About Mini-Flute

Offering versatile characteristics, Mini-Flute allows for maximum design freedom. The traditional ‘S’ profile maintains a heritage look and in contrast also works as an attractive cladding option on ground breaking architecturally designed buildings. It’s ability to be used vertically, horizontally or diagonally opens a range of stunning design options. While full-length sheets and wide coverage allow for quick installation.

Fielders® Mini-flute is available in COLORBOND® steel, ZINCALUME®, Heritage Galvanised and Stainless Steel, allowing the flexibility to create a modern appearance through to a rustic look.

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.

Mini-Flute Installation Procedure

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

Perforated Metal

Mini-Flute is also available in 0.48 BMT ZINCALUME® steel (conforming to AS 1397:2001 G550-AZ150) or in COLORBOND® steel (conforming to AS 1397:2001 G300- AZ150) with 2.38mm diameter holes at 6.74 pitch, providing 11% open area. Other materials and gauges with different hole sizes and pitches are also available.

Mini-Flute is also available in 0.42 BMT G550 and 0.60 BMT subject to minimum order quantity and appropriate lead time.

Maximum Sheet Length

Curving Mini-Flute

Mini-Flute can be curved by hart curving down to a radius of 500mm in either 0.42 BMT, 0.48 BMT or 0.60 BMT to form sheets to traditional heritage shapes and challenging architectural details.

For details regarding spring and smooth curving of Mini-Flute sheets, please see section “Curving of Steel Decks”.
