ASTM A588, A709-50W, A572-50, and A709-50 Corten steel angles are high-strength, low-alloy structural steel sections designed for superior performance in corrosive and load-bearing applications. These angles exhibit excellent atmospheric corrosion resistance (2–4 times that of carbon steel), reducing the need for protective coatings in outdoor environments. They are commonly used in bridges, transmission towers, architectural structures, and heavy construction due to their weldability, formability, and long-term durability.
ASTM A588: Weather-resistant steel with enhanced corrosion resistance, ideal for exposed structures.
ASTM A709-50/50W: High-performance steel for bridges (Grade 50W meets weathering requirements).
ASTM A572-50: Economical high-strength low-alloy (HSLA) steel with good weldability.
Corten Steel: Patented weathering steel that forms a stable rust-like protective layer.

Standard Angle Sizes: L2×2×1/4" to L8×8×1" (or metric equivalents)
