# Galvanized Steel (Zinc Plated Steel) vs Stainless Steel

Zinc Plating is known for its ability to prevent most corrosion, and it is done by just dipping a metal in hot pool of zinc and letting it cooldown. Meanwhile, stainless steel, an alloy that is capable of resisting corrosion.

• Cheap

• Is not coating (hence, scratching will not expose for corrosion)
• Hardnesss of Material ($$UTS_{Stainless} \approx 860 \frac {N}{mm^2}$$) comparatively to Mild Steel ($$UTS_{Mild Steel} \approx 470 \frac {N}{mm^2}$$)

Other than what is said, in what circumstance would you use stainless steel over galvanized steel?

• Much zinc coating is electroplated . Also , zinc rich primer ( paint) gives about the same protection. The main advantage of zinc is that it is cheap ( compared to SS ). – blacksmith37 Nov 13 '18 at 15:39
• A little bit of nitpicking on terminology, "zinc plating" is likely to be interpreted as electroplating; which isn't quite the same as hot-dip galvanizing. They accomplish a similar task; but electroplating is generally less expensive and less protective; as it's a thinner layer of protection. – JMac Nov 13 '18 at 20:36
