Strength where strength matters – Iron Bull DTB dump trailer beast models are built to work! The industry best DTB sits atop of a dual layer of 6″ I-beam weighing in at 12 pounds per ft main frame construction. That’s 24 lbs/ft of pure steel putting maximum strength into the most critical part of your trailering system. Ironbull has elevated the dump trailer experience with our redesigned Side Armor system. This upgraded design keeps our 24-inch, 10-gauge original sidewall, featuring an oversized break that prevents bowing, ensuring unmatched side rigidity. The enhanced Side Armor introduces a fully enclosed top rail made of 11-gauge steel to safeguard against potential damage during side loading. Corner reinforcements have been strengthened, offering additional welding area to reinforce the dump box. With this advanced Side Armor system, every Ironbull dump trailer boasts an industry-leading dump box, allowing you to concentrate on your tasks with confidence.
