Why steel bodies truck is better?

Strength & Durability
Steel, with 2.5 times the aluminum density, is known to be solid and robust. When choosing a hardworking truck that can survive years of strenuous use, this is a significant contributing factor. Steel bodies are suitable for heavy duty work (much of the industry uses galvanized steel).
For example, a landscaper can find steel more resistant to the effect of loading/unloading significant hardscaping materials, such as boulders and rocks. So, whether you're trying to carry heavy material or machinery, steel is what you should think.
Corrosion Resistance
Rust is one of the biggest enemies of a truck, and it can practically eat holes in the truck body and engine. Rust will spread rampantly until it is confined and fixed. Steel makers paint the metal surface with a galvanic zinc layer to prevent the creation of rust. It’s now best to be compared with the aluminium since both would not face rust easily.
Safety
It is a very normal and long-standing belief that steel provides more structural stability and thus more protection to the drivers driving the car. However, in recent studies on steel trucks and aluminium frames, the latter has proven itself to be a worthy competitor in terms of safety.
