Overview of S355JOWP+N Plates
S355JOWP+N Plates are a premium variant of weathering structural steel designed for superior resistance to atmospheric corrosion. The ‘+N’ stands for normalized delivery condition, enhancing the material’s toughness and weldability. Supplied under EN 10025-5, these plates develop a protective oxide layer when exposed to the elements, eliminating the need for frequent painting or maintenance.
Triton Alloys Inc. stocks an extensive range of S355JOWP+N weathering steel plates in various sizes and thicknesses, ready for rapid dispatch with custom-cutting and value-added services available.
