Steel plate: It is a flat steel that is poured with molten steel and pressed after cooling.

It is flat, rectangular, and can be directly rolled or cut from wide steel strips.

Steel plates are divided by thickness, thin steel plates <4 mm (the thinnest 0.2 mm), medium-thick steel plates 4-60 mm, and extra-thick steel plates 60-115 mm.

Steel plates are divided into hot rolling and cold rolling according to rolling.

The width of the thin plate is 500~1500mm; the width of the thick is 600~3000mm. Thin plates are classified according to steel types, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel, and industrial pure iron thin plates. According to professional use, there are oil drum plates, Plates for enamel, bullet-proof plates, etc.; according to the surface coating, there are galvanized sheets, tinned sheets, lead-plated sheets, plastic composite steel sheets, etc.
