Roofing bolts and nuts.Self-tapping screw with sealing rings and washers.

Washers minimum 32mm should be incorporated with the above fixings,complete with suitable sealing rings or washers.

Where sheets with corrugations over 25mm depth are fixed through the crowns to intermediate purlins.Shaped packing pieces should be located between the crown of the sheet and the support.

This should allow the fixing to tightened sufficiently without distance the profile of the sheet.

Fixing should not be located less than 50mm from the ends of sheets.

2.Side laps:

All side laps should be stitch (seam)bolted at maximum 300mm(12in)centers for roof pitches below 10 and maximum 375mm(15in) centers for roof pitches 10 and over.

In vertical cladding applications all side laps should be stitch(seam) bolted at maximum 450mm(18in) cenetrs.

3.End laps:

Minimum end laps,if unsealed,should be as follow:-

Below 15o roof pitch–not recommended .

Over 15o roof pitch–300(12in) lap.
