Due to the innovative raw materials employed in production, our skeleton trailer could be divided into two types, the aluminum alloy skeleton trailer and the other our high strength steel skeleton trailer. Our aluminum alloy skeleton trailer is made of aluminum alloy profiles from Shandong Yuhang Special Alloy Equipment Co., Ltd. In this way, an improved strength and decreased dead weight is achieved. Our high strength steel skeleton trailer adopts high strength steel as the raw material for both its chassis and body panel, providing greater strength and less dead weight. A custom skeleton trailer option is also available at Sanxing. Our skeleton trailers are mainly used to carry standard or nonstandard containers.
