Applications
For optical improvement, repair and protection against corrosion of metallic surfaces.
For touch up on galvanized surfaces damaged due to cutting, drilling and welding. Used on damaged galvanized surfaces, steel structures, cable trays, GI gratings, GI steel pipes & tubes, towers, automobile underbodies and parts, off shore steel structures, power plant, chemical plant, transmission towers, trailers, storage tanks, metal roofs on the underground distribution.
Used on ducting, wire fences, bar gates, road signs, traffic light posts, ramps and various other types of steel construction.
What is zinc galvanizing spray?
Usually Zinc coating is done by dipping the Metal to be protected in the high temperature liquid zinc to make zinc coating on the metal by chemical reaction between metal and zinc. Zinc galvanizing spray is the alternative method of protecting the metal (usually steel) by spraying the atomized molten zinc particles to the metal surface. This method is generally used when hot dip galvanizing is not possible or when large jobs are there where conventional zinc coating methods is difficult to apply. So, Zinc galvanizing spray is more costly compare to the hot dip galvanizing.
Generally galvanized metal surface gets open to the atmosphere due to some reasons like welding, transportation or material handling damages. In such cases it is not possible to do hot dip galvanizing or Zinc galvanizing spray process on the metal. So, in such cases Cold Galvanizing Sprays are used to protect such surfaces for rust.
We will discuss more about Cold Galvanizing Spray or Zinc Metal Sprays in this article.
Why is zinc used in galvanizing?
Zinc is an important chemical element having silver grey colour that sacrifice itself to protect metal object from corrosion. Zinc is generally used to prevent steel structure or object from corrosion and it is applied as a zinc coatings or other forms. In hot dip galvanizing process, Zinc is used as a sacrificing agent to protect the metal(steel) from getting corrosion.
How Does a Zinc Coating Prevent Corrosion?
Zinc Coatings protect steel from corrosion in two ways.
Zinc coating becomes a barrier for the corrosion substance to reach to the base metal under the Zinc coating.
The Layer of Zinc sacrifice itself and gives anodic protection to the surface where the metal(steel) is exposed to the atmosphere due to scratches.
Therefore, Zinc Coating give the base metal a long life and corrosion protection in any atmospheric condition.
