Allowable Roof Spans
The allowable roof spans for the S-RibTM Corrugated roofing profile in Regions C and D are shown in Table SR RS CY 001 and Table SR RS CY 002.
The allowable spans have been determined from tests carried out in accordance with AS4040.0-1992, AS 1170.2-2011 and the NCC (BCA) 2019 Specification B1.2 for the design of buildings in cyclonic areas.
Figure SR LPF CY 003
Note:
The local pressure factors (KL) are shown in Figure SR LPF CY 003 are not applicable at the ridge where the roof pitch is less than 10°. The value of ‘a’ is the minimum of 0.2 breadth, 0.2 width or the height.
Cyclonic Testing Wall Spans
Fielders® have undertaken cyclonic testing of S-RibTM Corrugated in accordance with the Low-High-Low cyclonic testing method in the NCC (BCA).
The cyclonic wind load capacities for S-RibTM Corrugated wall profile is shown in Table SR WC CY 002.

Allowable Wall Spans
The allowable roof spans for the S-RibTM Corrugated roofing profile in Regions C and D are shown in Table SR WS CY 001 and Table SR WS CY 002.
The allowable spans have been determined from tests carried out in accordance with AS4040.0-1992, AS 1170.2-2011 and the NCC (BCA) 2016 Specification B1.2 for the design of buildings in cyclonic areas.
Figure SR LPF CY 003
Note:
The local pressure factors (KL) are shown in Figure SR LPF CY 003 are not applicable at the ridge where the roof pitch is less than 10°. The value of ‘a’ is the minimum of 0.2 breadth, 0.2 width or the height.
Fixing of Cladding
Fasteners must be selected to match the life expectancy of the cladding material. Recommendations from fastener manufacturers should be sought. Only fasteners complying with AS 3566:2002 and those that are compatible with the roofing material should be used for its fastening.
All fasteners used externally should be fitted with an EPDM seal. Do not use punches to form fastener holes. Fasteners are fixed at alternate crests of the S-Rib Corrugated™ roof sheeting.
Pierce Fixing
Fasteners must be selected to match the life expectancy of the cladding material. Recommendations from fastener manufacturers should be sought.
Only fasteners complying with AS 3566:2002 and those that are compatible with the roofing material should be used for its fastening.
Notes:
All fasteners used externally should be fitted with an EPDM seal (washer). Do not use punches to form fastener holes.
S-Rib™ Corrugated Installation Procedure
For installation procedures see section "Typical Pierce Fix Installation Guide". For general handling instructions refer to section “Maintenance and Care”.
Side Lap Fixing
It may be necessary to use side lap fasteners at mid spans when using S-RibTM Corrugated at maximum spans. These will help to hold the sheet laps firmly in place and maintain a weather-proof joint.
Turning of Roof Sheeting Ends
Refer to section “Flashings, Cappings & Ends of Sheets”.
Maximum Sheet Length
See section “Thermal Expansion and Contraction of Steel Sheeting”.
Curving S-Rib™ Corrugated
For details regarding spring, crank and smooth curving of S-Rib sheets, please see section “Curving of Steel Decks”.
Curving quality corrugated is manufactured from G300 sub-strate (0.60 BMT). It is consequently more ductile, enabling specialist tradesmen using precision curving machines to form sheets to traditional heritage shapes and challenging architectural details down to radii as tight as 450mm. Fielders® have a dedicated roll forming machine for G300 thus avoiding any inconsistency arising out of changing over from G550 Hi-tensile coil.
