Nestled in the bustling industrial landscape of Addis Ababa, Tariku Metals has built a reputation as a trusted manufacturer and supplier, particularly celebrated for our high-performance Duplex Steel Square Bars. We understand that the strength of the nation’s growing infrastructure and ambitious industrial projects relies on the quality of their core materials, which is why we are committed to providing only the finest and most resilient products to our partners across Ethiopia and beyond.
The exceptional strength of our Duplex Steel Square Bar stems from its unique composition, a balanced blend of chromium, nickel, molybdenum, and nitrogen. This specific formula gives the material a two-phase microstructure that delivers an outstanding combination of high tensile strength and excellent resistance to corrosion, particularly against stress corrosion cracking, making it far more robust than conventional stainless steels.

Duplex Steel Square Bars are generally not ideal for cryogenic applications. Their performance may deteriorate at extremely low temperatures, making materials like austenitic stainless steel more suitable for such conditions.
To choose the right Duplex Steel Square Bar, consider factors such as the required strength, corrosion resistance, temperature conditions, and industry-specific demands. Ensure compatibility with your application’s mechanical and environmental requirements.
Yes, Duplex Steel Square Bars require regular inspection, especially in harsh environments. Checking for signs of corrosion, wear, or structural integrity ensures they continue performing optimally in critical applications.
This remarkable durability makes the Duplex Steel Square Bar an indispensable component in some of the most demanding environments. You will find it forming the structural backbone of chemical processing plants, serving reliably in offshore and marine applications, and within the critical pipelines of oil and gas industries. Its strength and corrosion resistance also make it a perfect choice for architectural accents, bridge constructions, and heavy-duty industrial machinery, wherever longevity and integrity are non-negotiable.
