Fielders Steel Roofing supplied their standing roof profile, FreeForm for the curved roof above the $197.5 million redeveloped pavilion at the Sydney Cricket Ground.

Designed to provide 85 per cent coverage for the new seating area, the curved roof achieved with Fielders’ FreeForm profile was perfectly aligned with the ‘helmet’ style outline of the canopy, helping create a striking effect for the world-class sports and recreation facility.

The redevelopment of the MA Noble and Donald Bradman stand at the Sydney Cricket Ground (SCG) was completed in July 2014 to provide an additional 13,360 seats for the ground.

Fielders was contracted by AW Edwards Pty Ltd and Cox Architects to provide a roofing solution for the large canopy of the new pavilion. Given the complexity of the design brief, which sought a solution for the unique curved shape of the pavilion’s roof, the highly flexible FreeForm standing seam profile was selected for the project. The roof was to be sprung curved in both directions creating convex radii from 120m in the centre, and curving down to 55m at both ends. The installation relied on the flexibility of the FreeForm system to create the natural curves required to synthesise with the ‘helmet’ style outline of the canopy.

The project utilised over 5,000m² of tapered Surfmist COLORBOND FreeForm 0.75mm BMT with the material tapered from 380mm down to 220mm to meet the natural curves of the structure.

The Fielders mobile roll-former was based on-site at the SCG to roll 450 individual FreeForm sheets to assist with a faster turnaround. The materials were hoisted by a crane to the top of the pavilion using a 48m spreader bar, with the whole process taking 20 days from start to finish.

Fielders also provided the soffit lining to the underside of the structure, which was fitted in the S-Rib profile to complete the project.

Part of the standing seam family of architectural roof cladding profiles available from Fielders, FreeForm offers the flexibility to create shapes and curves that existing profiles on the market are unable to replicate. Suitable for diverse roofing configurations thanks to its versatility in curved applications, FreeForm can be convex or concave curved vertically or horizontally, allowing a broad range of architectural designs to be realised.

FreeForm roofing profiles can be used for standard purlin construction, single skin roof applications, vertical wall, conical tapered roof profiles, structural deck and cassette type roof applications, re-roof framing and plywood substrate roofing situations.
