Coils

Coils are continuous rolled strip wound into rolls, supplied hot-rolled or cold-rolled in mill widths or slit narrower. They feed tube mills, stamping lines, roll formers and service centres, and are the most economical form for high-volume flat-product users.

Types of coils

Hot-Rolled CoilsHot-rolled coils (HRC) are produced on a hot-strip mill at high temperature.Cold-Rolled CoilsCold-rolled coils (CRC) are rolled at room temperature from hot-rolled coil for tight thickness, flatness and a smooth surface, then annealed (2B/2D) or bright annealed (BA).Slit CoilsSlit coils (strips) are master coils cut lengthwise into narrow widths on a slitting line to suit tube mills, roll-formers and press lines.

Coils by material

Stainless Steel Coils

Nickel Alloys Coils

Carbon Steel Coils

Non-Ferrous Metals Coils

How they are made

Hot-rolled coil (HRC) comes from the hot-strip mill. Cold-rolled coil (CRC) is further reduced on a cold mill, then annealed and pickled or bright annealed, and skin-passed. Slitting lines cut master coils into narrow strips to the width you order.

Frequently asked questions

What is the difference between HR and CR coil?

Hot-rolled coil is rolled at high temperature, with a scaled or pickled surface and wider tolerances. Cold-rolled coil is reduced at room temperature for tighter thickness, a smoother surface and better flatness.

Which materials are coils available in?

Stainless Steel, Nickel Alloys, Carbon Steel, Non-Ferrous Metals: 37 grades in total, from stock or mill-sourced.

What sizes of coils do you supply?

Thickness about 0.3 – 12 mm; widths from narrow slit strip (about 10 mm) to 1,250 / 1,500 / 2,000 mm; coil ID 508 / 610 mm; coil weights to order.

How are coils tested?

Chemical and mechanical tests; Thickness profile and surface inspection; Hardness and bend tests.
