The common dimensions of steel plates with thicknesses of 8mm and 12mm are1200 mm× 6000 mm.
Thin steel plate is a steel plate with a thickness of less than or equal to 4mm, medium-thick steel plate is a steel plate with a thickness of between 4 mm and 25 mm, and thick steel plate is a steel plate with a thickness of more than or equal to 25 mm..
Steel plate is a flat steel which is cast, cooled and pressed by molten steel. The steel plate is flat and rectangular, and can be directly rolled or cut from wide steel strip. Steel plates are divided by thickness, and thin steel plates
The width of the plate is 500 ~1500mm; The thickness and width are 600 ~ 3000mm. Plates are divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron plates. According to professional purposes, there are oil drum plates, enamel plates and bulletproof plates. According to the surface coating, there are galvanized sheet, tinned sheet, lead-plated sheet and plastic composite steel sheet.
The steel grade of thick steel plate is basically the same as that of thin steel plate. In all aspects of products, besides bridge steel plate, boiler steel plate, automobile steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, there are also some kinds of steel plates, such as automobile girder steel plate (2.5~ 10 mm thick), patterned steel plate (2.5~8 mm thick), stainless steel plate and heat-resistant steel plate, which intersect with thin plates.
