For that organic rustic look:
Weathering steel is often generically referred to as “corten” due to the long standing trademark COR-TEN® owned by U.S. Steel. In 1935 this copper steel alloy was developed to eliminate the need for painting large bridge structures. “corten” steel forms a stable rust-like appearance when exposed to the weather.
Until recently “corten” steel was only available as a hot rolled imported product. The quality and source at times being highly variable.
FormBoss™ is privileged to now lead the market in supplying REDCOR® steel as a replacement to imported weathering steels. Proudly made in Australia by BlueScope®, REDCOR® steel is cold rolled and has been specifically developed for Australian harsh conditions. Its cleaner to work with and displays an overall better uniform finish than imported alternatives.
This steel has an increased resistance to corrosion as it forms a protective layer of oxide on its surface which regenerates as required over the steels life.
REDCOR® steel will appear light grey almost polished when first purchased off the shelf. This is simply because it is supplied to us with a thin film of oil on the outer layer, ensuring it doesn’t start rusting on the shelf. It will take anywhere from a few weeks to 4 months to get an even coating of rust.
This is what it looks like before exposure to weather.
REDCOR® steel will appear blotchy for several months before you get a nice even coating of colour. Slight variations in colour will occur, this is due to differences in soil, air conditions and can vastly vary depending on your location. Colours can range from dark orange to a rich dark brown. Over time it will continue to darken until you are left with a stunning, textured brown.
