Corrosion - Wikipedia
Rust is one of the most common causes of bridge accidents. As rust has a much higher volume than the originating mass of iron, its build-up can also cause failure by forcing apart adjacent parts. It was the cause of the collapse of the Mianus River Bridge in 1983, when the bearings rusted internally and pushed one corner of the road slab off its support.
Steel vs Aluminum: Weight, Strength and Cost Differences …
Aluminum vs Steel Cost Cost and price are always an essential factor to consider when making any product. The price of steel and aluminum is continually fluctuating based on global supply and demand, fuel costs and the price and availability of iron and bauxite ore; however steel is generally cheaper (per pound) than aluminum (see galvanized vs stainless for more info on steel).
When should you use galvanized steel or zinc plated …
Well the shiny pretty one is Zinc plating, and the plating is only typically 3 microns thick, the dull one is galvanized and is typically 50 microns thick and therefore provides much more protection. So actually the choice is quite simply, where you only need superficial protection, indoors in a dry climate (and want the aesthetic value) go for zinc plating.

Galvanic Corrosion - an overview | ScienceDirect Topics
Galvanic Corrosion Galvanic corrosion (dissimilar-metal corrosion) is an electrochemical process in which one metal corrodes preferentially, when in electrical contact with a different type of metal, and both metals are immersed in an electrolyte such as water. From: Shreir''s Corrosion, 2010
The result is that one metal will corrode faster than normal (anode), the other will be completely inhibited (hode). Ways to prevent Galvanic corrosion There are different ways to prevent Galvanic corrosion. Heskins focus is on insulation, that is, breaking the
