At Zhonglian Yongsheng, you will always find a wide range of longitudinally welded galvanized steel pipes.
Such pipes are thermally (= hot dip) galvanized. This means that these pipes are immersed, giving them a coarse zinc layer that adheres to the inside and outside of the pipe. In contrast to electrolytically galvanized pipes, all sides are treated here and not just the outside.
A hot-dip galvanized steel pipe is resistant to corrosion and has a robust and industrial appearance due to their coarse finish. The galvanized pipes are therefore sturdier and heavier than aluminium pipes. For that reason, we see that galvanized steel pipes are often used in steel construction, traffic engineering and scaffolding construction.
