Australia's widest curved roofing

An innovative construction company, Spantech, has developed Australia’s widest self-supporting curved roofing panel. Architects have begun successfully applying the technology to large commercial projects such as sports centres and multipurpose halls, indoor swimming pools and large shade structures.

They all benefit from the expansive open space created when trusses and internal columns are eliminated from the design. The roof panels are roll-formed on site from pre-painted, colour-bond coil steel. The patented self-locking edge allows panels to clip together with a strong waterproof seal; no screws or bolts are needed. It is fast, simple and cost-effective.

The profile is initially rolled as a continuous straight panel. It is then curved to the required radius. The panels are used to create a distinctive self-supporting curved roof. There are two profile sizes available: one spans 30 metres, while the other   spans 40 metres. Acoustic and thermally insulated ceilings, plus a wide range of services, can be supporte
directly from the roof. Larger loads require lightweight structural members.

Spantech offers design assistance to help architects maximise the
benefits of their existing system. The privately-owned company was established in Australia in 1984 to design and construct buildings using the Spantech construction system, which features a site roll-formed construction panel with wide-span capabilities and a unique connection method.
