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.

Vent mode on: Yes you can get more info there. An unbiased comparison, no. It's one thing if a university develops a technology and quietly sells it off. But when they stay central to the marketing, with a compelling vested interest towards exaggerating the advantages of the technology, the credibility of the university nosedives to the credibility level of any other infomercial producer. It is a modern day abomination. Vent mode off.
