Thermal Expansion Gaps for Aluminium Channels
For metal roofs we recommend using a minimum screw fixing space of 600mm when fixing
the aluminium angle. Depending on your wind loading (see “Wind Proofing” section), angle of
install, you may require a higher density of fixings and/or a stronger Aluminium angle, if
unsure please seek advice.
