Box profile roofing sheet offers a coating of Aluminum-Zinc protective alloy on a carbon steel base which is pre-painted in controlled factory conditions. It offers consumers the benefit of a box profile with an effective cover width of 1015mm. When using Box Profile sheeting the recommended minimum pitch for roof slopes in excess of 15m is 10º and for slopes less than 15m is 7.5º.

During Installation it is recommended that you lay each run of sheets in turn from side to side before moving onto the next run as depicted below. Similar procedure for wall cladding too. Screws must be used in conjunction with appropriate washers. Alternative option is to install using traditional galvanized twisted shank roofing nails hammered into place using appropriate UPVC caps and washers.
