Metal file cabinet material: metal filing cabinet main material for cold-rolled steel. Cold-based hot rolled coil as raw materials for a variety of profiles rolling, cold-rolled steel sheet is cold-rolled steel sheet production, commonly known as the cold plate at room temperature. Cold rolled sheet thickness is generally between 0.1-8.0mm. Features: Because there is no annealing, its high hardness (HRB greater than 90), machining poor performance buy metal file cabinet, only a simple directional bending processing less than 90 degrees (perpendicular to the winding direction ). Because cold rolled coil relatively rigid, not suitable for processing, so under normal circumstances requires the annealed and cold-rolled steel surface smoothing treatment. Cold rolled steel sheet is ordinary carbon steel cold rolled sheet for short, is the ordinary carbon structural steel hot-rolled strip, after further cold rolling steel plate having a thickness of less than 4mm. Since rolling at room temperature, no iron oxide skin, therefore, good cold surface quality, high dimensional accuracy, coupled with annealing treatment, the mechanical properties and process performance are superior to hot-rolled steel sheet, in many areas, especially in appliance manufacturing, has gradually use it to replace the hot-rolled steel sheet. Cold-rolled steel sheet includes a variety of high-quality cold-rolled steel sheet metal file cabinets, the most common is carbon structural steel, especially deep drawing cold rolled steel sheet, the sheet is made of high-quality carbon steel 08Al cold rolling steel plates Surface quality is divided into three groups; Ⅰ, Ⅱ, Ⅲ, respectively, particularly high-level, high-level, high surface finishing, according to drawing level is divided into ZF, HF, F grade (on behalf of Punch drawing the most complex, very complicated, complex parts), according to the plate thickness tolerance, is divided into A, B two precision, widely used in automobile and tractor industries. Xiangyu file cabinets to optimize the office environment, timely and effective information document preservation daily needs, let the office more organized and secure, safe, efficient, easy work of humanistic philosophy metal filing cabinet prices, but generally with file cabinets Security lock metal filing cabinet manufacturers, strong security features make the office more security. File cabinet with high hardness quality aluminum and metal surface treatment, more effective play crash, anti-wear features, embedded landslide track drawer, so smooth when the office more sense.
