Fitting Tips

A minimum slope of 5° is essential in any structure to ensure water run-off: 10° or more is preferred.
Sheets should overhang the roof by minimum 60mm to allow rainfall to run-off and should be wide enough to cover the barge board at the side.

Fixing Sheets
When fixing sheets with galvanised self drilling screw, it is recommended to fix through the highest point of the profile to permit free drainage when used in roofing applications.
Number of Fixings Required
Divide the roof width by the fixing centres.
Divide the roof length by the support centres +1.
Multiply these two values together
=approximate number of fixings required.

Cutting Sheets
If cutting is required use an angle grinder with a metal slitting blade or fine toothed saw or nibbler tool, caution should be used when cutting metal sheets, appropriate PPE should be worn.
Support the sheet to minimalize vibrations.
Always take appropriate safety precautions and wear personal protective equipment when handling, installing and cutting this sheeting.
If a sheet needs to be cut at a finished width, make the cut in the downward slope of the corrugated sheet.

Joining Sheets
If the sheets need to be joined end to end, ensure an overlap of at least 300mm.
Use a strip of Butyl tape to prevent dust and dirt getting between the sheets.
It is advised when fitting roof sheets to ensure that they are overlapping by at least one corrugation and to work from left to right on a building when installing.
