In the heart of Kinshasa, Yoane Steel stands as a trusted partner for the region’s builders and fabricators, supplying high-quality materials that fuel progress across the Congo. We specialize in providing robust and reliable S355J2G3 steel sheets and plates, understanding that your projects demand materials that can withstand significant pressure and challenging environments. Our commitment is to deliver not just steel, but the foundational strength for the infrastructure, industry, and ambitions shaping our community, ensuring every piece meets the high standards our clients expect for their most important work.
The S355J2G3 grade is a fine-grained, structural steel known for its excellent balance of strength and formability. Primarily composed of iron with carefully controlled amounts of carbon, manganese, and silicon, it gains its notable toughness through a normalized rolling process. This results in a minimum yield strength of 355 MPa, offering impressive resistance to impact even at lower temperatures. These properties make it a versatile material that is both strong enough for heavy loads and workable enough for various fabrication techniques, from cutting to welding.
