Structures built out of still have a lot of advantages over structures
of asphalt, vinyl or good old wood. For starters, steel buildings are
cheaper to construct than concrete or wooden structures. Why? It is
because steel can be prefabricated and the individual parts can be
easily assembled. The structures have all their pressure points and
support points made out of this metal so they are stronger and less
prone to damage. Steel sustains no rotting, termites or mildew caused
to wood by absorption of water. Steel is quite flexible and so it can
withstand minor quakes. Also, they do not combust or are bent or
broken by hurricane force winds.
