ASTM A242 Type I Weathering resistant steel plate

ASTM A242 Type I steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.

As the ASTM A242 Type I Weathering resistant steel plate reacts with elements in the atmosphere, the material forms a layer of rust over time which in essence protects the steel from corrosion.
