　　The most basic steel office filing cabinet material is cold-rolled steel.Cold rolled steel sheet is made of hot rolled strip and rolled at room temperature at recrystallization temperature.Cold rolled steel plate is a kind of steel plate produced by middle carbon cold rolling process.Carbon content is generally less than 2.0%, referred to as cold tie board.The thickness and width of cold-rolled sheet depend on the capacity and market demand of each plant.

　　Cold-rolled steel sheet surface cleaning, fine processing, by bending sheet metal, punching and welding inspection qualified products hot water cleaning (skim)/degreasing cleaning, water cleaning, hydrochloric acid filter and water washing, phosphating film surface adjustment/pure water cleaning, hot water washing (skim), degreasing/degreasing, washing, acid washing, cleaning, washing, and surface adjustment.

　　The choice of steel office filing cabinet directly determines the quality stability and appearance of steel office filing cabinet.The choice of a steel office filing cabinet first depends on the thickness of the clothing plate.In the market, according to the thickness of the plate, generally divided into thick plate steel file cabinet and sheet steel file cabinet.At present, common on the market sheet steel office file cabinet steel plate thickness is generally 0.3-0.5 mm, thick plate is generally 0.6-0.8 mm, plus surface spraying finished products, the thickness will increase by 0.1mm-0.2mm.

　　The steel office file cabinet of sheet metal is too thin because of the choice of material, the bearing force and durability of the product cannot be guaranteed, this is the result of excessive low price competition in the market and the continuous reduction of product prices, strictly speaking, cannot meet the actual demand of users for the steel office file cabinet.Therefore, only before spraying choose the thickness of 0.6 mm above the bare plate, is to ensure that the steel office filing cabinet perennial use of the foundation.

　　The thickness of the sheets, however, does not ultimately determine the quality of the steel office filing cabinets; more importantly, it depends on the choice of material.Steel plate of the same thickness in different situations, the quality is completely different, the steel office filing cabinet is better selected materials, carbon content is moderate, more suitable for bending, stamping and assembly, the finished product effect is smoother, beautiful, better stability.The cold-rolled steel plate has the advantages of moderate hardness, small bending error, smooth surface and no waviness.

　　Surface painting and workmanship are also important factors in the choice of steel office filing cabinets, do not be confused by the low price, not to mention the myth of steel plate thickness.More should observe and pay attention to whether the steel plate is the national standard steel plate, the quality of the steel plate, the manufacturer and the subsequent production process.
