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.
Garden Designers & Landscapers Enjoy Working with Straightcurve®
Since launching in the UK in 2024, we’ve seen a steady increase in the number of garden designers and architects, including Arit Anderson, specifying Straightcurve and just as many landscapers selecting it for installation in their customer projects.
Why? Because of how simple and quick it is to install, for the amazing aesthetic it offers and it’s superb strength & durability.
Discover how garden designer Echo Cao of Echoes of Nature transformed a challenging sloping plot into an impressive landscaped garden at a new-build property in Henfield.
With stunning views across the South Downs, the project involved creating a series of flowing terraces and retaining walls to make the most of the garden’s natural contours. Using Straightcurve Flex, Echo brought the design together to create a beautifully considered outdoor space.
Explore the case study below to find out more about the project and how Straightcurve Flex helped bring the design to life.
