The spray paint barrel features a spray painting process on the outer surface of a steel barrel, while the inner surface is treated with galvanizing or PVF coating products. It is made from cold-rolled steel plates processed through stamping, seam welding, and spraying, with thicknesses typically of 1.2mm, 1.0mm, and 0.8mm, ensuring reliable quality. These barrels are widely used in industries such as dyes, pharmaceuticals, spices, food, resins, lubricants, coatings, and chemical metallurgy. The spray paint barrel comes in large, medium, and small types, as well as spray machine barrels, sun barrels, and polishing barrels.
