Vehicle panels constitute the non-structural exterior and interior body components, providing enclosure and aesthetic covering. Typically constructed from stamped steel, aluminum, or composite materials, these panels include body panels like fenders, doors, hoods, and roof sections, as well as interior trim components. Critical features include precise dimensional accuracy for proper fitment, corrosion resistance achieved through coatings or material selection, and increasingly, lightweighting through material choice and design. Panel attachment utilizes methods such as spot welding, adhesive bonding, and mechanical fasteners, demanding precise locating features. Replacement panels must meet original equipment specifications for safety systems integration and vehicle geometry.
