Metal filing cabinet is made of steel plate, the general thickness of 0.5MM, 0.6MM, 0.7MM three, it is worth mentioning that the quality of the steel plate is good or bad, with a small steel plant than the small steel plate, hot-rolled The difference between flatness and load bearing capacity is very different from that of cold rolling, and the thickness of the steel plate used is also critical. The thicker the better, of course, the higher the cost, so the vast majority of manufacturers on the false report thickness plus the thickness of the two-sided paint, reported 0.6MM, the actual only 0.4-0.5, and so on.

The main material of the metal filing cabinet is cold-rolled steel. Cold rolling is based on hot-rolled coils as raw materials, under normal temperature for a variety of profile rolling, cold-rolled steel plate is cold rolled steel plate, commonly known as cold plate. The thickness of the cold rolled sheet is generally between 0.1-8.0 mm.

 

Characteristics: Because it has not been annealed, its hardness is very high (HRB is greater than 90), and the machining performance is extremely poor and can only be performed. Single directional bending process (perpendicular to the take-up direction) of less than 90 degrees. Because cold-rolled raw coils are relatively brittle and not very suitable for processing, cold-rolled steel sheets usually require annealing and surface smoothing.
