Which is better colorbond or Zincalume?

How can you tell if something is galvanized?
Using a magnet or gauge will only determine if there is a zinc coating on top of the steel. And as a matter of fact, the gray coating she sees may be just paint. A film of paint would have a thickness to it. The only real way to determine if the coating is hot-dip galvanized would be to run laboratory testing.
What Colour is Galvanised steel?
When the steel is withdrawn from the galvanizing bath, it has a clean, bright, shiny surface. With time, this changes to a dull grey patina as the surface zinc reacts with oxygen, water and carbon dioxide in the atmosphere to form a complex but tough, stable, protective layer which is tightly adherent to the zinc.
What is the best primer for galvanized metal?
If applying to galvanised surfaces that have been prepared with Mordant Solution then prime first with Rust-Oleum 1080 High Build Primer, this will ensure excellent corrosion protection and lasting flexibility.
Can galvanized steel rust?
Yes, galvanized steel resistance to rust corrosion depends largely on the type and thickness of the protective galvanized zinc coating, but the type of corrosive environment is also a critical factor. Factors that rust and corrode galvanized steel: Relative humidity above 60%
