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.

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:
1. All fasteners used externally should be fitted with an EPDM seal (washer). Do not use punches to form fastener holes.

Side Lap Fixing

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 weatherproof joint. Use 10g-12x20mm Needle point hexagon head self-drilling stitching screws.

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 NC 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 NC 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.

Spanform™ Installation Procedure

For installation procedures see section “Typical Pierce Fix Installation Guide”. For general handling instructions refer to section “Maintenance and Care”.

 

Turning of Roof Sheeting Ends
