Steel Grain Trailers

Designed by Grain Harvesters

Demco Manufacturing is the leader in the industry for steel grain hopper trailers. Designed for the grain harvester by the grain harvester, our steel grain trailer is known as the work horse in the industry. 

Our heavy wall tubular steel frame has been designed to minimize twisting.  Hopper and wall skins are 14 gauge steel to provide the durability that our customers demand.  Our standard 66” side walls provide a full view into the hopper from the combine cab.  Demco’s exclusive horizontal rib wall construction significantly reduces air drag and rock chip damage which equates to fuel savings and extended paint life.
