Nail Fastening to Timber Trusses

Rafter Spacing (centre to centre for steel cladding)
Wind Category	600mm c/c	900mm c/c	1200mm c/c
W33 (N2)	1800mm c/c	1500mm c/c	1200mm c/c

Notes:

This information should be used only in domestic buildings with metal clad roofing and softwood timber (pine) trusses.
Nail Pull Out tests were conducted at Lysaght Technology's NATA-accredited materials science testing laboratory and these results determine the allowable spacing for nail fixed battens.
Nail tested was 2 x Duo-Fast S3.1 x 65 (D30300) 65mm long round head.
2 nails per joint is suitable for tile roofs.

For pine 2 off 12 - 11 x 30mm self tapping screws for wood per joint or 2 -11 x 25 self tapping screws for wood per joint for W28N, W33N and W41N
For wind categories W28, W33, W41 - minimum Truss chord material 1.0 BMT - 2 off 10 - 16 x 16*
W50 & W60 - minimum Truss chord material 1.2 BMT- 2 off 12 - 14 x 20*
W70 - minimum Truss chord material 1.6 BMT - 2 off 12 - 14 x 20*
For sheet roof applications, batten connections to the chord of the first truss in from the gable end should be strapped if the batten spacing is less than 1400mm and the truss spacing is 450mm. Strapping shall be 1.0 x 25mm fastened to the web of the truss chord with 2 off 10 - 16 x 16 Hex. Self-drilling screws.
* Hex. Self-drilling screws

1 off 10 - 16 x 16 Hex. Self drilling screws per joint alternating top and bottom. Use 2 per joint at free ends.

12 gauge type, 17 or 12-11 reduced drill point as per standard BlueScope Lysaght recommendations
