Steel is a building material that won't let you down. It's damp resistant and won't be affected by mold. It doesn't shrink or swell. Whatever the weather conditions it's exposed to during the construction process, it still retains its original strength and shape. And even though it's so lightweight, it has a surprisingly load bearing capacity.
