Corten cladding presents a new twist on an old theme with modernist steel cladding that has a touch of the traditional values of rugged endurance. Corten weather resistant steel forms a protective anti corrosion layer over time.

This rich reddish-brown rusted protective layer will provide anti-corrosion properties that are even superior to those of ordinary steel in many applications. The richly hued patterns of Corten steel can transform any building and work especially well as feature walls in contrast with other cladding types such as stone or timber.

Corten cladding is ideal for:

  • Walls
  • Roofs
  • Structural beams and supports
  • Sheds

Corten cladding comes in a wide range of profiles including corrugated, standing seam, and snaplock.

Corrugated steel sheets have been around for a long time but modern corrugated cladding is worlds apart from the early iron sheets that were used in Australia in the 1800’s. Modern Zincalume or Colorbond steel corrugated cladding lasts at least as twice as long as conventional steel—that means your new cladding will give you many years of enjoyment.

Modern corrugated steel cladding is a great way to provide a real point of contrast in your next building project. Corrugated profiles come in a range of sizes now right down to miniature corrugations of 6mm.

This makes it the perfect choice for feature walls in and outside the house or as iconic features for kitchen cupboards or benches or in the bathroom.

Accessorise your home with corrugated steel cladding.
