What is ASTM A588 steel?

ASTM A588 steel is a high-strength, low-alloy structural steel with a chemical composition that makes it more resistant to meteorological conditions than other carbon steels. That makes it ideal for many outdoor applications. Over time, ASTM A588 steel develops an orange-brown patina, which also means it can remain unpainted.


Producing the features & benefits you want

The enhanced resistance to weather and other atmospheric corrosion allows ATSM A588 steel to be used unpainted in many structural and architectural applications. ASTM A588 steel also performs well in high temperatures and offers an array of benefits over other steels:

  • Powerful: 50ksi minimum yield strength and 70ksi minimum tensile strength
  • Easy to maintain
  • Eliminates painting costs
  • Ideal for welding, riveting or bolting
  • Faster construction times
  • Appealing appearance that blends with the environment and improves with age
  • Resists corrosion better than carbon steels like A36 and A572-50 with or without copper addition
