Trussed Concrete Steel Company The Trussed Concrete Steel Company was a company founded by Julius Kahn, an engineer and inventor. The company manufactured prefabricated products for reinforced concrete beams and steel forms for building reinforced concrete floors and walls. Kahn invented and patented a unique new technology reinforcement system of construction called the Kahn System that was stronger, more economical, and lighter than the existing old school technology used up to that point to construct buildings. The old method was to use plain straight smooth steel beams or loose rods or stirrups in concrete beams and floors. Kahn's new technology improved system used 45 degree tab flanges or "wings" permanently attached on steel beams that distributed the tension stress for overall improvement in strength of reinforced concrete.
