Spring Curving

Stratco manufacture continuous lengths of roof sheeting that can be laid from eave to eave across the full width of the roof. The following precautions should be considered for this type of roof construction:

• Roof slopes for each of the roofing profiles shown in Tables on the Technical Information tab are not to be exceeded.
• Spacing between the ridge purlins are as shown in Tables ob the Technical Information Tab.
• Where a ridge board is used in the roof construction the top face should not be higher than the line of curvature that the roof sheeting will assume between the ridge purlins.
• Side laps are to be sealed along the full length of the curvature, between the two centre purlins.
• Slight crease marks may occur in the pans of the roof profile between the ridge purlins or roof battens when subject to foot traffic.
