Overview

Doepker’s Steel Flat Deck is the benchmark single unit flat deck all-steel construction that rivals the tare weight of aluminum/steel combo flats of the same spec, without giving up the structural advantage of full steel. At 53′ long and 8½’ wide, with a INTRAAX AAT-23K-LDA-14 Air Ride on a 4′ sliding suspension, it handles the full range of commercial freight with the confidence of a 37,500 kg GVWR behind it. The same 100% cold galvanization/zinc exterior, PPG epoxy primer, and heat-oven-cured urethane topcoat that protects every Doepker flat deck.
