Naing Steel stands as a leading manufacturer and supplier in Naypyidaw, dedicated to meeting Myanmar’s growing industrial demands with exceptional quality and reliability. We take pride in producing our robust 400 BHN sheets and plates, materials engineered to withstand the toughest conditions. Our commitment extends beyond mere supply; we partner with our clients, providing solutions that ensure their projects are built on a foundation of strength and durability, supporting the nation’s infrastructure and development goals with trusted, locally-made steel.
These sheets and plates are crafted from a carefully controlled alloy composition, primarily steel with specific micro-alloying elements, which is then subjected to a precise heat-treatment and quenching process. This specialized manufacturing is what gives the material its defining mechanical property: a consistent hardness of 400 Brinell. This high hardness rating directly translates to superior resistance against abrasive wear and impact, ensuring the material maintains its integrity and performs reliably over a long service life in demanding environments.
