Steel filing cabinets use varied plate materials to balance functionality, durability, and cost. Thicker cold-rolled steel plates are used for load-bearing parts (e.g., frames and drawer rails) to ensure structural strength. This combination optimizes performance without material waste.

The choice of plates also relates to usage scenarios. High-contact surfaces like drawer fronts often feature wear-resistant coated steel, while internal components use standard plates to cut costs. Mixing plates also streamlines production—thinner sheets are easier to stamp, while thicker ones suit welding—enhancing manufacturing efficiency.

Lastly, sustainability and cost efficiency drive material choices. This tailored approach balances functionality, affordability, and eco-friendliness.
