Welcome to Tariku Metals, your trusted partner in Addis Ababa for high-performance materials. We take pride in supplying a comprehensive range of Duplex Steel Flat Bars, combining local expertise with global quality standards. Our dedication is to support Ethiopia’s growing industrial and construction sectors by providing materials that offer exceptional strength and longevity. We understand the demands of modern projects, and our Duplex Steel Flat Bars are sourced to meet those rigorous challenges, ensuring your work is built on a foundation of reliability and superior performance.
Duplex Steel gets its name from a mixed microstructure of austenite and ferrite, creating a remarkable balance of strength and toughness. This dual nature grants it a high tensile strength and excellent resistance to stress corrosion cracking, a common failure point in many standard stainless steels. It also offers impressive resistance to pitting and crevice corrosion, making it far more durable than conventional grades, especially in challenging environments. This unique combination of mechanical properties makes it an exceptionally robust and cost-effective choice for demanding applications.

To maintain Duplex Steel Flat Bars, regularly clean them to remove debris, inspect for corrosion, and apply protective coatings if necessary. Ensure proper storage to prevent exposure to harsh chemicals or extreme conditions.
Yes, Duplex Steel Flat Bars are suitable for natural gas applications due to their excellent corrosion resistance and strength, making them ideal for pipelines and equipment exposed to natural gas environments.
Duplex Steel Flat Bars are partially magnetic due to their ferritic phase. While not as magnetic as pure ferritic steels, they may exhibit some magnetic properties, especially in certain conditions.
The robust nature of Duplex Steel Flat Bars makes them indispensable across numerous industries. They are a fundamental component in the construction of bridges, chemical plants, and desalination facilities where resistance to corrosive elements is critical. Within Ethiopia’s industrial landscape, these flat bars are ideal for structural frameworks, heavy-duty machinery parts, and processing equipment in the food and pharmaceutical sectors. Their durability also proves invaluable for architectural features, shipbuilding, and offshore oil and gas applications, consistently performing where both high strength and corrosion resistance are non-negotiable.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
