Located in the heart of Kinshasa, Yoane Steel stands as a trusted partner for the nation’s most ambitious construction and engineering projects. We specialize in supplying high-strength S960QL steel sheets and plates, combining local expertise with global standards to deliver materials that build the future. Our commitment is to provide Congolese industries with the resilient backbone needed for structures and machinery that demand unwavering strength and reliability, ensuring every project is built on a foundation of exceptional quality.
The S960QL grade is defined by its exceptional composition and mechanical properties. It is a quenched and tempered alloy steel, carefully balanced with elements like carbon, manganese, and chromium to achieve its remarkable strength. This treatment process grants it a minimum yield strength of 960 MPa, offering incredible load-bearing capacity without significant weight increase. Furthermore, it maintains excellent toughness even in challenging conditions, making it a superior choice where both strength and durability are non-negotiable.

The incredible strength-to-weight ratio of S960QL makes it invaluable for demanding applications. It is the material of choice for the heavy machinery that powers our mining and construction sectors, used in robust crane booms and excavator arms. Beyond equipment, it is essential for critical structural components like bridges and high-rise buildings, and is increasingly vital in the transportation industry for building lighter, yet stronger, freight vehicles and trailers, ultimately enhancing efficiency and safety across multiple industries.
Yoane Steel is a leading manufacturer, supplier and exporter of high-quality Carbon Steel, Alloy Steel, Mild Steel and Galvanized Steel products. Our extensive product range includes Pipes, Tubes, Flanges, Pipe Fittings, Forged Fittings, Sheets and Plates, catering to various industries in Kinshasa, Congo.
