CRC (Cold Rolled Coil) refers to steel that has been rolled at room temperature after being hot rolled and pickled. The cold rolling process improves surface finish, increases strength, and tightens dimensional tolerances, making CRC coils ideal for precision applications in automotive, appliance, construction, and electrical industries.

Standard CRC Coil Thickness Ranges

CRC coils are typically produced in a wide range of thicknesses to accommodate various industrial needs. Standard commercial thicknesses include:

• From 0.15 mm to 3.00 mm

• Most common sizes: 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, and 2.0 mm

Heavier CRC is often used for structural components or parts requiring deep drawing. Thinner gauges are favored for electronics, automotive interiors, and high-speed stamping.

The exact thickness available depends on the steel grade, rolling mill capabilities, and customer specifications. At Midwest Steel Supply, we offer custom slitting and shearing services to produce coil widths and thicknesses down to exact tolerances.

Typical Tolerance Levels in CRC Coils

Dimensional tolerances in cold rolled coils are much tighter than hot rolled products, which is why CRC is preferred for precision parts.

• Thickness Tolerance:

  • ±0.02 mm for gauges below 1.0 mm

  • ±0.03 mm for gauges from 1.0 mm to 2.0 mm

  • ±0.05 mm for gauges above 2.0 mm

• Width Tolerance:

  • Standard: ±1.0 mm

  • Precision slitting: ±0.1 mm to ±0.5 mm depending on coil width

• Flatness:

  • Cold rolled coils are known for excellent flatness. Typical flatness deviation is <3 mm per 1 meter.

• Edge Tolerance:

  • Slit edge or mill edge available

  • Deburred or rounded edges offered on request for high-precision uses

Tolerances can vary slightly depending on the steel grade and mill, but buyers should always request a mill test certificate (MTC) for verification. Midwest Steel Supply provides full traceability and documentation on every CRC shipment.

Cold Rolled Steel Coil Exporters – Global Leaders in Precision Steel

With rising global demand for high-quality, high-strength steel, several cold rolled coil exporters have emerged as industry leaders, especially in Asia and Europe. These companies specialize in producing and shipping CRC coils to a wide range of markets, from automotive to electronics.
