What is stronger galvanized or stainless?

Galvanized steel usually stands up well to water exposure—as long as it’s not salt water. Stainless steel, on the other hand, is made by adding chromium to molten steel. Because of its strength and resistance to rust, stainless is the primary metal used in construction.
