Cabinets - Cold rolling thin steel sheet

Cabinet industry knows that cold rolled steel sheet is one of the indispensable raw materials production quality cabinets, since it is the cabinet industry have to understand the knowledge of cold-rolled steel plate, so in order to facilitate your understanding of the cabinet industry further. Cold-rolled steel sheet is short for carbon structural steel manufacture, its working principle is ordinary carbon structural steel hot-rolled steel belt, after further made generally less than 4 mm thickness of cold rolled steel sheet, which we commonly known as the cold plate. Because of the cold rolled steel sheet does not produce oxidation reaction at room temperature, and surface of cold plate is of good quality and high dimensional accuracy, plus annealing treatment its mechanical properties and the performance is better than that of the hot rolled steel sheet. We usually see cold rolled sheet steel grades have Q275, Q235, Q215 and so on, the Q is what mean? Q is the ordinary carbon steel cabinet yield point ( Limit) The code, 195, 215, 235, 255, 275 - Respectively they yield point ( Limit) Numerical, unit: MPa MPa ( N/mm2) 。
