INTRODUCTION
When fixing to steel battens/purlins, the fixing capacity of a roof screw depends on the thickness of the batten. This affects the fixing spacing. The installation drawings in the SunLock installation manual are “one size fits most” with the batten assumed to be 0.75 mm thick. For sites with battens of a different thickness, please refer to the attached letter from Dome Consulting (Aust) Pty Ltd to determine how to alter the fixing spacing.
