Precision electro-galvanized steel pipe represents a high-grade category of tubing manufactured to tight dimensional tolerances, followed by an electrolytic zinc plating process. Unlike hot-dip galvanizing, this method applies a smooth, uniform, and precisely controlled zinc coating, typically between 8 to 12 μm.The result is a component with excellent corrosion resistance, a superior surface finish, and maintained high precision, making it ideal for applications where both protection and dimensional accuracy are critical.
