Why hot dip galvanizing?

There are several methods to produce zinc coating. When you compare the characteristics of mechanically plated items - coating thickness, bond strength and integrity - with those that have been hot dip galvanized or even electroplated, there are clear differences.

Mechanical zinc plating is achieved by tumbling small components in a mixture of promoter chemicals, zinc powder and tiny glass beads. On impact, the beads actually hammer the zinc powder into the parts. This process can have severe limitations. Mechanical bonding is intrinsically weaker than chemical or electrical bonding. Complex designs may not be thoroughly coated in every recess; media residue can lodge in these recesses or in the threads of fittings or flanges. Edges, corners and thread coating thicknesses are usually lower at these points due to the peening action of the process.

In contrast, hot dipped galvanizing provides more than 30% more zinc per unit volume than mechanical coating, with a consequent increase in protection. Parts are immersed in a bath of molten zinc, then react metallurgically to produce a coating consisting of a series of zinc-iron alloys and a surface layer of almost pure zinc. This coating is intrinsic to the metal, with a bond several orders of magnitude stronger than the mechanical zinc plating. Immersion ensures that the area of the component is adequately coated; vulnerable edges, corners and threads actually receive a thicker coating than the flat surfaces. Even if the coating is scratched, or removed, the zinc-iron layers provide sacrificial anodic protection. Exposed steel on a hot dipped galvanized part will not rust until the coating is depleted.

The Penalty of Leadership

In every field of human endeavor, he that is first must perpetually live in the white light of publicity. Whether the leadership be vested in a man or in a manufactured product, emulation and envy are ever at work. In art, in literature, in music, in industry, the reward and the punishment are always the same. The reward is widespread recognition; the punishment, fierce denial and detraction. When a man’s work becomes a standard for the whole world, it also becomes a target for the shafts of the envious few. If his work be mediocre, he will be left severely alone – if he achieve a masterpiece, it will set a million tongues a -wagging. Jealousy does not protrude its forked tongue at the artist who produces a commonplace painting. Whatsoever you write, or paint, or play, or sing, or build, no one will strive to surpass or to slander you unless your work be stamped with the seal of genius. Long, long after a great work or a good work has been done, those who are disappointed or envious, continue to cry out that it cannot be done. Spiteful little voices in the domain of art were raised against our own Whistler as a mountebank, long after the big world had acclaimed him its greatest artistic genius. Multitudes flocked to Bayreuth to worship at the musical shrine of Wagner, while the little group of those whom he had dethroned and displaced argued angrily that he was no musician at all. The little world continued to protest that Fulton could never build a steamboat, while the big world flocked to the river banks to see his boat steam by. The leader is assailed because he is a leader, and the effort to equal him is merely added proof of that leadership. Failing to equal or to excel, the follower seeks to depreciate and to destroy – but only confirms once more the superiority of that which he strives to supplant. There is nothing new in this. It is as old as the world and as old as human passions – envy, fear, greed, ambition, and the desire to surpass. And it all avails nothing. If the leader truly leads, he remains – the leader. Master-poet, master-painter, master-workman, each in his turn is assailed, and each holds his laurels through the ages. That which is good or great makes itself known, no matter how loud the clamor of denial. That which deserves to live — lives.
