Fisher Body developed the industry’s first one-piece all-steel roof, called the Turret Top, and introduced it on all GM cars built in the U.S., beginning with the 1935 model year Chevrolet lineup. Previously, car roofs had been built around a wooden frame covered with canvas, limiting both the vehicle’s structural integrity and its design potential.
