General Information close-medium-white

SUPERDURA® Stainless coated steel should not be installed in contact with non-galvanised steel, copper, brass, lead or monel metal. Do not use lead flashing with SUPERDURA® stainless coated steel. SUPERDURA® stainless coated steel should not be installed in contact with non-galvanised steel, copper, brass, lead or monel metal. Do not use lead flashing with SUPERDURA® stainless coated steel.

If nestable profiles become wet while closely stacked, formation of wet storage stain or ‘white rust’ is possible. To minimise the possibility of inadvertent damage:

  • Inspect deliveries on arrival. If moisture is present, individual sheets should be dried immediately with a clean rag and then stacked and filleted to allow air to circulate and complete the drying process.
  • Well ventilated storage is essential. Always store metal products under cover in clean, well-ventilated buildings.
  • Cross stack or fillet sheets where outside storage is unavoidable and make provision for a fall to allow water to run off.
  • Cover the sheets.

The substrate under the paint film is grade 430 stainless steel. The colour coat complies with AS2728.

SUPERDURA® products are not suitable for use in the following situations:

  • for water tanks or areas where a constantly wet environment is maintained
  • in direct contact with concrete or where lime deposits are evident, or
  • in contact with soil (allow a 75mm run off below cladding sheets to ground level)

SUPERDURA® products cannot be soldered.

Technical Information close-medium-white

SUPERDURA® products under normal well washed conditions of exposure, can be expected to show no cracking (other than that which may occur during forming), flaking or peeling of the paint film for 15 years from the date of installation. Colour change during service will depend on the colour chosen, aspect, design of the structure and the environment.

Class 5 fasteners are recommended for outside conditions when using SUPERDURA® coated materials.

  • The steel base is manufactured to meet relevant Australian Standards, ensuring strict adherence to the required grade and strength.
  • A thin pretreatment layer is applied to optimise the adhesion of further coatings.
  • A corrosion inhibitive primer is baked onto the surface.
  • A topcoat of specially developed, exterior grade paint is baked on to provide resistance to chipping, flaking and blistering and to ensure the finish retains its look for longer.

To ensure appropriate quality products are used in construction, comprehensive specifications from Stramit's relevant Product Technical Manuals should be included in the design documentation, including reference to SUPERDURA® material.

Installation Information close-medium-white

SUPERDURA® material can be easily cut, where required, using a power saw with a steel cutting 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.

Please refer to the SA HB 39:2015 Installation code for metal roof and wall cladding for correct installation guidelines, particularly in regard to underlays/building papers, penetrations, flashings, fasteners and pitch.

Maintenance Information close-medium-white

The service life is extended by regular washing. A mechanical wash every six months is recommended, more often if contaminants build up. At these times inspect for damage and failing fasteners, and repair these.
