I think you mean anodized, and yes, it is. Galvanized means it's plated with zinc, which won't stick to aluminum.
I wish to use galvanized screws tru aluminum roof OR Stainless screws tru aluminum roof . Any chemical reaction ?
yes
Go with the aluminum if you can afford it.
Aluminum is not generally galvanized as the zinc would not be readily sacrificial for aluminum. There are steel products which derive rust resistance from a coating of aluminum and zinc alloy. Properly maintained, they will be rust free for 20 years or longer.
Aluminum does not rust.
cause the molecules in the metal are squeezed tight together
galvanised steel is a lot more safer....... if u go by the book.... it is upto 10 times stronger than stainless steel in aluminum
Galvanized steel. It lasts longer and is less affected by chemicals and saltwater if you choose to go that route. I do suggest saltwater. It needs for less maintance than a pure chlorine pool.
Some nails are made of copper or brass. Also, some nails are galvanized to protect them from rust. There are also aluminum nails--they're used with vinyl siding and aluminum trim coil.
It really depends on the purpose, Aluminum is lighter (depending on the thickness) and will not rust (Nonferrous). However Galvanised steel is cheaper normally, as it is just a coat of zinc on steel, the only problem is that if it gets scratched enough to take away the zinc coating, then it will corrode just as fast as normal steel. Both have similar enough strength though. It mostly just depends on what you are wanting to do.
The main types are wrough iron, aluminum and steel. For aluminum or steel furniture, look for metal that is stainless, galvanized or powder-coated. Cast iron has been replaced now by wrought iron for patio furniture.
Most shopping carts are made of a combination of metal and plastic. In general, the metal is a combination of galvanized steel or aluminum.
