Carbon Steel · Alloy Steel · Stainless Steel | Supplier & Exporter
Inox Steel India is a reliable manufacturer, supplier, and exporter of hot rolled flat bars in India, offering a wide range of carbon steel, alloy steel, and stainless steel hot rolled flat bars for structural and fabrication applications.
Our hot rolled flat bars are manufactured through a controlled hot rolling process, where steel billets are rolled at high temperatures above recrystallization. This process ensures excellent formability, consistent thickness, and strong mechanical properties, making hot rolled flat bars ideal for heavy-duty fabrication, construction, and engineering works.
Buyers searching for hot rolled flat bars, steel flat bar price, mild steel flat bar prices, or hot rolled flat bar suppliers in India trust Inox Steel India for ready stock availability, competitive pricing, and dependable supply from Mumbai.
Hot rolled flat bars are rectangular steel bars produced by rolling steel at elevated temperatures, typically above 1,000°C. During this process, steel is shaped easily, resulting in a rough, scaled surface finish commonly referred to as mill scale.
Compared to cold drawn or bright flat bars, hot rolled flat bars offer:
This makes them a preferred choice where precision surface finish is not critical, but strength and economy are essential.
Hot rolled flat bars are especially favored in projects requiring large volumes, heavy sections, and fast fabrication timelines.
In India, hot rolled flat bars see high demand across Mumbai, Navi Mumbai, Pune, Ahmedabad, Delhi NCR, and Chennai, driven by infrastructure development, fabrication units, and EPC contractors.
Internationally, hot rolled flat bars are widely exported to GCC countries, Africa, and Southeast Asia, where robust structural steel products are required for construction, industrial plants, and utility projects.
With dispatch from JNPT (Mumbai), Mundra, and Hazira ports, Inox Steel India ensures timely delivery and consistent supply for domestic and export projects.
