The decision between aluminum and steel is not always straightforward, because each material has genuine advantages. Steel is harder, more dent resistant, and less expensive per square foot. Aluminum is lighter, naturally corrosion resistant, and recovers its higher upfront cost through payload gains and reduced fuel consumption over time.
CMV Fabrication builds custom truck beds in both materials and can advise based on the truck's application. A bed that hauls heavy equipment with sharp edges may be better served by steel. A bed on a truck that needs every available pound of payload for materials or tools may be better served by aluminum. The right answer depends on the specific operation.
