Should You Buy An Aluminum Or Steel Trailer?

Choosing a new trailer often comes down to picking the best material for your needs. Two of the most common choices are aluminum and steel. Both materials are readily available for most trailer designs, from a small utility trailer to a large flatbed or horse hauler. The following guide will help you compare the two materials so you can make the best choice before you purchase.

Weight and Durability

The metals used for both steel and aluminum are alloys, which means they are mixed with other metals. In the case of aluminum, it is combined with stronger metals like copper and titanium, so that is is just as strong and durable as the steel alternative. Steel is an iron alloy, which means it is strong but also heavy. Aluminum trailers often offer similar durability as steel, but at a lower weight. This means they can carry a heavier load without putting stress on the towing vehicle or requiring as much fuel use.

Rust and Corrosion

Corrosion is mainly an issue with steel. As an iron alloy, steel can rust easily, so it is usually sealed to help prevent this. Small scratches and normal wear and tear can expose metal through the seal or paint, necessitating a quick repair and patch before the rust causes irreversible damage. The undercarriage, bed, and locations around bolts are the most prone to rusting. Aluminum does not rust, but it can corrode if exposed to an acid. This is mainly a concern in livestock trailers since urine is acidic, but rinsing the trailer out after each load can minimize this concern.

Standard Maintenance

Beyond rust and corrosion issues, both types of trailers require similar maintenance. Any finish, such as paint, should be reapplied periodically if it becomes damaged or begins to wear through. Steel trailers do tend to need painting more often, though, due to the aforementioned rust issues. This means they can be more expensive to maintain than aluminum. Hinges and other moving parts will require regular lubrication to ensure they continue to move smoothly. All welds and bolts should also be inspected regularly, perhaps once a month, to ensure they are in good condition and that the bolts aren't loose or missing.

Contact a trailer dealership in your area to see the options first hand. This way, you can examine both and make a decision as to which one will serve your purposes best.
