Basic classification of steel plates

Steel plate is one of the most widely used forms of steel in industry. According to thickness, it can be divided into thin plates, medium thick plates, and extra thick plates: thin plates with a thickness of less than 4 millimeters are commonly used for car bodies and home appliance casings; Medium thick plates with a thickness of 4-60 millimeters are used for bridge and ship manufacturing; Extra thick plates can reach over 60 millimeters and are mainly used in high-rise buildings and large pressure vessels.
According to the production process, steel plates are divided into two types: hot-rolled and cold-rolled. The surface of hot-rolled steel plate is blue or gray black, with high strength and low price; Cold rolled steel plates have a smooth surface and precise dimensions, but the cost is relatively high.
According to the material, it can also be divided into ordinary carbon steel, high-quality carbon steel, and alloy steel. Understanding these basic classifications is the first step in correctly selecting steel plates.
