Welcome to Tariku Metals, your trusted partner in Addis Ababa for premium industrial materials. We take pride in supplying our local industries with the robust quality of Duplex Steel Hex Bars, offering a reliable solution for demanding applications. Our commitment is to support Ethiopia’s growth by providing materials that combine exceptional strength with superior corrosion resistance, ensuring your projects are built to last and perform under the toughest conditions right here in our community.
The composition of Duplex Steel is a thoughtful balance, primarily chromium and nickel, with additions like molybdenum and nitrogen. This synergy gives the hex bar its notable character: it possesses a strength often double that of standard stainless steels, alongside impressive toughness. Furthermore, it offers outstanding resistance to stress corrosion cracking, making it a remarkably durable choice that stands up to harsh environments where other materials might fail.

Yes, Duplex Steel Hex Bars are fully recyclable. They can be melted down and reused without losing their essential properties, making them an environmentally sustainable option for various applications.
Duplex Steel Hex Bars have inherent corrosion resistance due to their composition. However, in highly aggressive environments, additional coatings or treatments may be necessary to enhance their longevity and performance.
To choose the right Duplex Steel Hex Bar, consider factors such as mechanical strength, corrosion resistance, temperature conditions, and compatibility with your application’s specific industry standards and environmental factors.
The unique strength and corrosion resistance of our Duplex Steel Hex Bar make it ideal for a variety of critical applications. You will find it essential in the construction of chemical processing plants, offshore oil and gas platforms, and desalination units. It is also perfectly suited for architectural components in coastal areas, heavy-duty fasteners, and high-stress parts in the pulp and paper industry, providing long-lasting performance where reliability is absolutely paramount.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
