The plates used in steel filing cabinets are mainly cold-rolled steel plates. ‌ This type of plate is produced through a cold rolling process and has high strength and corrosion resistance, making it very suitable for making filing cabinets.

Cold-rolled steel plates are made from hot-rolled coils through a cold rolling process. They have a moderate carbon content and a thickness generally between 0.1-8.0 mm. The thickness of cold-rolled steel plates commonly used in steel filing cabinets is 0.6-2.0 mm, and are processed through sheet metal, bending, welding, pickling, phosphating, spraying and other processes. ‌

When choosing a steel filing cabinet, the thickness of the plate is an important consideration. The market is generally divided into thick plate and thin plate filing cabinets according to the thickness of the plate. The steel plate thickness of thick plate filing cabinets is generally 0.6-0.8 mm, while the steel plate thickness of thin plate filing cabinets is generally 0.3-0.5 mm. Since the surface sprayed finished product will increase the thickness by 0.1-0.2 mm, the thin plate filing cabinet cannot guarantee the load-bearing and durability of the product due to its thin material.‌
