For builders and fabricators in Addis Ababa and across Ethiopia, Desta Steel stands as a trusted partner in progress. We are proud to manufacture and supply the robust Rockstar 400 sheets and plates, a product line engineered to meet the rigorous demands of the nation’s growing infrastructure and industrial sectors. Our commitment is to provide not just quality steel, but a foundation for strong, lasting constructions that will shape the skyline and economy of our communities for years to come.
The Rockstar 400 is a high-strength, low-alloy steel known for its exceptional durability. Its carefully balanced composition results in impressive mechanical properties, including a minimum yield strength of 400 megapascals. This means it offers superior resistance to wear, impact, and fatigue compared to milder steels. This toughness makes it an ideal choice for projects where structural integrity and long-term performance are non-negotiable, providing a reliable material that can handle significant stress without compromising its form.
