Smooth pipe surface with consistent zinc layer, no peeling or burrs
Good weldability, convenient for cutting and connection during construction
Multiple diameter & wall thickness options, custom cut length available

Product Overview

Our Q215 Galvanized Round Pipe is hot dip galvanized carbon steel welded pipe. Base material Q215 is low carbon steel grade, featuring excellent bending performance, making it the preferred material for fencing pipes. After hot-dip galvanizing treatment, the pipe gains strong protection against rust and corrosion under outdoor humid environments. This Q215 galvanized round pipe is widely applied in fence frameworks, greenhouse supports, light building structures and simple engineering projects. We provide complete size range, support cut-to-length service, all products pass strict factory inspection and come with mill test certificates.
