Product Overview

Our Q195 Hot Dip Galvanized Round Pipe, equivalent to EN S195T grade, is low-carbon hot-dip galvanized carbon steel round tube. Manufactured by hot dip galvanizing technology, the zinc coating forms a protective layer to resist rust and corrosion in humid & outdoor environments. Q195 / S195T material features outstanding ductility, easy bending, punching and welding. We supply Q195 galvanized round pipe in DN15-DN600, Sch40 standard wall thickness, standard length 6m /12m or custom cut length 1m-18m. It is widely used for agricultural greenhouse frames, light steel structures, fencing, cable protection conduits and low-load support projects. Pipe end processing options including plain end, bevel end, threaded end are available.
