Zinc-Coating

Zinc is a corrosion protection system utilizing the cathodic protection properties of zinc to ductile iron.  In compliance with ISO 8179, zinc is applied to the pipe surface either with an arc-applied, 99.99% pure zinc material or with a zinc-rich paint.  The zinc layer will have a mass of 200 grams/ meter2 and a finished layer of standard shop coat is accordance with AWWA C-151. Minor damage to the zinc does not need repair due to the protective nature of zinc.  Larger areas of damage can easily be repaired with zinc-rich paint.
