Flat Bar

Carbon Steel Flat Bar | Hot Rolled Solid Rectangular Steel

Flat bar, also known as “flat steel” or “flat bar steel,” is a rectangular cross-section steel product with a wide range of applications in construction, engineering, manufacturing, and daily use. With its simple shape, uniform dimensions, and excellent mechanical properties, flat bar has become one of the most versatile materials in the steel industry. Our hot-rolled flat bars are produced in compliance with international standards such as ASTM A36, JIS G3192, ensuring consistent performance and high-quality finishes.

Flat bars are valued for their ease of fabrication, weldability, and ability to be customized into various forms such as cut lengths, drilled parts, or bent components. With superior load-bearing capacity, durability, and corrosion-resistant treatment options (such as galvanizing or coating), our flat bars are suitable for both indoor and outdoor use in demanding environments.
