Box profile roofing sheets are fixed in the valleys, straight through the sheets. The seal is provided by a long life neoprene washer which will last up to 30 years.

The calculation for the number of fixings you will need is this:-

Number of fixing points x 4 (fixings per fixing point) x number of sheets

Fixings are supplied in bags of 100. Caps are available to suit the colour of the sheets you’ve chosen.

Fixings are available for fixing into 3 different types of material:-

1. Timber
2. Light Section Steel (up to 3.2mm thick)
3. Heavy Section Steel (up to 12mm thick)
