Cold galvanizing its various methods.
The cold galvanizing technique is different from all the other galvanization types, since it’s an actual painting process. Through this procedure, a resin-based, zinc enriched varnish is applied. Preparations for optimal cold galvanizing occur with a primary excision of calamine (if there is any), degreasing of the substrate and dusting off the surface.
This process is widespread and effectively used under difficult climatic conditions such as marine and industrial environments. Cold galvanizing, among other galvanization types, does not reach the same levels of protection as hot dip galvanization, but it can be employed as a base to make the most of the metal’s antioxidant properties.Then, a second hand of colored finishing polish gets spread out.
The applying of the protective film occurs by way of high electrolysis and allows some advantages, including the possibility to overlay it on very thin or holed products without deforming or obstructing them.
There are additional cold galvanization types like, for example, electrolytically done cold galvanizing process. As opposed to cold galvanizing, this kind of processing is obtained by immersion in acid or alkaline baths charged by an electrical current.
