A sprung cured roof can be concave or convex, a combination of concave and convex, or a combination of straight and curved as long as it’s within the practical limitations of the steel.

Sprung curved roofing is the process of free forming the roof sheet over the contours of the roof frames, progressively fixing the individual sheets to the battens (or purlins). The finished curved form being totally dependant on the correct alignment of the batten fixing points of the roof framing – much like stretching modern camping tents over the correctly positioned tent frame struts.

The main advantage of sprung curved roofs is that standard corrugated steel sheets made from COLORBOND® and ZINCALUME® steel can be used- delivered to the building site in straight flat sheets. Consequently sprung curved steel roof sheeting in this regard is no more costly.

In designing a sprung curved roof it is important to work within the curving range of the steel. For standard corrugated sheeting made from COLORBOND® and ZINCALUME® steel, concave curve must have a radius of no lower than 12m and a convex roof of a radius of no lower than 10m.

As a result, of these design parameters the sprung curved technique lends itself to soft sweeping curves.

For tighter convex or concave radi, sprung curving cannot be used, rather, factory pre-formed curved corrugated sheeting must be used. It is important to note that curved roofs do require a different approach to roof frame construction than that of normal pitched roofs and that any extra cost differential can be minimised through having correct information at the design stage.

Several steel roofing suppliers have produced comprehensive guides to installation of curved roofs covering various aspects of installation and design principals. There are also other roof deck profiles, than the standard corrugated shape, which have different curving abilities - steel roofing suppliers will also be able to assist in providing this information.
