Say I buy a 50 acre island. This island is not big enough for an Airport so instead I build an airport connected to the island out to sea, I want this to be able to take the weight of aircrafts and the metal will obviously be held in place like a long bridge.
I may also want to build more greenland, with tree’s and grass, so I lay some of this metal down, cover a thick layer of compost and plant tree’s and grass seeds.

But what metals strong enough?
The airport will be small, and the shopping centre will be on the acctual land, its just more the runways that will be out at sea. I know the military use boats as run ways for war jets…
