Hot rolled coil thickness range, cold rolled coil thickness range

‌The thickness of hot-rolled coils usually ranges from 0.3 mm to 25.4 mm, and the specific thickness depends on the application and demand of the product. ‌
Hot-rolled coils of different thickness specifications are suitable for different application scenarios: ‌0.3-3.0 mm‌: Hot-rolled coils of this thickness have good plasticity and processing properties, and are usually used to manufacture cold-rolled plates, cold-rolled strips and other products, and are widely used in automobiles, home appliances and other fields. ‌
‌1.2-6 mm‌: The thickness range of hot-rolled thin plates is generally specified as 1.2 to 6 mm, which is suitable for manufacturing steel pipes, steel plates and other products. It has high strength and toughness and is widely used in construction, bridges, ships and other fields. ‌
‌2.0-12.0 mm‌: Hot-rolled coils of this thickness are suitable for manufacturing steel pipes, steel plates and other products, and can withstand large Load and stress, widely used in construction, bridges, ships and other fields ‌

‌1.2-25.4 mm‌: This thickness of hot-rolled coil has extremely high strength and impact resistance, and is usually used to manufacture heavy machinery, building structures and other products, which need to withstand extremely large loads and stresses. It also plays an important role in high-risk industries such as petroleum and chemical industry ‌‌

The thickness range of cold-rolled coil is usually between 0.2-4mm ‌‌

In addition, the thickness of cold-rolled coil can also reach 0.1-8.0mm or less, but the thickness of cold-rolled steel plates produced by most factories is less than 4.5mm ‌

The reason why the thickness range of cold-rolled coil is narrow is that the cold rolling process needs to be carried out at room temperature, and the steel is thinned through multiple rolling, while improving the surface quality and dimensional accuracy of the steel. The surface quality, appearance and dimensional accuracy of cold-rolled products are better than those of hot-rolled products, and they are often used in applications with higher requirements, such as automobile manufacturing and small household appliances production, etc. ‌
