Q235B welded pipe hot-dip galvanized with threaded or plain ends for plumbing, 导管, fencing and structural use.
Hot-dip galvanized steel pipe is made from Q235B electric resistance welded pipe and coated by hot-dip galvanizing. The zinc layer protects both the outside surface and the pipe bore, giving long service in water, conduit and outdoor applications. Threaded and coupled ends are available for quick, leak-free joints.
