What industries use HR coils?

HR coils are widely used across heavy engineering industries including construction, infrastructure, shipbuilding, oil and gas, power generation, and heavy machinery manufacturing. These sectors rely on HR coils for structural and load-bearing applications.

Why choose HR steel for heavy structures?

HR steel is preferred for heavy structures because it provides high strength, good weldability, and availability in thicker sections. These properties make it ideal for large welded components and structural frameworks.

What is the difference between HR and CR coils?

HR coils are produced through hot rolling and are mainly used for heavy fabrication and structural work. CR coils undergo additional cold rolling processes that provide a smoother surface finish and tighter tolerances, making them suitable for precision and finishing applications.

What grades are used in fabrication?

Common grades used in fabrication include IS 2062 E250 for general structural fabrication and IS 2062 E350 for applications that require higher strength and load-bearing capacity.

Do HR coils have certification requirements?

Yes, HR coils supplied for fabrication and structural applications generally include mill test certificates (MTC) that confirm the material grade, mechanical properties, and compliance with industry standards.
