Paragon Steel built and delivered the stainless steel ducting that transports 500,000 lbs of exhaust gas per hour to the Georgia Pacific facility adjacent to the THUMS power plant at Pier D in Long Beach for fueling the dryers on the wallboard production line. The duct is nine feet in diameter and stretches more than 900 feet in length. These aerial views are the only way to photograph the project and convey its true scope.
