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:
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.
Roofing / Walling products
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:
The ongoing research and development activity ensure we remain at the forefront of innovation, design and consumer information.
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.
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.
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:
Note: additional fasteners do not allow greater spans.
