What is the difference between steel and galvanized steel?

Galvanized steel is regular steel sheets that have been coated in zinc to make them corrosion resistant. Regular steel is made of iron which will rust when exposed to moisture, either in the form of rain or ambient humidity.

Does galvanized prevents rust?

Galvanizing protects from rust in a number of ways: It forms a barrier that prevents corrosive substances from reaching the underlying steel or iron. The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.

How do you keep galvanized steel from rusting?

The most important step in preventing corrosion on galvanized steel is keeping it out of environments where it is exposed to substances with a pH below 6 or above 12. One side of this requirement is that it is important to keep galvanized steel out of acid rain.

Why you shouldn't weld galvanized steel?

When galvanized steel is welded, the zinc coating at and around the weld burns away, leaving the area uncoated and unprotected. As a result, the unprotected bare weld could suffer from expedient weld failure.
