Based in the vibrant industrial landscape of Addis Ababa, Tariku Metals has built a reputation for supplying high-grade materials that meet the rigorous demands of modern construction and manufacturing. We take pride in being your local, trusted source for Duplex Steel Bars and Rods, offering a product that delivers exceptional strength and durability. Our commitment is to support Ethiopia’s growing infrastructure and industrial projects with reliable, readily available materials that ensure longevity and performance in even the most challenging environments.
These bars and rods are engineered with a unique composition, primarily a balanced mix of chromium, nickel, molybdenum, and nitrogen. This specific formula gives Duplex steel its remarkable mechanical properties, essentially combining the best of both worlds. It offers yield strength that is nearly double that of standard austenitic stainless steels, along with excellent toughness and superior resistance to stress corrosion cracking, making it a robust choice for heavy-duty applications.
