The term cold galvanizing is more of a marketing term than an actual process. Cold galvanizing is simply painting a piece of steel with zinc-rich paint. There are not tanks or preparation necessary other than the equipment you would need to paint any other material (blasting tools, spray guns or rollers, etc.). Because the coating is simply zinc-rich paint, it will not have the durability of hot-dip galvanizing in terms of abrasion resistance, cathodic protection, and service life (or time to first maintenance). The cathodic protection offered by zinc-rich paint is less than hot-dip galvanizing because there are binders and other elements in the paint which limit connectivity of the zinc particles.
