Curving Quality

A traditional sheeting with modern applications, curving quality adds an attractive feature to any building whilst preserving strong, clean lines.

Corrugated Curving sheets can be pre-curved by Queensland Sheet Metal into a variety of forms to produce concave or convex curves, bullnose roofing, or barrel vaulting, in either concave or convex arrangements.

Types of Curving

Available Colours

The Colorbond® steel colour swatches above have been reproduced to represent actual product colours as accurately as possible. However, we recommend checking your chosen colour against an actual sample of the product before purchasing, as varying light conditions, different screens and limitations of the printing process may affect colour tones.
