Bottom Rail
The bottom rail of a semi-trailer is a structural component that runs along the lower edge of the trailer’s side walls. It provides structural support and protection for the trailer, and acts as an attachment point for side panels and flooring.
Functions
Structural Support: Provides strength and rigidity to the trailer’s frame, helping to maintain its shape and integrity.
Attachment Point: Acts as a mounting surface for the trailer’s side panels and flooring.
Protection: Shields the lower edges of the trailer from damage caused by road debris and impacts.
