Letter 9081
Rust-proofing Steel
+
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,

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.

- But an unbiased comparison, uhh, no.
It's one thing when a university develops a
technology and quietly sells it off. No problem.
-
- But when a university stays central to its
marketing, with a compelling vested interest towards exaggerating
the advantages of the technology and understating its weaknesses,
the credibility of the university nosedives to the credibility
level of any other infomercial producer. It is a modern day
abomination. You followin' me there, camaraman?

- It seems that Galfan is a very useful modification of the
galvanizing process, with corrosion resistance and other
improvements over straight zinc.
