Understanding correct terminology—such as A-pillar, rocker panel, or trunk lid—is essential during insurance claims, repairs, or sourcing replacements 2. Whether restoring a classic car or repairing collision damage, knowing what each panel is called helps ensure accurate communication with mechanics and suppliers. This guide breaks down types, materials, costs, and key evaluation criteria so you can make an informed decision when buying car body panels.
About Panel Board for Cars, What Are the Panels on a Car Called?
The term "panel board for cars" may be misleading—there isn't a single component known as a "panel board." Instead, vehicles use multiple individual metal or composite body panels that form the outer shell. These include structural and cosmetic parts such as fenders, doors, hoods, bumpers, and roof panels. Collectively, they’re referred to as automotive body panels.
Exterior panels serve several functions: protecting internal components, shaping aerodynamic performance, absorbing impact energy via crumple zones, and maintaining unibody rigidity 1. Interior panels—like dashboards, door trims, and pillar covers—are typically made from plastic, vinyl, or fabric and contribute to comfort and sound insulation.
Common naming conventions often use location-based labels:
- 📍Fender: Covers front wheels
- 📍Quarter Panel: Rear side section behind doors
- 📍Rocker Panel/Sill: Below door openings
- 📍Hood/Bonnet: Engine compartment cover
- 📍Trunk/Boot Lid: Rear storage access
- 📍Pillars (A, B, C): Vertical roof supports
Knowing these terms ensures clarity when ordering replacements or discussing repairs.
