A large amount of corrugated steel profile sheets and GRP roof lights are constantly kept in stock for the 3″ corrugated available in lengths up to 24ft/7.3m. Standard lengths for the the corrugated are 6ft, 8ft, 10ft and 12ft. All roof lights can be cut to exact length. The advantage of replacing some of the steel sheets with our GRP roof lights are letting natural day light in saving costs such as electricity.
When fitting our 3″ Corrugated the fixing is to be put through the top of the profile with one of our self tapping tek screws with the water sealant washer. The standard length of fixing should be approx 45mm to allow for the profile of the sheet and then to allow a solid fix into the perlin.
