Naing Steel is proud to stand as a trusted manufacturer and supplier in Naypyidaw, bringing exceptional materials to the heart of Myanmar’s growing infrastructure. We specialize in providing ASTM A709-50W Corten Steel, a high-strength, weather-resistant steel that is perfectly suited for the demanding projects shaping our nation’s future. This material combines remarkable durability with a distinct, self-protecting aesthetic, making it an intelligent choice for builders and engineers who value both long-term performance and innovative design in their structural applications.
The composition of ASTM A709-50W Corten Steel includes added elements like copper, chromium, and nickel, which work together to form a stable, protective rust patina when exposed to the elements. This unique characteristic is key to its longevity. Mechanically, it offers a minimum yield strength of 50,000 psi, providing excellent load-bearing capacity and toughness. This combination of chemical and mechanical properties ensures the steel can withstand harsh weather conditions while maintaining its structural integrity for decades.
