Testing
Stramit Minirib® Panelling 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 Minirib® Panelling is 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
- Roofing/walling profiles conform with AS 1562.1, and AS 4040 parts 0, 1, 2 and 3.
- Corrugated roofing conforms with AS 1445
- Wind Load data conforms to AS 1170 part 2, and/or AS 4055
- Fasteners conform with AS 3566
- Installation details are in accordance with the Standards Australia Handbook HB39
Stramit's roofing and walling products are protected in Australia by registered designs.
All Stramit roofing and wall cladding products conform with, or are equivalent to, AS1562.1.
Stramit has in-house, purpose built testing equipment used to design, develop and improve products for the Australian market. Many of our products are tested or witnessed by independent organisations. These include:
- University of Technology, Sydney
- Cyclone Testing Station (James Cook University)
- The University of Sydney, and
- CSIRO.
The ongoing research and development activity ensure we remain at the forefront of innovation, design and consumer information.

Please refer to the Stramit Roof and Wall Flashing Architectural Detailing Design Guide.
The cladding panels shall be 0.42 mm BMT Stramit Minirib® Panelling, in continuous lengths with ribs 4mm high, and a cover width of 900mm. 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 girts in accordance with the manufacturer's recommendations. Suitable fixings in accordance with Australian Standard AS3566, Class 3, shall be used as per manufacturers recommendations. Sheets shall be laid in such a manner that the approved side lap faces away from the prevailing weather. Flashings shall be supplied in compatible materials as specified, minimum cover of flashing shall be 50mm.
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.
A NATSPEC work section is available for this product. Download
For external applications, side lap fasteners are required at 200-300mm centres. At all supports, 4 equally spaced fasteners are required across the sheet including one fastener through or adjacent to the overlap.
For internal applications Stramit Minirib® panelling with spaces of 1000mm or more requires the side lap to be stitched at mid-span. For further installation information, refer to Stramit's Wall Sheeting and Cladding Product Technical Manual for your region:
All fasteners should conform with AS3566 – Class 3 and be compatible with the cladding material used.
For wall areas likely to be subject to human impact, sheeting spans should be reduced. Impact loads will vary considerably and these are not prescribed in Australian Standards. A maximum span of 900mm is suggested for such areas, but this should be adjusted dependent upon the exposure and importance of the application.
Stramit Minirib® panelling is manufactured from G550 colour coated steel or zinc-aluminium alloy coated steel. In some locations galvanised and severe environment 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/AM125 and galvanised Z450 conform to AS1397.
Stramit Minirib® Panelling is not suitable for roofing.
Stramit Minirib® panelling can spring curved to a radius as tight as 2000mm for additional architectural versatility. However, at radii of 6000mm or less the support spacing must be reduced to no greater than 600mm.
Derived from testing, the following tables give the wind load resistance for both serviceability and strength limit states. 
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.
Do not overtighten screws and ensure they are kept perpendicular to the sheet during installation.
For maximum protection from weather intrusion vertical sheets should be laid with the exposed edge of the overlaps away from the direction of the prevailing weather.
Horizontal or diagonal sheets must be laid with the exposed edge of the overlap at the bottom of each sheet. Horizontal or diagonal sheets will also require a suitable under flashing as some rainwater may run or be blown to the sheet ends.
Installation is a straightforward procedure using the following fixing sequence:
- Ensure all girts or wall frame studs are in line, correctly installed and that the lining materials (if specified) are in place.
- Position and fix the first sheet ensuring the correct sheet overhangs (minimum 50mm from the edge fastener).
- Continue to fix subsequent sheets checking that sheet ends at the lower edge are exactly aligned, and that sheets sit correctly so that the integral anti-capillary space is effective. Measure the overall cover width at top and bottom of the sheets from time to time to avoid 'fanning'.
- Stitch the side laps at midspan for wall spans specified for each product.
- Install flashings.
- Clean up after each days work, removing all screws, cuttings, swarf etc, and leave clean and watertight.
Note: additional fasteners do not allow greater spans.
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.
