Aluminum or ornamental iron: what is the difference?
The two look similar from the street, but they behave differently.
Aluminum
Aluminum is light, does not rust and comes with a baked-on powder-coat finish. It suits residential yards, pool fences and most HOA lots. It is not as heavy or as strong as steel, but good commercial-grade styles are sturdy enough for everyday use.
Ornamental iron and steel
Steel is heavier and stronger, and it can be welded into custom shapes and large gates. In humid places, though, it will rust where the coating chips, so it needs touch-ups and good finishing. It is a stronger choice for security, driveways and larger gates.
Ask what the finish is, how it is applied and what the manufacturer warranty covers.
