The steel plate is a flat steel that is cast with molten steel and pressed after cooling.
It is flat, rectangular and can be directly rolled or cut from wide steel strips.
The steel plate is divided according to the thickness, the thin steel plate is less than 4 mm (the thinnest is 0.2 mm), the medium-thick steel plate is 4-60 mm, and the extra-thick steel plate is 60-115 mm.
Steel sheets are divided into hot-rolled and cold-rolled according to rolling.
The width of the thin plate is 500~1500 mm; the width of the thick sheet is 600~3000 mm. Sheets 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 sheet, etc.; Enamel plate, bulletproof plate, etc. According to the surface coating, there are galvanized sheet, tin-plated sheet, lead-plated sheet, plastic composite steel plate, etc.
The steel grade of the thick steel plate is generally the same as that of the thin steel plate. In terms of products, in addition to bridge steel plates, boiler steel plates, automobile steel plates, pressure vessel steel plates and multi-layer high-pressure vessel steel plates, which are pure thick plates, some varieties of steel plates such as automobile girder steel plates (2.5~10 mm thick), patterned steel plates, etc. Steel plates (2.5-8 mm thick), stainless steel plates, heat-resistant steel plates and other varieties are intersected with thin plates.
In addition, the steel plate also has a material, not all steel plates are the same, the materials are different, and the places where the steel plates are used are also different.
Steel plates are widely used in the manufacture of various stamping parts, architectural and engineering structures and some less important machine structures and parts.
Components, welded structures and other structural parts that require high strength are subjected to impact at low production temperatures.
Used in buildings, bridges, vehicles, machinery manufacturing and metal structures, etc.
