Naing Steel stands as a trusted manufacturer and supplier in the heart of Naypyidaw, Myanmar, dedicated to producing robust materials for the nation’s growing infrastructure. We take particular pride in our 400 Brinell Hardness Number sheets and plates, a product line engineered for the most demanding environments. These materials are crafted with precision to offer exceptional durability, providing a reliable solution for projects where strength and long-term performance are absolutely critical, supporting the builders and innovators shaping Myanmar’s future.
The exceptional strength of these sheets and plates comes from a carefully balanced composition, typically a low-alloy steel that is heat-treated to achieve its remarkable properties. This specialized process results in a material that consistently meets the 400 BHN standard, translating into superior yield and tensile strength alongside impressive abrasion resistance. This combination means the steel can withstand significant impact and heavy wear, offering a dependable level of mechanical performance that you can count on for challenging applications.
