Weathering steels are used in many countries in an unpainted condition to take architectural advantage of their structural and aesthetic qualities.
BlueScope produces a range of weathering steels which—in non-marine and non-industrial environments—offer enhanced weather resistance when compared to traditional structural steel grades such as 250. These steels are widely recognised for their distinctive ‘patina’ which results from protective surface oxidation and develops during exposure to the atmosphere.
