ASTM A588 corten flat bars should be your first perfect choice if you want to buy corten flat bars. ASTM A588 corten flat bars is substantially better than that of carbon structural steels with or without copper addition in most environment. When properly exposed to the atmosphere, ASTM A588 corten flat bars is suitable for many applications in the bare (unpainted) condition.
ASTM A588 standard include ASTM A588 Gr.A, ASTM A588 Gr.B, ASTM A588 Gr.C and ASTM A588 Gr.D. and their chemical compositions are as following:

ASTM A588 corten flat bars mechanical properties:
Tensile, min, 70 ksi
Yield, min, 50 ksi
Elongation, in 8”, 18 min %
Elongation, min % in 2”, 21
ASTM A588 covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in weight or added durability are important.
ASTM A588 corten flat bars are bars with improved atmospheric corrosion resistance that is intended for riveted, bolted, or welded construction. ASTM A588 corten flat bars are available in 1/4", 3/8", 1/2", 5/8", 3/4", 1" in thickness and length is 40’ or 20’ Sections, or we can cut the length as your demand.
