The Press Brake Tub Girder is a steel box section that is fabricated by a single steel plate intended for spans 120 feet long or less. The PBTG greatly reduces fabrication cost and time, eliminates fatigue critical weld inspection and, with the incorporation of a galvanized coating, extends the service life of this girder out to 100 years.
