Stramit CapacityPLUS™660 Deep Roof Cladding 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's cladding is suitable for use with insulating blanket. Glasswool blanket up to 50mm thick can be readily used. Increased thicknesses require longer fasteners and greater care in installation. For domestic applications Stramit recommends that insulation is always used. Contact us for further information.
Stramit CapacityPLUS™ 660 Deep Roof Cladding is supplied cut to length. When designing or transporting long products ensure that the length is within the limit of the local Transport Authority regulations.
The manufacturing tolerance on the 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 roofing/walling shall be Stramit CapacityPLUS™660 Deep Roof Cladding in continuous lengths with trapezoidal ribs approximately 50mm high, spaced at 220mm centres.
Sheeting material shall be 0.42mm (or 0.48mm) bmt G550 protected steel sheet to Australian Standard AS1397, with a minimum yield stress of 550MPa (Grade G550) and an AM100/AZ150 or ZM275 coating with an oven-baked paint film of selected colour, or a plain AM125/AZ150 coating.
The sheeting shall be fixed to the purlins/girts in accordance with the manufacturer’s recommendations. Suitable fixing screws in accordance with Australian Standards AS3566, Class 3, shall be used at every rib at every support with side lap fasteners installed at mid span if required. A minimum length 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 weather-tight. Repair minor blemishes with touch-up paint supplied by the roof manufacturer. All debris (nuts, screws, cuttings, filings etc.) shall be cleaned off daily.
Class 4 fasteners should be used <1km from the coast.
Cyclonic data for Stramit CapacityPLUS™660 Deep Roof Cladding can be found in the Stramit Cyclonic Areas Guide.
Information on the use of Stramit CapacityPLUS™660 Deep Roof Cladding in the Darwin area can also be found in deemed-to-comply sheets No M/147/01. This is available from Stramit or on the NT BAC website.
Stramit CapacityPLUS™660 Deep Roof Cladding can be fixed with 3 fasteners per sheet at each batten/purlin to meet the required performance values.
All external fastening screws must conform to AS3566 – Class 3. They are to be hexagon headed and must be used with sealing washers for both roofing and walling.
For connecting to purlins or top hats use:
The Stramit Cyclonic Areas Manual has fixing details for cyclonic areas.
Foot traffic limits for Stramit CapacityPLUS™660 Deep Roof Cladding Stramit are shown for 3 alternative foot traffic categories:
High Maintenance – for applications with repeated maintenance, particularly where personnel may be unfamiliar with correct procedures for walking on metal roofs.
Normal – based on traditional expectations, with moderate maintenance foot traffic using designated footpaths.
Controlled – spans that confirm to AS1562 but require minimal careful foot traffic only on the designated footpath. Suggested for use only where occasional aesthetic imperfections from foot traffic are acceptable.
For more information on foot traffic performance of Stramit's roofing profiles refer to Stramit's Foot Traffic Guide where tables are based on tests to AS1562 and AS4040 parts 0 and 1.
Stramit CapacityPLUS™660 Deep Roof Cladding 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.
The minimum roof slope for Stramit CapacityPLUS™660 Deep Roof Cladding is 1 degree (1 in 60)
Stramit CapacityPLUS™ 660 Deep Roof Cladding can be spring-curved, concave and convex, including curved ridges, provided it is sealed at the apex, and within the recommended limits below.
The Stramit Spring Curving Guide has more detailed information.
All metal roof sheeting is subject to thermal expansion and this needs to be accommodated where there is a temperature difference between the sheeting and the structure.
The colour of the sheeting will affect the amount of thermal expansion, and whether the sheet is flat or cured will affect its ability to resist without problems. Sheet lengths should be limited as follows.
Stramit CapacityPLUS™660 Deep Roof Cladding has excellent water-carrying capacity. This and the sheeting stiffness enable roof slopes to be as low as 1° for many applications.
Roof run lengths are the combined lengths of all roof elements contributing to a single pan drainage path. This can include the roof length upstream of a roof penetration that concentrates flow into other pans.
The table below gives slopes for 100 year return period rainfall intensity.
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.
Stramit CapacityPLUS™660 Deep Roof Cladding is readily installed with or without fibreglass insulation blanket. If practical lay sheets in the opposite direction to prevailing weather.
Installation of Stramit CapacityPLUS™660 is a straightforward procedure using the following fixing sequence.
As with all roofing products, we recommend extra caution be taken when walking on the roof. When walking on Stramit CapacityPLUS™660 cladding roofing always wear flat rubber soled shoes and place feet only in the pans, taking care to avoid the last pan or two near edges of the metal roof area. Walk only in pans, or on ribs at purlin supports.
