In the vibrant industrial landscape of Kinshasa, Yoane Steel has established itself as a trusted partner for quality steel solutions. We take pride in our role as a leading manufacturer and supplier, specializing in the precision and reliability of EN10305-1 and EN10305-4 seamless steel tubing. Our commitment is to provide Congolese industries with products that meet the highest international standards, ensuring your projects are built on a foundation of strength and durability, sourced right here from the heart of Congo.
These specific grades of tubing are defined by their exact composition and mechanical properties. The steel used is finely tuned to offer excellent strength, consistent ductility, and reliable performance under pressure. Adhering strictly to the EN10305-1 standard ensures dimensional precision, while EN10305-4 focuses on the high-quality, homogeneous structure inherent in the seamless manufacturing process, resulting in a tube free from weld seams and uniform in its capabilities from end to end.
