Note: For Stratclad design parameters and span definitions, please refer to the Engineering notes at the beginning of the Roofing and Walling section.

For Region C and D fixings refer to ‘Cyclonic Cladding’ within the roofing and walling ‘Cladding’ section of the Stratco website.

Note: The following recommendations apply to non-cyclonic areas.

  • All fasteners must have neoprene washers to prevent water penetration.
  • Side lap fixing is recommended at no greater than 300mm centres for external applications. For internal applications where support spacings exceed 1000mm it is recommended side laps are fastened mid-span. 
  • Use either 8x12mm self drill stitching screws (with seal) or 3.2mm sealed blind rivets.
  • If fixing over an insulation blanket the next standard screw length to that indicated may be required with minimum 25mm timber embedment to be maintained.
