Stramit Monoclad® Roof and Wall 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 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 0.42 (or 0.48) mm BMT Stramit Monoclad® Roof and Wall Cladding in continuous lengths with trapezoidal ribs approximately 29mm high, spaced at 190mm centres. Sheeting material shall be protected steel sheet to Australian Standard 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/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. 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 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 Monoclad® Roof and Wall Cladding can be found in the Stramit Cyclonic Areas Guide.
Information on the use of Stramit Monoclad® Roof and Wall Cladding Roof Cladding can be found in deemed-to-comply sheets No’s M/148/01, M/103/03 and M/104/04. These are available from Stramit or on the NT BAC website.
Stramit Monoclad® Roof and Wall Cladding can be fixed with 4 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 approved system consists of Stramit® Monoclad Roof and Wall Cladding, 762mm effective cover sheets produced from hi-tensile steel with class AZ coatings to AS1397 in plain or pre-painted finish.
The sheet must be secured using either Buildex Auto Teks® M5.5-14 x 50mm or Buildex Roof Zips® M6-11 x 50mm screws at each crest.
Where side laps are recommended, they must be Buildex® No 8-15 x 15mm hex-head screws and should be used at every lap joint of sheeting at midspan only.
Cyclone assemblies are Buildex Square-Lok® cyclone assemblies with No 14-10 x 50mm hex head screws. All steel supports should be a minimum of 1.5mm thick.
Achieved Ratings for Each Assembly:
Please refer to the Stramit Roofing Systems with FM Approved Certification brochure for more details.
Stramit Monoclad® Roof and Wall Cladding is manufactured from hi-tensile G550 colour coated steel, aluminium-zinc-magnesium 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 – Category3 and, for the substrate, with AS1397. Aluminium-zinc-magnesium alloy coated AM100/AM125, zinc-aluminium alloy coated AZ150 and galvanised Z450 conform toAS1397.
The minimum roof slope for Stramit Monoclad® Roof and Wall Cladding is 2 degrees (1 in 30)
The spans shown below take account of normal foot traffic and wind resistance including local pressure zone effects. Pressures are based on AS4055 or AS1170.2 .
Where the two standards differ, the worst case has been taken for each classification. Data should only be used for buildings 7m or less in height, 1000m2 or less in area and unaffected by land topography.
Stramit Monoclad® Roof and Wall Cladding can be spring-curved, concave or convex, including curved ridges, provided it is sealed at the apex, and within the recommended limits below. The Stramit Spring Curving Guide provides more detail.
All metal roof sheeting is subject to thermal expansion and, where there is a temperature difference between the sheeting and the structure, this needs to be accommodated. The colour of the sheeting will affect the amount of thermal expansion, and whether the sheet is flat or curved will affect its ability to resist without problems.
Sheet lengths should be limited to:
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 Monoclad® Roof and Wall Cladding is readily installed with or without a fibreglass insulation blanket. If practical, lay sheets in the opposite direction to prevailing weather.
Installation of Stramit Monoclad® Roof and Wall Cladding is a straightforward procedure using the following fixing sequence.
The Stramit MonoLap® roof lap joint is a revolutionary system (patent pending) that changes the way long run roof cladding is designed and installed. It provides a multiple sheet option for long length screw fixed roofing projects that eliminates traditional step joints or the need for long on-site rolled sheets, without compromising the integrity of the roofing structure.
Designed specifically for Stramit Monoclad® Cladding, the Stramit MonoLap® roof lap joint system allows the installation of lapped sheets on standard purlin framing, without the need for conventional stepped jointing. The system provides a combination of a strong joint and a weather-resisting seal between lapped sheets.
The system is simply installed by placing onto the bottom sheet with enlarged holes in the ribs. The top, overlapping sheet is then placed over the Stramit MonoLap® units, and screwed through both layers to the support below. The joint connectors and sealing foam are manufactured from high technology materials that provide strength and weather-resistance and preserve the existing roofing warranty.
Stramit MonoLap® roof lap joints can only be used with Stramit Monoclad® Roof Cladding and with the following provisions:
For detailed information refer to the Stramit MonoLap® Product Technical Supplement.
Stramit MonoLap® lap joints are readily installed on Stramit Monoclad® Roof Cladding. Stramit Monoclad® Roof Cladding sheets are installed in the normal manner, except that:
When installing the Stramit MonoLap® units:
For use in conjunction with the Stramit MonoLap® Roof Lap Joint System, the Stramit MonoSky® joint is only suitable for the fibreglass over fibreglass joint and the edge joint of the fibreglass over the Stramit Monoclad® sheeting.
Fibreglass sheet overlaps should be a minimum of 350mm as per the Stramit MonoLap® Product Installation Supplement. For full installation instructions refer to the Stramit MonoSky® Joint System Installation Supplement.
As with all roofing products, we recommend extra caution be taken when walking on the roof. When walking on Stramit Monoclad® Roof and Wall Cladding 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.
