Based in the heart of Kinshasa, Yoane Steel has established itself as a trusted partner for industry, providing robust material solutions that meet the demanding needs of the region. We take pride in supplying high-grade HB 400 Sheet and Plates, materials chosen for their exceptional strength and reliability. Our commitment extends beyond simple supply; we aim to be a foundational support for the ambitious projects that are building a stronger future for the Congo, ensuring our clients have access to the very best in structural steel.
The HB 400 classification signifies a specific high-strength, abrasion-resistant steel. Its composition includes carefully balanced alloying elements which give it a Brinell hardness of approximately 400, translating directly into superior resistance to wear and impact. This means the plates can withstand significant force and repeated abrasion without deforming or failing. The resulting mechanical strength makes it significantly more durable than standard structural steels, offering a long service life even under the most challenging conditions.
