Office filing cabinets are the most common metal filing cabinets in our lives. They have a smooth appearance, are not easily deformed, are durable, and have high strength.

1. In the early stage of the recent development of painting office file cabinets, a large soft brush was used, and the paint was wiped on immediately. There is no such thing as anti-rust treatment and degreasing. Most of the office filing cabinets manufactured by this process will take 2-3 years to paint and all will fall off. Using compressed air as the driving force, the paint is dispersed into fine particles and adhered to the wooden cabinet. This process is still being applied in other industries at this stage, such as car maintenance. In this case, everyone has a purpose to eliminate rust, water stains and oil stains on the surface of the cabinet door. The metal office filing cabinets made by this process are significantly more beautiful than painted ones, and the quality is much better.

In fact, to see which brand of metal office filing cabinet does not fade is to distinguish whether the coating process selected for the office filing cabinet and the quality of the electrostatic powder applied are up to standard. First of all, we have to observe whether the surface coating of the office file cabinet is flat, and there is a sag condition in the wood. Secondly, we can stand on the side of the wooden cabinet and observe whether the cabinet door has turned yellow. The normal color should be white or blue. . If these two index values are up to standard, the wooden cabinet will not fall off after 15-20 years of application.
