Desta Steel is a trusted manufacturer and supplier of high-quality Weathering Steel Sheets and Plates in Addis Ababa, Ethiopia. Renowned for its superior durability and resistance to atmospheric corrosion, our weathering steel performs efficiently in harsh outdoor conditions. These sheets and plates develop an oxide layer that protects them from the environment and minimizes the need for painting to give them an extra-long life. Available in various thicknesses and dimensions, these weathering steels from Desta Steel are perfect for construction, architectural, and industrial applications. We ensure that every product demonstrates exceptional performance, structural strength, and sustainability through precision engineering and adherence to international quality standards.
The chemical composition of the Weathering Steel Sheets and Plates is essentially iron, with additions of copper, chromium, nickel, and phosphorus. These elements favor the formation of a stable rust-like patina acting as a protective barrier against further corrosion. The tensile strength ranges from 485–620 MPa, and yield strength lies between 345–450 MPa, hence offering toughness and weldability. Due to an excellent atmospheric corrosion resistance and a high level of structural integrity, weathering steel extends service life and reduces maintenance costs in outdoor and structural use.
