SDA Steel and Aluminum Combination Drop Deck Trailer
This single drop trailer combines the advantages of steel and aluminum into one package. The strength of steel is applied in the main rails, front and rear bolster and kneebraces. Aluminum is used in the cross members and the outside rails. The appearance of the trailer is greatly enhanced but more significant is the fact that the overall weight is less than a full steel trailer, yet somewhat greater than the SAC version.
