum yield stress of 550MPa (Grade G550) and an AM100/AZ150 coating with an oven-baked paint film of selected colour, or a plain AM125/AZ150 coating.
The sheeting shall be fixed to the purlins in accordance with the manufacturer's recommendations. Suitable fixings in accordance with manufacturers instructions shall be used at every rib at every support. Sheets shall be laid in such a manner that the approved side lap faces away from the prevailing weather. A minimum of 50mm shall be provided for projection into gutters. Flashings shall be supplied in compatible materials as specified, minimum cover of flashing shall be 150mm.
All sheeting shall be fixed in a workman like manner, leaving the job clean and weathertight. Repair minor blemishes with touch-up paint supplied by the sheeting manufacturer. All debris (nuts, screws, cuttings, filings etc.) shall be cleaned off daily.

Screw fastening locations:
All fastening screws must conform to AS3566 – Class 3. They are to be hexagon headed and must be used with sealing washers.
Foot traffic limits for Stramit Sunset® Patio Panel are set for two alternative foot traffic categories:
- Light only: Maximum span for 0.9kN (controlled foot traffic, ie experienced personnel walking only on pans, based on AS1562-1992).
- None: Maximum span for 0.5 kN (loads applied via ladder or boards – minimum design value for roofs permitted by AS1170.1:2002).
Note: Walking on translucent panels in not permitted at any time.
Stramit Sunset® Patio Panel is manufactured from hi-tensile G550 colour coated steel or zinc-aluminium alloy coated steel. In some locations galvanised and severe environmental colour coated steel may be available by arrangement.
Colour coated steels are in accordance with AS2728 – Category 3 and, for the substrate, with AS1397. Zinc-aluminium alloy coated AZ150,aluminium-zinc-magnesium alloy coated AM100/125 and galvanised Z450 conform to AS1397.
A minimum roof slope of only 1 degree is required to ensure effective drainage. However, because the self-weight of the panels causes natural curvature, a minimum slope of 2 degrees applies to spans greater than 4 metres.
- Spans may be selected using the Span Chart or a combination of the Pressures and Foot Traffic tables.
- Design pressures assumed are 0.55 kPa for serviceability and 1.30 kPa for strength. This is suitable for regions A & B sheltered suburban and region A exposed suburban areas, N1 & N2 classification as per AS4055.
- Foot traffic and wind uplift deflection as per AS1562.1.
The tables below are based on 2 screws per panel. Alternatively, 4 aluminium rivets per panel may be used but the strength limit state capacities shown have must be reduced by 10%. 
Installation Information
Stramit's cladding can be easily cut, where required, using a power saw with a cold cut saw blade or a power nibbler and, for localised cutting, tin snips. Avoid the use of abrasive discs as these can cause burred edges and coating damage. Please dispose of any off-cuts carefully and thoughtfully.
Translucent panels should be installed in accordance with the instructions given in the Stramit Sunset® Patio Panel Technical Manual.
Below are some handy hints and tips to achieve maximum life from your COLORBOND® and ZINCALUME® finished products.
- In areas of little rainfall, products should be cleaned regularly.
- Brick cleaning acid should not come into contact with steel fascia, gutter, or roofing and walling.
- Never immerse these products in sand, soil or concrete.
- Do not use touch up spray can paint on COLORBOND® steel.
- Remove metal debris from cutting and/or drilling to avoid swarf damage.
- Prior to installation, keep bundled material dry.
- Prepainted metal roofing components should be stored in the shade as the protective plastic film will become difficult to remove if it is exposed to direct sunlight.
- Make sure materials made of different metal, such as copper and lead, do not make contact with these products, and water does not run from one to the other.
- Roofing and guttering should be free draining and free from dirt and leaves.
