Steel plate is divided into hot rolled and cold rolled according to rolling.
The width of the sheet is 500~1500 mm, and the width of the thick plate is 600~3000 mm. Thin 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 sheet, etc., according to professional use, there are oil drum plates, enamel plates, bulletproof plates, etc.; according to the surface coating layer, there are galvanized sheets, tin-plated sheets, lead-plated sheets, plastic composite steel plates, etc.
