Strong, bold and stylish, Smartspan has a ‘square corrugated' form that provides an interesting blend of light and shade wherever it is placed. Smartspan has the looks and versatility to allow it to blend easily with any building style. Its strong nine rib design lends itself for use on roofing, walling and fencing. Smartspan is used on walkways, school buildings, or heavy duty walling in commercial and industrial applications. Smartspan is ideal for architects and builders who are trying to achieve a different look, with maximum serviceability.
Made from high tensile steel for strength and impact resistance, it is ideal for long length industrial uses. Smartspan can be used in continuous lengths, at low roof pitches with generous support spacings. This can provide a real cost saving on most projects. The 24mm high rib is strong and able to channel water quickly. It has a non-syphoning side lap which reduces the risk of moisture transfer between sheets due to capillary action, thus reducing the risk of roof leakage.
Custom made for your project
Smartspan sheets longer than 1.2 metres are rolled to the specific length you require, provided the appropriate transport and handling can be arranged. If lengths longer than ten metres are required, consult your nearest Stratco for advice on handling and transport.
To give your roof a professional finish, painted self drilling screws are available. Stratco offer a complete range of flashings and accessories for use with Smartspan, and can provide professional advice on specific flashings.
Design considerations
Smartspan has a 700mm coverage and the minimum recommended roof pitch is two degrees (1 in 30). Smartspan is subject to thermal expansion. Darker colours are affected more than light, and spring curved sheeting needs additional consideration. The maximum length before an expansion joint is needed is 24 metres for light colours, and 16 metres for dark colours. For spring curved sheeting it is 20 metres for light colours and 16 metres for dark colours.
Spring Curving
Smartspan may be spring curved using purlins at a maximum spacing of 1200mm for .42mm BMT and 1400mm for .48mm BMT. The curve must have a minimum radius of 20m for .42mm and .48mm BMT. The maximum radius is 60m to allow for sufficient drainage over a crest. The side laps must be sealed wherever the roof pitch is less than the recommended minimum.
Maintenance Requirements
The performance of Smartspan over time depends on its correct application and maintenance. Maintenance should be performed as often as is required to remove any dirt, salt and pollutants. Where used in severely corrosive environments, cleaning should be performed more often. It is important that screws have the same life expectancy as the cladding you have specified.
Compliance
The Wind Capacity Tables are based on testing in accordance with AS1562.1-1992 and AS4040.0, 1 & 2- 1992. Span tables have been developed by determining wind pressures in accordance with AS4055-2006 for domestic applications and AS/NZS 1170.2:2002 for all other applications. Capacity tables are in limit state format.
Ordering
Sheets are available custom cut, allowing you to minimise waste, and enhance your design options. Smartspan is available in un-painted zinc/alum, and in an attractive range of factory pre-painted colours. Subject to the delivery location, quantity and material availability, delivery is usually within 48 hours, or at an agreed time that suits your building schedule. Unless advised differently, a one tonne maximum is usually applied to larger packs. Arrangements for unloading the truck are the responsibility of the customer, and should be arranged before ordering. When unloading you must ensure the load is adequately spread using spreaders and slings to prevent damage. If packs are to be loaded directly above structural members, they must be of sufficient strength, such as over portal frames, or braced roof trusses.
