Advantage of the side wall semi trailer is its adaptability to different markets and transport needs. Sidewall height, wall thickness, floor strength, and axle configuration can be customized according to cargo type, weight requirements, and local regulations. 

In many cases, the side walls can be partially or fully removable, allowing the trailer to function almost like a flatbed when needed. This high level of adaptability makes the sidewall semi trailer a valuable long-term investment for transport companies that serve multiple industries.
