Spanform™ Cyclonic

About Spanform™

Spanform™ is the multi-rib and multi-purpose roofing and walling panel from Fielders®. Offering impressive spanning qualities and optimum durability, Spanform™ provides the flexibility you need to design and build a variety of steel projects. Using innovative design, Spanform™ has higher and squarer ribs to provide its impressive strength. Despite being similar to corrugated steel in appearance, Spanform™ can achieve much more as a steel roofing and walling product. Available in long lasting ZINCALUME® and COLORBOND® steel, suitable as either roofing or walling product.

Cyclonic Testing

Fielders® have undertaken extensive and comprehensive testing on our roofing profiles for cyclonic regions. The following tables provide wind capacities and span values for the SpanformTM roofing profile in cyclonic region.

The cyclonic wind load capacities for SpanformTM roofing profile is shown in Table SF WC CY 001 below.

 

Figure SF CY 002 End Spans, Internal Spans and Overhangs illustrates the terminology end spans, internal spans, and overhangs and their reference to the supporting substructure. This terminology has been used in the following Maximum Recommended Span and Wind Load Capacity tables.

Allowable Roof Spans

The allowable roof spans for the SpanformTM roofing profile in Regions C and D are shown in Table SF RS CY 001 and Table SF 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) 2016 Specification B1.2 for the design of buildings in cyclonic areas.

Spanform™ CYCLONIC Figure SF CY Local Pressure Factors 002

Figure SF CY Local Pressure Factors 002

Note:
The local pressure factors (KL) are shown in Figure SF CY Local Pressure Factors 002 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 SpanformTM roof sheeting.

Spanform™ CYCLONIC Pierce Fixing

Side Lap Fastening

Side lap fasteners may be necessary at mid spans for purlin spacings over 900mm and girt spacings over 1200mm to hold the sheet laps firmly in place and maintain a weather-proof joint. Use 10x16mm Hex Head Tek Screws with Neo washers.

Note:
Do not use punches to form fastener holes.

Insulation

Care needs to be taken when installing insulation with roof sheeting. When insulation thickness up to 50mm are installed the screws detailed in Table SF PF CY 001 may need to be increased depending on the thickness and density of the insulation. When the screw is properly tightened into metal there should be a minimum of three (3) threads protruding past the support being fixed in to. For timber the screw must penetrate the timber as much as the screws detailed in Table SF PF CY 001 do without insulation.

For insulation thicknesses greater than 50mm Fielders® recommend the use of a thermal spacer to help maintain Rw values as well as minimising any bulging in the profile caused by the insulation.
