Galvanized Welded Steel Pipe

Galvanized welded steel pipe is a kind of carbon steel welded pipe coated with a protective zinc layer through hot-dip galvanizing or electro-galvanizing processes.It is manufactured by forming steel strips or coils into tubular shapes and welding them longitudinally,then treated with zinc coating to enhance corrosion resistance and service life.

Compared with black steel pipes,galvanized pipes effectively prevent rusting in humid,outdoor,or mildly corrosive environments.They feature stable dimensions,smooth surface,good weldability,and high mechanical strength,making them easy to cut,thread,bend,and install on site.

Common applications include water supply pipelines,gas transmission lines,electrical conduit,scaffolding,fencing,greenhouse structures,HVAC systems,and general construction piping.They are widely used in residential construction,municipal engineering,agricultural facilities,and industrial infrastructure.

This product conforms to standards such as ASTM A53,BS 1387,EN 10255,and GB/T 3091.Sizes range from small-diameter thin-wall pipes to medium and large sizes,supporting customized lengths,end treatments,and coating thicknesses to meet different project requirements.
