Do metal beds in a beach house rust?

There is indeed a possibility of rust. Since metal beds are structurely built by metal. It may be a brass, copper, aluminum, wrought iron and many other types of metal. We initially think that metal can be deteriorated by rust. But each type of metal has their own properties. Since air by the beach is quite salty and of different temperature than the breeze we normally feel at the park or other places, it can possibly affect the metal. However, it still depends on the type of metal used for the beds in a beach house. Like for example, if it is made of wrought iron it will rust unless properly maintained.
