Strategically located in the dynamic heart of Addis Ababa, Tariku Metals stands as a trusted partner for industries seeking reliability and quality. We pride ourselves on being a leading manufacturer and supplier of high-grade materials, with a special focus on our robust Carbon Steel EN-45 Bars. Our commitment is to fuel Ethiopia’s growing infrastructure and manufacturing sectors by providing products that meet rigorous standards, ensuring your projects are built on a foundation of superior strength and unwavering durability.
The composition of EN-45 steel is carefully balanced, primarily consisting of carbon, manganese, and silicon, which gives it distinct characteristics. This specific blend results in excellent mechanical properties, most notably its high tensile strength and remarkable toughness. A key feature of EN-45 is its superb ability to be heat-treated, allowing it to achieve a hardened surface while maintaining a ductile core, making it exceptionally resistant to wear and fatigue under demanding conditions.

EN-45 Bars and Rods are primarily used in automotive components like springs, shafts, and crankshafts, as well as in engineering tools and machinery parts requiring high strength and wear resistance.
EN-45 Bars and Rods offer excellent tensile strength (700-900 MPa), yield strength (450-600 MPa), and toughness, making them ideal for high-stress applications.
Yes, we offer customized Carbon Steel EN-45 Bars and Rods in various sizes and specifications to meet specific application needs.
The unique strength and resilience of EN-45 bars make them indispensable for a variety of heavy-duty applications. They are most commonly used in the manufacturing of critical automotive parts like leaf springs, coil springs, and other vital components that must absorb significant shock and stress. Beyond vehicles, these bars are essential in construction machinery, agricultural equipment, and a wide range of industrial tools where durability and the ability to withstand repeated high-impact loads are non-negotiable for safety and performance.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
