The galvanized straight-head spray gun barrel is made of high-strength alloy steel and is hot-dip galvanized to form a uniform zinc layer on the surface. Galvanizing can not only effectively prevent steel from rusting and improve corrosion resistance, but also enhance the hardness and wear resistance of the barrel surface. The straight-head design makes the spray gun barrel easier to operate, especially suitable for applications that require high-precision spraying. The straight-head design can minimize the flow resistance of the liquid during the spraying process and improve the efficiency and consistency of the spraying. The internal flow channel of the barrel has been precisely designed, and the fluid flow is smoother, which can ensure uniform and unblocked spray and reduce the frequency of cleaning and maintenance. This galvanized straight-head spray gun barrel is highly compatible and can be matched with mainstream brands of spray equipment on the market. Whether it is a low-pressure spray system or a high-pressure spray equipment, it can be connected through a simple adapter to ensure the efficient operation of the equipment.
