It is also used in the manufacturing of air-conditioning equipment, creating metal roofs for houses, and chain link fencing. There are a range of products made of galvanized steel which make use of its ability to resist rusting, withstand the damage done by harsh weather and being stronger and lighter than many other metals. Stainless steel, due to being more expensive and also stronger, is used for big budget projects which require lots of heavy lifting or thick components.
Thus, stainless steel finds use in the building of skyscrapers, bridges, monuments and sculptures, cars, railways, airplanes and many other high-end products. As we can see, the two types of steel are quite different from one another, and each carry their own set of advantages that make them uniquely suited to a diverse range of applications.

Stainless Steel vs. July 20, Galvanized Steel: Dipped for Defense Galvanized steel is created by dipping standard steel into molten zinc by a process called hot dipping. Stainless Steel: Built to Last The main benefit of utilizing stainless steel tools and equipment is the corrosion durability. Strong as Steel In terms of strength, steel that has been galvanized and stainless steel are both strong options. Protection is Worth the Extra Money Corrosion is the burden of any outdoor worksite.

Although I don't know the feasibility of galvanizing stainless steel, lots of parts are made with dissimilar metals as long as the whole surface is coated with the same metal. Many bright decorative things like slot machines are made by brazing steel pieces together then nickel-chrome plating them so the different electrochemical potentials of brass and steel do not cause a galvanic problem.
To clarify a little I am using SS, and this should have enough nickel to allow for galvanizing. Our vendor is having to dip the piece twice. The first coat covers the plain steel and puts a splotchy coat on the stainless.
They let the part cool enough to handle, then dip it back into the zinc. On this second coat, the zinc sticks to the stainless. Are there variables in their tank that I should be asking about?
This doesn't make much sense to me. The hot dip galvanizing may not stick to the stainless steel unless the zinc penetrates the passive oxide film on the SS to form a metallurgical bond. HD galvanizing is typically not a good idea for series SS because the zinc will preferentially penetrate the grain boundaries of the SS. The same problem can occur from welding SS to galvanized steel. If these assemblies are subjected to external forces, the mechanical properties, especially fatigue behavior, may not be what is expected.
If these assemblies are used at elevated temperatures, catastrophic failure from solid or liquid metal embrittlement is possible. Galvanic corrosion should not be problem if the whole assembly is coated. The zinc will be sacrificial for both the stainless and the plain steel. In most environments, galvanic corrosion of steel in contact with stainless is not a big problem, since the stainless surface should be passive and not available to participate in the corrosion process.
The mixed weld area could be different story. To minimize search efforts and to offer multiple viewpoints, we combined previously separate threads onto this page.

What are the best parameters to hot dip galvanize stainless fluxes, temperatures, additives? The exact parameters necessary would depend on the specifics of your parts. Both hot dip galvanisation and thermal diffusion galvanising have powerful applications. In general, galvanised steel is less expensive than stainless steel.
One of the most visually memorable elements of galvanised steel is its variable appearance. Depending on the specifics of the process, galvanised steel can either have a consistent finish or a spangled one, creating a unique appearance.
This is especially important near oceans and other bodies of seawater, as well as areas that face significant exposure to acid rain. Stainless steel is an alloy made of iron, carbon and chromium and occasionally other elements, such as molybdenum, that offer significant corrosion resistance. Instead of being dipped or coated in a protective layer, as galvanised steel is, stainless steel has this defence against damage built into it. There are many different types of stainless steel available, each with different compositions and resultant resistance to various forms of corrosion and damage.
This is useful for industrial applications where stainless steel components may face constant exposures to caustic chemicals or high temperatures, as well as in design work where the alloy could be consistently exposed to salt water or acidic environments.
