As a leading manufacturer and supplier based in Naypyidaw, Naing Steel is proud to be at the forefront of Myanmar’s construction industry by providing high-strength, hot-rolled S500MC sheets and plates. We understand the demands of modern infrastructure, which is why our commitment lies in delivering materials that combine exceptional durability with the versatility needed for ambitious projects. Our focus is on empowering builders and engineers across the nation with reliable, locally-produced steel that meets rigorous international standards for performance and quality.
The S500MC grade is a thermomechanically rolled steel known for its excellent strength-to-weight ratio. Its specific chemical composition, including micro-alloying elements, allows it to achieve a minimum yield strength of 500 MPa without the need for heat treatment. This process gives the material superior formability and weldability compared to conventional steels of similar strength, making it easier to fabricate into complex shapes while maintaining its structural integrity and performance under stress.
| Grade | C | Si | Mn | P | S | Al (min) | Nb | V | Ti | Mo | B |
| S500MC | 0.12 | 0.50 | 1.70 | 0.025 | 0.015 | 0.015 | 0.09 | 0.20 | 0.15 | – | – |
| Grade | Yield (MPa) | Tensile (MPa) | Elongation | |
| < 3mm | ≥ 3mm | |||
| S500MC | ≥ 500MPa | 550-700MPa | ≥ 12% | ≥ 14% |
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
These sheets and plates are ideally suited for a wide array of demanding applications, particularly where reducing weight without sacrificing strength is a priority. You will commonly find S500MC used in the structural components of heavy-duty vehicles, trailers, and industrial machinery. In construction, it’s excellent for warehouse purlins, support beams, and other critical elements. Its excellent welding properties also make it a preferred choice for fabricators working on everything from large-scale agricultural equipment to essential components for bridges and other vital infrastructure projects.
