[0002] Steel structures are made of steel and are one of the main types of building structures. Due to their inherent advantages, such as light weight and high strength, steel structures have been widely used in the construction of large factories, stadiums, and high-rise buildings. To ensure that steel structures have good corrosion resistance, they must be painted before they are put into use.

[0003] When painting steel structures, the traditional method mostly uses manual handheld spray guns for spraying, which has many disadvantages.
