It is obvious: hot dip galvanization is a process where lage quantities of pieces can be coated with less manpower and with low costs.
Galvanization is one of very few types of coating which was explained in the standards.
And the galvanized steel can be used in designs where there can be erosion to the steel, because of this sturdy coating.

  Galvanization
Galvanization, named after the Italian scientist Luigi Galvani, was originally the administration of electric shocks (in the 19th century also termed Faradism, after Michael Faraday).
Nowadays it typically means hot-dip galvanizing, a chemical process that is used to coat steel or iron with zinc.
Galvanic[?] or sacrificial anode protection uses ingots of zinc electrically bonded to the metal it is to protect where the metals will be subject to an electrolytic solution.

 Back to Basics: Inspecting Welds in Galvanized Steel 2005-10-023
Zinc galvanization, per square foot per year, is the most cost-effective means of corrosion protection in the world today, yet the process of galvanizing steel has been a little understood technology for more than a hundred years.
Galvanization of structural bolts has recently come under scrutiny with the reminder that fully tensioned ASTM structural fasteners should always be qualified after galvanization.
In this case, excess silicon was thought to aid the dissolution of iron from the weld metal during galvanization, resulting in a concentration of iron trapped in the upper surface of the galvanization.

 Galvanization - Wikipedia, the free encyclopedia
Galvanization or galvanisation refers to any of several electrochemical processes named after the Italian scientist Luigi Galvani.
In current use, it typically means hot-dip galvanizing, a chemical process that is used to coat steel or iron with zinc.
Galvanic protection (also known as sacrificial-anode or cathodic protection) can be achieved by connecting zinc both electronically (often by direct bonding to the protected metal) and ionically (by submerging both into the same body of electrolyte, such as a drop of rain).

 Process for adjusting the composition of a zinc alloy used in the galvanization of steel - Patent 4439397
An alloy suitable for use in a process for adjusting the composition of a zinc alloy suitable for the dip galvanization of steel, which alloy consists essentially of from 5,000 to 50,000 ppm by weight of aluminum, and beryllium in a weight ratio to the aluminum of 1/11.5 to 1/24, balance essentially zinc.
The addition of aluminium and magnesium to the galvanisation bath presents special difficulties associated with the low density of these metals, with their high oxidisability, and, to a certain extent, with the fact that these metals are not liquid at the temperature of the molten zinc baths, namely at about 450.degree.
This oxidation, which is slow on a bath not being used, on which a layer of protective oxides forms, is greatly accelerated by the action of the galvanising fluxes (zinc chloride and ammonium chloride) and of the air drawn in during immersion of the articles to be galvanised.

Panels are dipped in the company's galvanization basin for surface sealing before being moved to the rinsing basin.

The two substances—water and aluminum ions—can be re-used separately for the galvanization process: the purified water is used for rinsing once more, and the ions are returned via a pipe to the reaction basin.

 galvanization | English | Dictionary & Translation by Babylon
Galvanization or galvanisation refers to any of several electrochemical processes named after the Italian scientist Luigi Galvani.Originally, galvanization was the administration of electric shocks (in the 19th century also termed Faradism, after Michael Faraday).
This archaic sense is the origin of the meaning of galvanic when meaning 'affected/affecting, as if by a shock of electricity; startled'.
This remains a useful and broadly applied technology, but the term "galvanization" has largely come to be associated with zinc coatings, to the exclusion of other metals.In current use, it typically means hot-dip galvanizing, a chemical process that is used to coat steel or iron with zinc.

 Effect of Temperature and Galvanization on Cold-Formed Steel   (Site not responding. Last check: 2007-11-05)
An experimental program was conducted to study the effect of temperature and galvanization on the mechanical properties of cold-formed steel members typically used in constructing hydroelectric transmission towers.
Coupons cut from both ungalvanized and galvanized members were tested according to ASTM standards at temperatures ranging from -50°C to room temperature.
The test results showed that the processes of hot-dip galvanizing and cold forming, coupled with low temperatures resulted in an increase of the yield and ultimate strengths, as well as in the modulus of elasticity of the materials.

The only thing I wish to point out is that regardless of the effectiveness of priers versus galvanization, the point is that if an OE [Original Equipment] part is galvanized, and we use an aftermarket part that is primed, there is a difference.
I think it is relatively common knowledge that it is much easier to dislodge the primer than it is the galvanization, thus, the protection is not the same in that situation.
If they drill the galvanizing, the underlying metal is exposed to corrosion just as it would be if there was primer which was drilled through.
