FAQs
ARS Fe 550D is a high-strength Fe550D grade TMT reinforcement bar manufactured in accordance with IS 1786 standards. It is engineered to provide superior strength, ductility, and durability for residential, commercial, industrial, and infrastructure construction.
The primary difference is yield strength. Fe550D offers a minimum yield strength of 550 MPa, while Fe500D provides 500 MPa. With higher strength and excellent ductility, Fe550D is preferred for projects that require enhanced structural performance and efficient steel utilisation.
ARS Fe 550D TMT Bars are suitable for reinforced concrete construction, including residential homes, apartments, commercial buildings, industrial structures, bridges, public infrastructure, foundations, columns, beams, and slabs.
Ductility allows reinforcement steel to deform under heavy loads without sudden failure. This helps reinforced concrete structures absorb stress more effectively, making them safer during earthquakes, dynamic loading, and other demanding service conditions.
ARS Fe 550D TMT Bars are manufactured in compliance with IS 1786 and are backed by BIS Certification, SGS Testing, SERC Certification, and stringent in-house quality control to ensure consistent product quality and performance.
Yes. ARS Fe 550D combines high strength with excellent ductility, helping reinforced concrete structures withstand seismic forces more effectively. Its mechanical properties make it a dependable choice for earthquake-resistant construction when used as part of a properly engineered structural design.
ARS Fe 550D is designed for general reinforced concrete construction, offering high strength and ductility. ARS CRS Fe 550D provides these benefits along with enhanced corrosion resistance, making it suitable for structures exposed to moisture, coastal environments, and high-salinity conditions.
