Steel is one of the strongest materials in the world. Despite its strength, steel roofs weigh much less than roods made of asphalt, fiberglass, clay, and concrete.

Steel helped produce the first skyscraper. In 1885, the Home Insurance Building was created. Since then, about 50 percent of the world steel population has been through construction.

Steel is the most recycled material on earth. Steel can be recycled for up to 150 years after it is first produced. When you purchase steel, it is always recycled.
