A588 Grade A steel plate,A588 Grade b steel plate,Corten A steel plate

High-strength atmospheric weathering steel plate engineered for long-term outdoor performance. A588 (sometimes referenced as Corten A in commercial naming) is a low-alloy structural plate with improved resistance to atmospheric corrosion compared with ordinary carbon steel. Available in Grade A and Grade B, these plates are specified where reduced maintenance and extended service life in exposed environments are required.

Key attributes:

• Improved atmospheric corrosion resistance: forms a protective oxide patina that slows further corrosion and reduces the need for frequent painting or coatings in many applications.
• High structural strength: suitable for load-bearing and welded or bolted structural members. Grade B provides higher minimum strength than Grade A, allowing selection based on design requirements.
• Fabrication-friendly: designed for standard plate fabrication processes including cutting, welding and forming when proper procedures are followed.

Common applications:

• Bridge components and structural members exposed to weather
• Shipping containers, outdoor storage tanks and railway cars
• Architectural cladding, façades and landscaping structures
• Heavy equipment and infrastructure in corrosive outdoor environments

Availability and commercial notes:

• Supplied as steel plate in various thicknesses and plate sizes (confirm availability and dimensional tolerances with supplier).
• Selection between Grade A and Grade B should be made based on structural strength requirements and applicable project specifications.
• For bidding and design, request mill test certificates and inspection reports to confirm chemical and mechanical properties and traceability.

If you need material certificates, dimensional options, surface finish or cutting/processing services, request those details from the supplier to ensure the plate meets project specifications.
