Sheets should be secured using our zinc plated bitumen fixing nails. Two rows of nails should be driven in parallel to the direction of the head and at each side of the sheet. Nails should be driven in to the crown (the uppermost part) of the sheet. Subsequent rows of nails should be used every third corrugation.
