Fastenings & Fixings
It is important to select the correct fasteners for your application. The fasteners must be class 5 minimum, their durability is at least equal to the durability of the material and all screws have a neoprene washer and in some cases a load-spreading washer and EPDM.
The NZMRM Code of Practice provides information on selection, fixing methods and patterns according to wind zones.
The following chart shows the maximum permissible purlin spacing (span) for NC710 G550 (under 1km concentrated load).
These should be reduced in high foot traffic areas, areas supporting items such as air conditioning units or positioned to suit specific locations e.g. high wind zones.
