Carbon steel plate is a flat sheet of steel made by pouring molten steel, cooling and pressing.
The steel plate is divided according to thickness, the steel plate <4 mm (the thinnest 0.2mm), medium thick steel plate 4-60 mm, extra thick steel plate 60-115 mm.
The steel plate is divided into rolling, hot rolling and cold rolling.
The width of the sheet is 500~3000 mm;
The thick width is 600~3000 mm.
There are common steel, high quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet.
According to professional use, there are oil barrel board, enamel board, bulletproof board and so on;
According to the surface coating layer, galvanized sheet, tin plate, lead plate, plastic composite plate.

Carbon steel plate can also be called plain carbon steel or carbon steel, in addition to carbon, it contains a small amount of silicon, mananese, sulfur, phosphorus and other elements, the higher the carbon content, the better the hardness and stength, but the worse the plasticity. 

Cold-rolled steel sheets are thin steel sheets produced through the cold-rolling process, characterized by a smooth surface, precise dimensions, and high strength. They are widely used in industries such as automotive, home appliances, and electronics. Their thickness typically ranges from 0.2 to 4.0 mm. After annealing treatment, they exhibit excellent stamping performance and are suitable for precision stamped parts, housing structures, and other applications. Common grades include SPCC, DC01, and Q235B, which are more refined than hot-rolled steel sheets but come at a higher cost.

The steel plate products into high-strength low-alloy steel Plate, carbon structural steel plate, alloy structural steel plate, boiler and pressure vessel steel plate, bridge steel plate, structural steel plate, shipbuilding and marine oil platform steel plate, pipe steel plate, high strength and high toughness steel plate, mold plate, corrosion-resistant plate, composite plate with 12 major series.
Size range: Plate width 1500-4020mm, thickness 6-700mm, length 3000-18800mm.
Delivery status: According to the requirements of users, according to hot rolling, normalizing, tempering, normalizing plus tempering, quenching and other delivery.
