Stramit Speed Deck Ultra® Concealed Fixed Decking

Stramit Speed Deck Ultra® is a high performance, 700mm wide cover, concealed fixed roof decking with a patented rail-clip fixing system.


  • Wide Cover – fewer sheets and quicker installation
  • Deep Ribs – stronger with better water carrying capacity; roof slopes as low as 1°
  • Full Length Clips – to locate ribs and compress insulation
  • Four Fixing Points Per Clip – with centralised fastening for unsurpassed strength.
  • Hexagon Head Screws – bigger, stronger and easier to install, with less wastage
  • Outstanding Wind Load Resistance – improved security with lower purlin costs
  • Spring Curving – data for arched and curved roofs
  • Automatic Bird Proofing – built in accessory with no need for extra components


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 section 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.
