Situated in the heart of Kinshasa, Yoane Steel has built a strong reputation as a trusted partner for the region’s construction and industrial sectors. We take pride in supplying high-quality materials that meet the specific demands of our environment, and our stock of Corten Steel S355J2W sheet and plate is a perfect example. This isn’t your standard steel; it’s a material designed to endure, offering a unique combination of strength and a remarkable resistance to the elements, making it an intelligent choice for lasting projects across Congo.
The strength of Corten Steel S355J2W comes from its special composition, which includes elements like copper, chromium, and nickel. This alloying gives the steel its signature ability to form a stable, self-protecting rust layer when exposed to weather, eliminating the need for painting. Mechanically, it provides a minimum yield strength of 355 MPa, ensuring excellent load-bearing capacity and toughness, even in colder conditions. This balance of atmospheric resistance and inherent durability is what sets this material apart.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
The uses for this resilient steel are extensive, particularly in our climate. You’ll see it beautifully employed in modern architectural facades, bridges, and outdoor sculptures where its evolving patina is a desired feature. Industrially, it’s ideal for constructing shipping containers, heavy-duty equipment, and structural components for buildings and large-scale infrastructure. By choosing this material, you’re opting for a solution that significantly reduces long-term maintenance, allowing structures to age gracefully while standing strong against the test of time and weather.
