Aluminum vs Steel Box Truck Bodies in the EV Era

Aluminum box truck bodies are lighter and resist corrosion, which helps offset heavy EV battery weight and extends range, while steel is stronger and often cheaper to repair. In the EV era, aluminum's weight savings make it increasingly attractive despite its higher repair complexity.

Why Weight Matters More With EVs

Electric drivetrains carry heavy battery packs, and every pound of body weight cuts into payload and range. Aluminum bodies shed significant weight versus steel, which is why more EV and hybrid box trucks lean toward aluminum construction to protect their working capacity.

How Do They Compare?

• Weight: aluminum is significantly lighter, helping EV range and payload
• Corrosion: aluminum resists rust better in wet Inland Empire seasons
• Strength: steel handles impact and structural loads well
• Repair: steel is often simpler and cheaper to straighten and weld
• Cost: steel bodies usually carry a lower upfront price

What Does This Mean for Repairs?

Aluminum requires different techniques than steel. It cannot be worked identically, and repairs demand more care to preserve strength. Steel is more forgiving to straighten and weld. A shop that handles both matters as Corona fleets run a mix of older steel and newer aluminum trucks.

Corrosion is the other big factor. Aluminum shrugs off the moisture that rusts steel, but where the two metals meet, galvanic corrosion can start, so those joints need proper attention during any repair.

Steel or aluminum, EV or diesel, the goal is a repair that restores strength and finish. We work both across the Corona and Inland Empire fleets we serve.

Which Should a Fleet Choose?

There is no universal answer. If range and payload drive your electric routes, aluminum's weight savings often win. If lowest repair cost and rugged simplicity matter more, steel still makes sense. Many fleets will run both for years, so plan your repair partner accordingly.

The Repair Reality

Whatever the material, body labor runs $210 per hour and the aim is the same: a straight, strong, corrosion-treated, properly refinished body. The metal changes the method, not the standard your Corona trucks need to stay safe and on the road.
