Nestled in the heart of Myanmar’s capital, Naing Steel has built a reputation as a trusted partner for the nation’s growing infrastructure. We take pride in supplying robust materials like our Rockstar 400 Sheet and Plates, engineered to meet the demanding challenges of modern construction. This high-strength steel is a cornerstone for builders and fabricators who refuse to compromise on durability, offering a reliable foundation for projects that shape the skyline and future of Naypyidaw and beyond.
The Rockstar 400 is defined by its exceptional strength and resilience. Its carefully balanced composition ensures consistent performance, boasting a minimum yield strength of 400 MPa, which allows it to withstand significant stress and heavy loads without deforming. This combination of toughness and excellent formability makes it a versatile material that can be cut, welded, and shaped to precise specifications, providing both the muscle and the flexibility needed for critical structural applications.
