EN 10025-5 S355J2W Steel Plate Weather Resistant Steel Sheet

S355J2W steel plate is a copper-chromium alloyed structural steel that exhibits superior atmospheric corrosion resistance compared to conventional carbon steels. The unique chemical composition of this alloy facilitates the rapid formation of a stable, self-protecting oxide layer when exposed to weather conditions. This adherent rust patina effectively shields the base material from further environmental degradation.

Description

EN 10025-5 S355J2W steel is classified as Corten steel or weathering steel.

Corten steel is a high-strength weathering steel known for its exceptional durability. The term "CorTen" is a registered trademark of U.S. Steel, referring to their proprietary weathering steel alloy.

This type of steel was specifically engineered to minimize or eliminate the need for protective coatings, primers, or paints to prevent rust. When exposed to outdoor conditions, Corten steel naturally develops a protective rust patina on its surface, which acts as a barrier against further corrosion. Due to this self-protecting characteristic, it is commonly referred to as weathering steel.
