Worldwide Steel Buildings are designed to stand up to the elements, wind, rain, snow, ice, termites, wood-rot and fire. On the evening of May 4, 2007, Greensburg, Kansas was devastated by an EF5 tornado that traveled rapidly through the area, leveling at least 95 percent of the city. Still standing between two large broken oak trees, was our steel building. Our buildings are manufactured in the heartland of America. Perfect protection for your cars, boats, agricultural equipment and other treasures. We are so positive in the strength of our buildings, we include a 50 year warranty.
