Because steel has the highest strength to weight ratio of any building material, it is by nature a superior construction material. Steel does not rot, warp, split, crack or creep and will not expand or contract with moisture content. A steel framed home will always have straight walls and square corners; therefore, homeowners will be relieved to find no wall cracks. It is known that not only is the steel frame much lighter and more elastic than traditional materials like concrete and masonry, it also absorbs energy better by dissipating the force of seismic activity. A typical steel frame home can have superior characteristics during earthquakes than conventional construction, such statement is backed up by a study by a team of engineers from the University of San Diego in California who constructed a six-storey CFS building and made the above video.
