Applications

The visual appeal, strength, wide cover, light weight and weather resistance of Stramit Speed Deck Ultra®decking make it perfect for all commercial roofing applications. Its excellent strength and ease of assembly allow for long, economical spans.The large water-carrying capacity and weather-tightness permit very low roof pitches, leading to economies in the building structure.

Stramit Speed Deck Ultra® decking may also be used for domestic applications.

Materials

Stramit Speed Deck Ultra® decking is manufactured from hi-tensile G550 colour coated steel or zinc-aluminium alloy coated steel. In some locations galvanised and severe environmental 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 and galvanised Z450 conform to AS1397.

Overlapping Roof Sheets

For long run roofs that exceed the maximum recommended sheet lengths, and for awkward sites where trunk or crane access is limited, the Stramit Farlap® roof lap joint system is available. This enables overlapping sheets to be simply and reliably attached without the need for a traditional step joint. The roof support structure can be designed and fixed in a single plane. Refer to Stramit Farlap® roof lap joint system product technical supplement for full details of the product.

Compatibility

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:

  • For zinc-aluminium alloy coated steel, colour coated steel and galvanised steel roofs avoid copper, lead, green or treated timber, stainless steel and mortar or concrete.
  • In addition galvanised steel roofs should not receive drainage from aluminium or any inert materials, such as plastics, glass, glazed tiles, colour coated and zinc-aluminium alloy.
