In the heart of Addis Ababa, Tariku Metals is a trusted partner for industries demanding exceptional strength and resilience. We specialize in providing top-tier Super Duplex Steel bars and rods, materials engineered to thrive where others fail. Our commitment goes beyond supply; we ensure that every length of steel meets the rigorous challenges faced by local and national projects, offering reliability and performance that builders and engineers can count on for their most critical applications.
The exceptional quality of these bars stems from a specific composition rich in chromium, nickel, molybdenum, and nitrogen. This alloy blend gives the steel an outstanding balance of high strength and impressive toughness, far surpassing standard stainless grades. They also possess remarkable resistance to pitting and cracking, even under significant stress, making them a robust choice for demanding structural and mechanical roles.

Super Duplex Steel rods are generally resistant to galvanic corrosion due to their high chromium and molybdenum content. However, they can still be susceptible when coupled with highly dissimilar metals in certain environments.
Yes, Super Duplex Steel bars can be welded using appropriate techniques and filler materials. Careful control of heat input and post-weld heat treatment is essential to avoid degradation of their mechanical properties.
Super Duplex Steel rods are available in various sizes, ranging from small diameters to large rods, typically up to 300mm or more. Finishes can include hot-rolled, cold-drawn, polished, or ground, depending on the application requirements.
The unique properties of our Super Duplex bars make them ideal for challenging environments. You will find them essential in chemical processing plants, offshore oil and gas platforms, and desalination units where corrosion is a constant threat. They are also perfect for structural components in bridges, pressure vessels, and pumps, ensuring long-lasting performance and safety in projects that simply cannot afford to compromise on material integrity.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Tariku Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Addis Ababa, Ethiopia
