Metalbody

Metalbody refers to a type of vehicle construction where the primary structural components and exterior panels are made of metal. This contrasts with materials like fiberglass, carbon fiber, or wood. Historically, metal bodies, particularly steel, have been the dominant form of automotive and aircraft construction due to their strength, durability, and cost-effectiveness.

The fabrication of metal bodies typically involves stamping, welding, and shaping sheet metal. Steel has been the most common material, offering a good balance of rigidity, impact resistance, and ease of repair. However, concerns about weight and corrosion have led to the increased use of other metals like aluminum and its alloys, especially in high-performance vehicles and aircraft where weight reduction is critical for fuel efficiency and handling.

Modern vehicle manufacturing often employs advanced high-strength steels (AHSS) and aluminum alloys to create lighter yet stronger metal bodies. These materials contribute to improved safety through better crash performance and enhanced fuel economy by reducing overall vehicle mass. The design and assembly of metal bodies are complex processes involving sophisticated robotics and manufacturing techniques to ensure precision and structural integrity. The term metalbody can also be used in a broader sense to describe any object or structure primarily composed of metal.
