Serpentines used in water cooling towers are very special productions in terms of both mechanical manufacturing and hot dip galvanizing. The most important final touch of serpentine manufacturing, which requires a lot of detailed expertise, from the type of metal used to its thickness and hardness level, is the coating method. While there is no coating method used in copper serpentines, iron serpentines are coated with hot dip galvanizing coating method, providing high resistance to high water flow and high air flow abrasions.
