The products manufactured by Doepker Industries are used in three distinct industries. For the agricultural community, Doepker Industries produces the bulk trailer (in both steel and aluminum) which is used to haul grain and other bulk commodities. Equipment trailers for the agricultural machinery industry are also becoming an important line.

For the commercial market, a wide variety of flatdeck units are manufactured: Premium, Econo, LoProfile, Super Lite, Drop Deck, Utility, and Heavy Duty models.

Furthermore, with the addition of logging trailers, a significant portion of sales comes from the forestry industry. Doepker Industries also markets a number of specialty trailers including fold-down models, and the company has long served the transportation industry with custom designed solutions to specific problems. An order for standard production models such as single tandems and tridems, lift axles, and Super B's can specify a multitude of options.
