Our carbon steel coils are produced under strict quality control systems, ensuring consistent thickness, excellent mechanical properties, and optimal surface finishes.

Available in a range of grades, dimensions, and finishes, our carbon steel coils meet global standards and serve industries like construction, automotive, manufacturing, oil & gas, and heavy machinery fabrication.

What are Carbon Steel Coils?

Carbon Steel Coils are long, continuous strips of carbon steel rolled into coil form for easy handling, transportation, and further processing. Depending on the rolling process, coils are categorised as hot-rolled (HR) or cold-rolled (CR).

Hot-rolled carbon steel coils offer superior strength and are ideal for structural applications, while cold-rolled coils feature a smoother surface finish and are used for precision manufacturing where aesthetics and tight tolerances are critical.

Due to their flexibility, carbon steel coils are widely used to manufacture sheets, strips, pipes, tubes, and various fabricated components.

Frequently Asked Questions

Explore our FAQs for insights on materials, customization, and delivery.

What is the difference between hot-rolled and cold-rolled carbon steel coils?

Hot-rolled coils are produced at high temperatures and are ideal for structural applications. Cold-rolled coils are further processed for a smooth surface and tight tolerances, ideal for precision manufacturing and visible parts.

Can carbon steel coils be galvanised?

Yes. Carbon steel coils can be zinc-coated (galvanised) to improve corrosion resistance, particularly for outdoor and marine applications.

Do you offer slitting and custom widths for coils?

Absolutely. Stellanox Steel provides precision coil slitting and cut-to-width services to match project requirements.

Are carbon steel coils suitable for load-bearing applications?

Yes, especially hot-rolled coils like A36 or S275JR, which offer excellent load-bearing strength.
