Corrosion Resistant Plates

Corrosion Resistant Plates

Corten steel also known as Cor-Ten is kind of weather resistant steel which could more precisely be termed as atmospheric corrosion resistant steel. Our company supplies an assortment of steel plates, which are accessible in different specifications as per the requirement of our customers. Obtained from reliable vendors, our assortment of these plates is available at a reasonable price. When utilized uncovered, exhibits increased resistance to atmospheric corrosion in comparison to unalloyed steels.

Corten B Steel Plates are corrosion resistant and need no maintenance. The plates are developed using weathering steel and a protecting layer is them on the steel surface when used in hazardous weather conditions. These steel plates are used in welded bridges, high buildings and shipping container, and other outside steel structures.

JIS G 3125:2004: eastern grade for climate resistant metallic plates: superior atmospheric corrosion resisting rolled steels this widespread specifies the rolled steel having excessive atmospheric corrosion resistance, for use for vehicle, constructing, metallic tower and other shape.

IRSM 41-97 corrosion resistance steel Indian grade for weather resistant metallic plates: IRSM 41-97 general of Indian railways especially formed for wagon frame because of it high resistance to corrosion, main wagon builder being rail train manufacturing facility.
