A588 Grade K Atmospheric Corrosion Steel Plate
A588GrK weathering corten steel Execution standard: ASTM A588/A588M.
A588GrK atmospheric steel Delivery condition: hot rolled, normalised, tempered, normal+tempered, tempered. We can choose different delivery states according to your different needs.
A588GrK corten structural steel is commonly used in welded, riveted and bolted structures, mainly for welded bridges and buildings where weight reduction or extended life is required.
In addition, A588GrK corten sheet has significantly better atmospheric corrosion resistance than carbon structural steel in most environmental conditions, and when fully exposed to the atmosphere, A588GrK corten steel sheet metal is suitable for many applications in its bare (uncoated) state.
