学算钢结构（Steel structure） Classification of steel plate (including strip steel): 1, according to thickness classification: (1) sheet (2) medium plate (3) thick plate (4) extra heavy plate 2, according to the production method classification: (1) hot-rolled steel plate (2) cold-rolled steel plate 3, according to the surface characteristics of classification: (1) galvanized sheet (galvanized sheet, galvanized sheet), (2) tin plate (3) composite plate (4) color coated steel plate 4, according to the purposes: (1) the bridge plate (2) boiler plate (3) shipbuilding plate (4) armor plate (5) car plate (6) roof plate (7) plate (8) electrical steel (steel sheet) (9) spring plate (10) other Two. Common Japanese brand in steel plate for general and mechanical construction 1, Japanese steel (JIS Series) common structure steel grades mainly consists of three parts: the first part of said material, such as: S (Steel) F (Ferrum) steel said, said iron; second part shape, types, different applications, such as P (PLAte) said the board, T (Tube) said tube, K (Kogu) said the third part digital tools; feature representation, is generally the lowest tensile strength. Such as: SS400 - the first S represents steel (Steel), the second S indicates the structure (Structure), and the 400 is the lower limit tensile strength 400MPA, and the overall tensile strength is 400MPa of the ordinary structural steel. 2, SPHC - the first S for steel Steel abbreviation, P for plate PLate abbreviation, H for heat Heat abbreviation, C for commercial Commercial abbreviation, the overall expression of general use hot-rolled steel plate and steel strip. 3, SPHD - indicating hot rolled steel sheet and strip for stamping. 4, SPHE - for deep drawing hot rolled steel sheet and strip. 5, SPCC - indicating cold rolled carbon steel sheets and strips, equivalent to the Q195-215A brand in china. Third of the letters C are cold Cold abbreviations. To ensure tensile test, SPCCT is added at the end of the grade T. 6, SPCD -
