Straightcurve® is available in two finishes; Weathering Steel and Galvanised Steel
Weathering Steel
Weathering steel (sometimes referred to as Corten steel), is an intentionally oxidised steel alloy. It forms a stable, protective layer of rust when exposed to the elements, eliminating the need for painting while providing long-term structural durability.
Unlike standard carbon (mild) steel, which continues to rust until it degrades structurally, weathering steel creates a dense surface oxidation layer (a patina). This patina seals the underlying metal from moisture, oxygen, and atmospheric pollutants ensuring structural integrity for decades, even in damp environments. Refer to the Straightcurve® longevity guide for more information.
Galvanised Steel
Protected by a hot-dip zinc coating, galvanised steel offers superior weather resistance and long-term durability without ever requiring a coat of paint. Where standard carbon steel breaks down through destructive rusting, galvanised steel relies on sacrificial protection—the zinc shell corrodes in place of the base metal, continuously sealing it against dampness, air, and soil pollutants. The result is total structural integrity built to last for decades.
This finish is also suitable for painting and powder coating, allowing you to customise your Straightcurve® installation.
