Also referred to as Atmospheric Corrosion Resistant Steel, this product is seen as an inexpensive and highly effective material to be used in structural applications which are exposed to the atmospheric elements.
The steel oxidises with pollutants in the air forming a thick layer of rust – this formation acts as a protective layer which prevents the steel from corroding. The layer constantly regenerates and forms over time.
Weathering steel is therefore classed as being a ‘self–protecting’ steel. In normal use the material does not need painting or other external treatment any kind.
Weather resistant steel can be used in a wide range of structural applications. It is a commonly used product in bridge construction because of the lack of maintenance costs. It is also popular in modern architecture where the aesthetically pleasing finish is in great demand for sculptural buildings and fascias.
