Steel is just about the most recyclable building material on earth. You could be well reading this in an office building built with steel originally smelted from iron in Julius Caesars day.
So it makes good green sense to build eco prefab houses with steel…
Steel does not spread fire. Building with steel allows for a lighter load, so it does not require a huge concrete foundation. Making concrete is one of the most carbon intensive building industries there are, producing the heaviest carbon footprint.
