Stockwell specified roofing made from COLORBOND® Metallic steel in the colour Axis®, in Stramit Longspan® profile, and reports that it was relatively easy to install. Indeed, the gentle sine curve of the roof allowed the project to be constructed using straight materials in short lengths, which reduced the complexity of the build and dispensed with having to get items purposefully bent.
The top and bottom of the roof were plotted as a series of points in space and the steel structure, made from prefabricated 100 UC and 200 UB steel members, was bolted together. The builder then placed the rafters and timber battens on top.
