Operating from the heart of Addis Ababa, Tariku Metals has established itself as a trusted source for industrial-grade materials. We are proud to supply a premium range of Super Duplex Steel Flat Bars, sourced to meet the rigorous demands of modern engineering. Our commitment is to provide not just a product, but a reliable solution, backed by local expertise and a deep understanding of the specific needs of Ethiopian industries. We are here to support your most challenging projects with materials that are built to last.
The exceptional strength of Super Duplex Steel comes from its carefully balanced composition of chromium, nickel, molybdenum, and nitrogen. This unique blend gives the flat bars a remarkable resistance to pitting and corrosion, far surpassing standard stainless steels. Mechanically, they offer an impressive yield strength that is nearly double that of common austenitic grades. This means you get a material that is incredibly tough and durable, capable of withstanding immense pressure and harsh environmental conditions without compromising its integrity.

Yes, Super Duplex Steel Flat Bars are highly recyclable. Due to their composition and durability, they can be reused in various industries without compromising their properties or performance.
Super Duplex Steel Flat Bars are generally not suitable for cryogenic applications due to their brittleness at extremely low temperatures. Materials like austenitic stainless steel are often preferred for such uses.
Yes, Super Duplex Steel Flat Bars are suitable for underground applications due to their excellent corrosion resistance, especially in harsh, corrosive environments such as soil or groundwater exposure.
The unmatched properties of Super Duplex Steel Flat Bar make it the material of choice for critical applications where failure is not an option. You will find it expertly employed in the demanding environments of offshore oil and gas platforms, within desalination plants processing seawater, and in chemical processing equipment handling aggressive substances. Its strength and corrosion resistance are also invaluable for structural components in coastal architecture, high-stress marine hardware, and pollution control systems, ensuring long-term reliability and safety in the face of extreme challenges.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
