When I think of a steel building, I think of storage buildings or maybe a detached garage for an RV or something like that.  However, I was looking through a site and saw steel school buildings.  Each classroom is a separate building, and they look more like portable buildings all lined up in a row touching each other.  My first thought was what is so good about that, but then I read more information.   These buildings are designed by the best engineers in the U.S., are fire resistant, and are built to withstand the harshest weather conditions which includes tornadoes, hurricanes, and earthquakes.   Sounds like they would be good for parts of the country which are in “tornado alley.”
