In the heart of Kinshasa, Yoane Steel stands as a trusted partner for industry, bringing precision and reliability to the forefront. We specialize in the supply of EN10305-2 and EN10305-3 ERW tubing, materials engineered for exacting standards. Our commitment is to provide businesses across Congo with high-quality steel tubing solutions that form the backbone of durable and efficient projects, ensuring that every component we deliver meets the rigorous demands of modern engineering and construction.
Fundamentally, these ERW tubes are crafted from fine-grained steel, offering a consistent and smooth surface finish. They are defined by their precise dimensional tolerances and excellent mechanical properties, including consistent yield strength and good weldability. This makes them exceptionally reliable for structural and mechanical applications where predictability and uniformity are not just beneficial, but absolutely essential for safety and performance.
