1. Definition

Cold rolled steel coil/sheet/plate is a thin steel plate processed by cold rolling process, usually with a thickness between 0.2-4.5 mm. It is formed from hot-rolled steel plates after cold processing, which has higher strength and better surface quality.

2.Characteristics

(1) Higher strength: After cold processing, cold rolled steel coil/sheet/plate have fine grains and tight internal structure, so they have high strength and hardness. This makes it widely useful in many fields.

(2) Excellent surface quality: Due to the effects of pressure and friction during cold working, the surface of cold rolled steel coil/sheet/plate is smooth and smooth, without obvious unevenness and wrinkles. At the same time, it also has better surface quality control capabilities and can achieve higher levels of surface quality requirements during the production process.

(3) Diversified uses: cold rolled steel coil/sheet/plate can be further processed according to different needs, such as cutting, bending, stamping, etc. It is widely used in automobile manufacturing, building materials, home appliance manufacturing, machinery manufacturing and other fields.

(4) Good plasticity: cold rolled steel coil/sheet/plate have good plasticity and can change their shape and properties through cold working and heat treatment. This allows it to meet the needs of different uses and has broader market prospects.

(5) Low cost: Compared with hot-rolled steel plates, the production process of cold rolled steel coil/sheet/plate is simpler and consumes less energy, so the cost is also lower. This gives it a competitive advantage in the market and is favored by many businesses and consumers.
