Steel file cabinets are also called iron cabinets. The main material is cold-rolled steel plates. Cold-rolled steel plates are made of hot-rolled coils and rolled at a temperature below the recrystallization temperature. Cold-rolled steel plates are cold-rolled. The carbon content of the steel plate produced in the process is moderate, and the carbon content is generally less than 2.0%, which is referred to as cold rolled plate. The thickness of cold-rolled sheet is generally between 0.1 and 8.0mm. The thickness and width of cold-rolled sheet are determined according to the equipment capacity of each plant and market demand. The surface of the cold-rolled steel plate is smooth and excellent in processing. It is made of steel filing cabinets through sheet metal, bending, welding, pickling, phosphating, and spraying processes.
Steel filing cabinet material description
The selection of
steel file cabinets directly determines the stability of the quality and appearance of the metal file cabinets. The material selection of steel file cabinets depends on the thickness of the plate. According to the thickness of the plate, it is generally divided into thick plate file cabinets and thin plate file cabinets. The thickness of the common steel plate file cabinets on the market is generally 0.3-0.5MM. The plate is generally 0.6-0.8MM, plus the surface sprayed finished product will increase the thickness of 0.1mm-0.2mm. Due to the thin material selection of thin file cabinets, the load-bearing and durability of the product cannot be guaranteed. This is a product that is constantly lowering prices and reducing materials due to excessive low-price competition in the market. In the strict sense, it cannot satisfy users' requirements for steel file cabinets. Actual demand. Therefore, only the steel file cabinet with a bare board thickness of 0.6mm or more before spraying is the basis to ensure that the file cabinet is used all year round.
However, the thickness of the sheet material does not ultimately determine the quality of the steel filing cabinet. What is more important is the quality of the material selection. The quality of steel plates of the same thickness is completely different when different materials are selected. The file cabinet with good material selection has a moderate carbon content and is more suitable for bending, stamping and assembly. The finished product is more flat, beautiful and stable. The advantages of this cold-rolled steel plate are moderate hardness, which ensures that the bending error is small during production, the surface is smooth, and there is no wavy shape. Well-selected file cabinets, flat panels, small errors, flat and beautiful when viewed from the outside, unlike the heart-rising boards on the market, seen as wavy in the distance, affecting aesthetics, and even directly affecting product stability. The surface of the good file cabinet is smooth and bright in color. The surface layer after spraying is smoother and feels better. It also makes the steel file cabinet look beautiful and stylish in the office. Therefore, the thickness of the sheet is not the only criterion for judging the quality of the metal filing cabinet, but more importantly the quality of the sheet.
Of course, in addition to the material selection of the file cabinet, surface spraying and workmanship are also important factors that determine the quality of the steel file cabinet. It is more necessary to observe and pay attention to whether the steel plate is a national standard plate, the quality of the steel plate, the manufacturer and the subsequent production process.
