How to distinguish the thickness of the cabinet of the filing cabinet
Features: Because it has not been annealed, its hardness is very high (HRB greater than 90), mechanical processing performance is very poor, only a simple directional less than 90 degrees of bending (perpendicular to the coiling direction). Because the cold rolled original roll is more brittle and less suitable for processing, the cold rolled steel sheet is usually subjected to annealing and surface finishing.
Cold-rolled steel plate is a common carbon structural steel cold-rolled plate referred to by the ordinary carbon structural steel hot-rolled strip, after further cold rolling made of less than 4mm thickness of the steel plate. Since the surface of the cold plate is of good quality and high in dimensional accuracy, and its annealing performance, the mechanical properties and process performance are better than those of the hot rolled steel sheet. In many fields, especially in the field, Home appliance manufacturing, has gradually replaced it with hot-rolled thin steel plate.
The main material of the metal file cabinet is cold rolled steel plate. Cold rolling is hot rolled coil as raw material, at room temperature for a variety of profiles rolling, cold rolled steel plate is cold rolled production of steel, commonly known as cold plate. The thickness of the cold rolled sheet is generally between 0.1 and 8.0 mm.
The thicker the better, of course, the higher the cost, so the vast majority of manufacturers on the false thickness of the two sides with the thickness of the paint, reported 0.6MM, the actual only 0.4-0.5, and so on.
Iron cabinet is actually made of steel, the general thickness of 0.5MM, 0.6MM, 0.7MM three, it is worth mentioning that the quality of steel plate is good or bad, with a large steel plant than the small steel plate, heat Rolling and cold rolling on the flatness and load-bearing vary widely, and the thickness of the steel plate is also the key.
