It is important to select the correct fasteners for your application. This information can be contained from one of the Steelformers sales representative or Konnect, our fastener supplier. The NZMRM Code of Practice also provides information on selection, fixing methods and patterns according to wind zones. It is important to ensure the fasteners are 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.



Please note:
*Long spans may require the specification and use of side lap stitching screws
*Fixing aluminium roofing requires a 10mm oversized pilot hole
*Aluminium wall cladding can be pan fixed up to 8m, then crest fixed with washers and EPDMs for 4m (limited to a maximum of 12m)

As per the current NZMRM Code of Practice, compliance with E2/AS1 is dependent on the purlin spacing and gauge of material.


Recommended fixing patterns for residential applications for 0.40mm BMT roofing iron is as follows:

Fix every second crest with approved screws (and load-spreading profiled metal washers and EPDMs if required)





Top and bottom row: Fix every crest with approved screws (and load spreading profiled metal washers and EPDMs if required).
Internal supports: Fix 2 crests, miss 1, fix 1, miss 1 and repeat



*NZMRM Code of Practice 3.14.4 – Patterns
*NZMRM Code of Practice 3.14.5 – Wind Zones


*Maximum spans for Styleline with a 1kN concentrated load of G550 steel
*These should be reduced in high foot traffic areas or positioned to suit specific locations i.e. windy areas
