Life cycle cost comparisons
Steel is one of the most versatile materials known to man.
It can be forged, rolled, cast, pressed, welded, cut, drawn,
drilled or bent into almost any shape or size. It can be
made harder, softer, more brittle, more ductile, stronger
or weaker by means of alloying elements or heat treatment.
It is the most widely used metal on our planet and society
is wholly dependent upon it. Our houses, shops, factories,
cars, boats, trains, trucks, bridges and machines all rely
upon it. They can be made without steel but at enormous
cost. Steel is comparatively cheap to manufacture and the
iron ore from which it is extracted is widely available.
However, there is one problem when using steel.
If it is left unprotected in the earth’s atmosphere
it will oxidise and revert, in effect, to iron ore. Steel
needs to be protected from corrosion.
