Fe 500D Corrosion Resistant Steel TMT

AF Star Corrosion Resistant Steel (CRS) Bars are TMT rebars that offer the perfect combination of strength and longevity, ensuring that your structures stand the test of time. CRS TMT bars are treated with a special coating to prevent rusting.

The coating is typically made of materials such as zinc, or polymer, which provide a protective layer on the surface of the steel bars. This layer helps prevent the steel from coming into contact with moisture and other corrosive elements that can cause rust and deterioration over time.

Steel has a distinct advantage in construction due to its vast range of strength compared to other metals. Our company offers Fe500D CRS (Corrosion Resistant Steel) TMT Rebars which is considered the strongest TMT grade currently available. This particular grade of steel is produced using advanced technology that provides two desirable properties simultaneously - high strength and high ductility, making it ideal for structures that can withstand earthquakes. To achieve greater strength specific alloying elements are added while keeping the carbon percentage low, thus ensuring that the steel retains its adequate ductility.

Fe 500D CRS TMT rebars are commonly used in coastal regions or areas with high humidity, coastal regions, and environments where harsh chemicals are present. They are suitable for use in concrete structures that are exposed to corrosive chemicals, such as those used in wastewater treatment plants or industrial facilities.

AF Star Fe500D CRS TMT rebars are the best choice for construction projects, including bridges, high-rise buildings, industrial facilities, and residential buildings.

The use of AF Star Fe 500D CRS TMT rebars can increase the lifespan of concrete structures and reduce maintenance costs over time, making them a popular choice for construction projects. Their high tensile strength ensures that they can withstand heavy loads and seismic forces, making them ideal for use in high-rise buildings, bridges, and other critical infrastructure projects.

One of the key features of AF Star Fe 500D CRS TMT rebars is their unique rib pattern which is designed to improve the bonding between the steel and the surrounding concrete. This improves the overall structural integrity of the concrete, making it more resistant to cracking and other forms of damage.

AF Star CRS TMT bars are manufactured to strict standards, which ensures that each bar has uniform dimensions and properties.


AF Star CRS TMT bars are manufactured using eco-friendly processes that minimize waste and reduce environmental impact.

As Per BIS….

To enhance the properties of low alloy steel, alloying elements such as Cr, Cu, Ni, Mo, and P can be added, but the combined content of these elements must be at least 0.40 per cent. If phosphorus is used, it should not exceed 0.12 per cent, and if it does, the carbon should be limited to a maximum of 0.15 per cent. Weathering steels conforming to IS 11587 may lead to pitting and crevice corrosion when embedded in chloride-contaminated concrete.
