Aluminum vs. Steel Trailers

There are many similarities and differences between aluminum and steel trailers. When deciding which type of trailer may be right for you, consider these 3 important factors


Corrosion is a huge factor to consider when choosing a trailer. So, which material holds up best against rust and corrosion? The answer is clear. 

Aluminum can resist rust because it contains no iron or steel. Aluminum trailers don’t require any corrosion maintenance and will last for years as-is. 

Steel rusts easily when exposed to water. Steel trailers require regular maintenance and rust-preventive solutions. Steel trailers often need indoor storage to protect them from the environment and elements. 


Aluminum trailers are more expensive than steel trailers. However, when you factor in the cost of the maintenance on steel trailers – the cost of an aluminum trailer is probably cheaper than steel in the long run. 

Steel tends to resell at lower rates than aluminum trailers due to the longevity and corrosion factors listed above. Even if your steel trailer looks brand new, it will ALWAYS require ongoing maintenance which adds up in cost over time!


When it comes to the strength of the trailer, there is one clear winner: Steel. Steel contains various other materials to enhance its hardness and durability. Steel is more resistant to bending, whereas aluminum is more flexible and resistant to shocks. 

Technically, steel is stronger than aluminum. Steel materials have more elasticity, which means more force must be applied to steel before it starts to bend. However, aluminum flexes three times as much as steel. This means that aluminum is more likely to spring back to its original shape after being stressed, whereas steel may always stay bent. Steel’s rigidity makes it more vulnerable to cracking.

The right metal for your trailer

In conclusion, aluminum is a superior manufacturing material for trailers. While a steel trailer can do the job, an aluminum trailer almost always does a better job and lasts longer.
