The metal filing cabinet, an essential component of office organization, is primarily constructed from steel plates of varying thicknesses, commonly ranging from 0.5mm to 0.7mm. These thicknesses are chosen not only for their balance between durability and cost but also because they provide sufficient structural integrity to support the weight of numerous documents and files over time. The choice of steel thickness is crucial as it directly impacts the cabinet's longevity, stability, and resistance to deformation under heavy loads. A thicker steel plate generally means a more robust and durable cabinet, capable of withstanding the rigors of daily use in a busy office environment.

However, the quality of the steel used in the construction of these cabinets is equally important and can vary significantly based on the manufacturing process. Hot-rolled steel, while less expensive, often exhibits greater variability in flatness and may have a rougher surface finish compared to cold-rolled steel. Cold-rolled steel, on the other hand, offers superior flatness, a smoother surface, and better dimensional accuracy, which translates into higher load-bearing capacity and improved aesthetic appeal. The differences in material properties between hot-rolled and cold-rolled steel highlight the importance of selecting the appropriate type of steel for specific applications, ensuring that the filing cabinet meets both functional and aesthetic requirements. Therefore, when choosing a metal filing cabinet, it is advisable to consider not only the thickness of the steel but also its quality to ensure optimal performance and longevity.
