Aku cargo trailers are divided into two series: CS marked – bolt and rivet frame trailers; CP marked – fully welded frame trailers. Bolt and rivet cargo trailers are made from sheet metal cut and bent parts. The fully-welded frame is, as the name suggests, a single unit. The base frame and side port elements are welded together from laser-cut tubes and then hot-dip galvanized as a whole. Aku welded frame cargo trailers also have hatches on the welded frame.
