Steel plate is flat shape, rectangular, directly or by the width of rolling steel strip shear. Steel plate according to the thickness, sheet steel & lt; 4 mm (0.2 mm) the most thin and thick steel plate 4 ~ 60 mm, and 60 ~ 115 mm thick steel plate.
Steel plate by rolling, points of hot rolling and cold rolling. The width of the sheet is 500 ~ 1500 mm.Width is 600 ~ 3000 mm of thick.Divide sheet according to the grade of steel, 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.; According to professional use points, oil drums with boards, enamel using plate, bulletproof plate, etc.; Points according to the surface coatings, galvanized sheet, tin plate, lead plate, plastic plating composite steel plate, etc.
Thick steel plate steel and steel sheet substantially the same.In all aspects, in addition to the bridge plate, boiler plate, automotive steel, pressure vessel steel plate and multilayer high pressure vessel steel and other varieties is thick plate, some varieties of steel such as automobile beam steel plate (2.5 ~ 10 mm thick), decorative pattern plate (2.5 ~ 8 mm thick), stainless steel, heat-resistant steel and other varieties is the same sheet of cross.
