As a leading manufacturer and supplier based right here in Naypyidaw, Naing Steel takes pride in providing robust and reliable materials for Myanmar’s growing infrastructure. We specialize in S355jo steel sheets and plates, a product chosen for its exceptional strength and resilience. Our commitment is to deliver high-quality steel that forms the dependable backbone of your most important projects, ensuring they are built to last with materials you can trust from a local partner you can count on.
The S355jo grade is a fine-tuned alloy primarily composed of iron, carbon, manganese, and silicon, with key additions like aluminum that enhance its ability to withstand impact, especially in colder conditions. This specific composition grants it impressive mechanical properties, including a minimum yield strength of 355 MPa, which is where it gets its name. It’s this combination of high strength and good toughness that makes it a preferred choice over standard grades, offering a superior balance for demanding structural work.
