-----Rust-proofing Steel
Q. I regularly use 1/4 inch thick steel plate cut @ 20 inch diameter and have it galvanized to prevent steel from rusting as these are installed underground. Are there ways other than galvanizing to prevent rusting?
Thanks,

A. There are a multitude of ways to prevent rust besides galvanizing. There are other hot-dip processes, there is electroplating, there is powder coating, electrocoating, PVD, CVD, and more. You just have to know what your requirements are and take a look at different things to see if there is something better. The closest things I know to galvanizing would be zinc electroplating and Galfan. You can get more info on Galfan at www.galfan.org.

A. Yes you can get more (*cough) info (*cough) there.

But when the university remains central to the marketing of commercial products, with a compelling vested interest towards exaggerating their advantages and understating their weaknesses, the credibility of the whole university nosedives like any other infomercial producer in my opinion. You followin' me there, cameraman?

It seems that Galfan is one of many useful modifications of the hot-dip galvanizing process, with advantages over straight zinc in some instances.
