Steel plates are divided into hot rolling and cold rolling according to rolling.
The width of the thin plate is 500~1500 mm; the width of the thick plate is 600~3000 mm. Sheets are divided into 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 sheets, etc.; According to professional use, there are boards for oil drums, boards for enamel, boards for bulletproof, etc.; According to the surface coating, there are galvanized sheets, tinned sheets, lead-plated sheets, plastic composite steel sheets, etc.
The steel grades of thick steel plates are generally the same as those of thin steel plates. In addition to bridge steel plates, boiler steel plates, automobile manufacturing steel plates, pressure vessel steel plates, and multi-layer high-pressure vessel steel plates, which are purely thick plates, some types of steel plates such as automobile 8 mm), stainless steel plate, heat-resistant steel plate and other varieties are intersected with the thin plate.
