First Beamless Steel Building
MADE entirely of “dished” plates of steel only 3/16 of an inch thick, this building was put up without any beams or other ordinary type of support. It is called “egg-shell type” construction. Measuring 108 feet in diameter and 28 feet high, the building is fireproof and soundproof and insulated throughout. It was built in Chicago.
