Which component is commonly classified as a non-structural panel?

• A. Door
• B. Chassis rail
• C. Suspension mount
• D. Engine cover

Answer: (A)

In auto body work, panels are split into structural and non-structural based on whether they carry the vehicle’s main loads. Structural panels form part of the crash energy path and overall rigidty, such as chassis rails and suspension mounting points, which help keep the car’s shape and safety during a collision. Non-structural panels don’t carry those loads; they mainly provide shape, protection, and access. The door is a classic non-structural panel because its outer skin is not part of the primary load-bearing structure, even though it’s attached to the frame. The main strength comes from the frame and pillars, not the door skin. The engine cover also doesn’t contribute to stiffness, but the door is the typical example highlighted in this context.
