A steel house, sometimes referred to as a steel-frame house, is a non-traditional home that relies on steel for structural support rather than the more common option of hardwood frames. However, because this kind of steel can be easily customized, it is simple to hide any evidence of it with other materials like wood, concrete, or brick.
