8.13 - Fixing specification

Back to main Contents page

The fixing options selected depend on the function they perform and supports to which they are being installed.

Hot Rolled Steel Sections:

• Shot-fired Hilti X-ENP-19 L15

• 5.5mm carbon steel drill screws, or stainless steel for more aggressive environments

Cold-formed Steel Purlins:

• 5.5mm carbon steel drill screws, or stainless steel for more aggressive environments

Timber and/or Glulam Beams:

• 6.5mm stainless steel screws

Side stitching of sheets and/or flashings:

• 4.8mm carbon steel drill screws, or stainless steel for more aggressive environments

Note: The above fixing types and centres (from Table 8.14a) will need specific checks for any uplift or diaphragm design required. This may result in a different fixing type or spacing being required to suit the design situation. For all fixing checks carried out, the performance data for the fixings should be tested in accordance with ECCS publication No. 124.
