Elcardo pre-galvanized product range goes as Tubes –Square Tubes, Rectangular Tubes, and Round Tubes. The market refers to Square and Rectangular Tubes collectively as Box Bars. On the Round Tube, however, the customer may get cheated into thinking they are Round Pipes. Pipes are not made from Pre-galvanized sheets and whoever claims as such are cheating on you. Tubes are differently manufactured and differently used and, accordingly, differently priced as well
