The Alumax features a heavy-duty 8-inch extruded top rail that resists bowing from heavy internal loads. The heavy-duty bottom rail, which includes an inside radius for faster and cleaner dumping, ties the deck, sides, crossmembers, vertical posts and outside dirt shedders together providing structural integrity.
Aluminum 5 3/4-inch I-beam longmembers have an integrated rubber track and rubber riser to significantly reduce shock and noise. The 4-inch stacked "U" shaped crossmembers provide extra load bearing vertical walls. The unit's crossmembers are on 12-inch centers and feature gussets at each crossmember.
DuraClass Alumax has configurations and options to meet the specifications of municipalities and contractors. These options include additional oval light holes, center sliding patchgate, and spill apron. The Alumax is available in a wide variety of lengths, side heights and rear heights.
