What is Fe 550 in steel?

Fe 550 is a grade designation for high-strength deformed steel bars used in construction. The "Fe" stands for iron, and "550" denotes the minimum yield strength of the steel in megapascals (MPa). In the case of Fe 550, the steel has a minimum yield strength of 550 MPa. These high-strength steel bars, also known as TMT (thermo-mechanically treated) bars, are commonly used in reinforced concrete structures to enhance the structural integrity and load-bearing capacity. Fe 550 steel is especially suitable for projects that require robust and durable construction materials, such as high-rise buildings, bridges, and other critical infrastructure.
