Product Overview
The Corten Steel A588 Gr.A Coil is a low-alloy high-strength weathering steel coil designed to resist atmospheric corrosion while maintaining exceptional strength and weldability.
As per ASTM A588 / ASME SA588 standards, this material forms a stable oxide layer on its surface when exposed to the atmosphere, eliminating the need for painting and ensuring long-lasting durability with minimal maintenance.
Gnee supplies high-quality ASTM A588 Gr.A Corten Coils suitable for bridges, buildings, facades, railcars, and other outdoor structural applications.
With excellent resistance to harsh weather conditions, these coils are a preferred choice for architects, fabricators, and infrastructure developers worldwide.
Key Features
Superior Corrosion Resistance: Self-weathering oxide layer protects against atmospheric corrosion.
High Strength & Weldability: Suitable for heavy-duty structural applications.
Cost-Effective: Eliminates the need for painting or surface treatment.
Reliable Quality: Supplied with Mill Test Certificates (EN 10204 3.1 / MTC) for full traceability.
Flexible Supply: Available in multiple thicknesses and widths to meet diverse project needs.

What is the difference between ASTM A588 Grade A and B?
Astm a588 gr a sheet material has a slightly different chemical composition than grade b. The latter has higher copper and chromium levels. Due to the compositional difference, grade b shows more resistance to corrosion than gr a.
What is ASTM A588 Grade A equivalent to?
The ASTM A588 grade A plate is equivalent to Corten A steel plate. ASTM A242 plate is equivalent to Corten B. Compared with common low alloy high strength steel such as A572 Grade 50, ASTM A588 and ASTM A242 has advantages of weathering resistant performances.
What is the difference between ASTM A36 and ASTM A588?
ASTM A36: It is widely used in general structural applications such as buildings, bridges, and machinery parts. ASTM A588: It is commonly used for outdoor structures exposed to the elements, including bridges, buildings, transmission towers, and freight cars.
What is the difference between ASTM A606 and A588?
A606-4 is considered weathering steel sheet with thicknesses beginning at 22 Gauge and thicker available up to 3/16". We stock A606-4 in flat sheets, coil, and panels. A588 is available in steel plate and starts at 3/16" thickness and increases up to 5" thickness.
What is the strength of ASTM A588 steel?
ASTM A588 has a 50ksi minimum yield strength and a 70ksi minimum tensile strength.
