Galvanized And Stainless Steel Difference

What is the difference in price.

Galvanized and stainless steel difference.

Stainless steel costs four to five times as much as galvanized steel and untreated structural steel. Unlike galvanized steel stainless steel does not rust even when scratched since its protection is actually an integral part of it. Galvanized steel is coated with a thin layer of zinc that helps guard against corrosion. So when there is scratch galvanized steel tend to corrode whereas stainless steel can withstand for a longer period.

In general galvanized steel is more ductile and easier to work than stainless steel. In addition visually stainless steel usually has a more matte surface than galvanizing especially if the stainless steel has not been subjected to a clean mirror finish. This means that whenever it is scratched rusting immediately starts to occur around the scratched area. This means galvanized steel contains regular steel which is covered by zinc while stainless steel is made up of two separate metals mixed thoroughly together.

Galvanized steel is almost the same price as untreated structural steel. Niobium alloys are even more expensive. Galvanized steel without crystallization patterns almost always has a mirror surface with a barely perceptible bluish tint. Galvanized steel has the zinc layer on the surface level but in stainless steel chromium is dispersed inside the steel.

Stainless steel is stronger and more corrosion resistant than galvanized steel.
