BlueScope's range of Cold Rolled Coil products are manufactured to our customer's specified steel grade and dimensions for many applications including bearings, hinges, guard rails, seat parts, bathtubs, stove liners and washers.
Manufactured through our cold rolling mill, which reduces steel thickness to obtain properties such as strength and hardness. Some of the benefits include improved surface quality and shape.
Manufactured by BlueScope, Cold Rolled Coil conforms to relevant Australian Standards, AS/NZS 1595:1998 and AS/NZS 1365:1996 across four product categories, to meet specific manufacturing requirements.
Cold Rolled Coil products are available in a range of carbon and hardness products, structural products, formable products, and vitreous enamelling products with thickness options between 0.4mm to 3.2mm1.
Structural products consist of temper rolled and high strength low alloy steel grades with guaranteed minimum yield strengths ranging from 180MPa to 350MPa. These exhibit good ductility and are suitable for galvanising applications.
| Structural Grades | Surface Finish | Edge Condition | Certification |
|---|---|---|---|
| CA180S-G®, CU200T-G, CA250T-G, CM350-G® |
Cold Rolled, Skin Passed, Oiled/Not Oiled | Trimmed / Untrimmed (Mill Edge) | Chemical Analysis and Mechanical Properties |
Carbon and hardness products consist of Cold Rolled products based on carbon content with guaranteed chemical composition, as well as three Cold Rolled hardness products with guaranteed minimum hardness. The carbon products are typically used in bearings, hardened washers, seals and hinges, and the hardness products are typically used in drum bodies and ends, as well as containers.
| Carbon and Hardness Grades | Surface Finish | Edge Condition | Certification |

Cold Rolled, Skin Passed, Oiled / Not Oiled | Trimmed / Untrimmed (Mill Edge) | Chemical Analysis and Mechanical Properties |
Formable products consist of three grades that include skin passed, deep drawing steels with guaranteed minimum yield strength, and non ageing steels free from stretcher strain. Our formable products have surfaces suitable for general-purpose and exposed applications. Key benefits of BlueScope formable products include excellent weldability, formability, pressing and bending.

- Not all thickness and width combinations are available – refer to BlueScope. The option of oiled or dry surface may be available. Low roughness "Lustre" finish may be available on some products. Trimmed Edge or Mill Edge may be available. A Class thickness, width and flatness are the normal supply condition. B Class thickness, width and flatness may be available by negotiation.
- A larger range of grades are available to match original equipment manufacturer/international parent company original drawings by negotiation.
