Aluminium trailers vs steel trailers    

                                               

There is, in fact, a lot of conflicts over which one is superior, an aluminum trailer or a steel trailer. Given that aluminum trailers are way more expensive than steel trailers, you may want to have a clearer idea about the performance of both. This article will give you a guidance regarding both the products while also clarifying a few myths.

When aluminum trailer NZ first came out in the 1970s, they were considered to be quite revolutionary in the automobile industry. Aluminum trailers were quite sturdy and also reduced the overall weight of a carriage by a great deal. This resulted in more mileage and hence economy in fuel consumption. The reduced weight also ensured that the tires did not wear away easily, thus doing away with the need for frequent replacement. However, the greatest advantage is that aluminum tires are rust resistant as compared to steel tires and also do not corrode easily when exposed to rough weather conditions.

However, steel trailer manufacturers claim that aluminum trailers cannot take heavy loads like steel trailers and cannot resist stress on roughly built roads. This may leave you wondering if aluminum trailers are worth the investment. This is discussed in detail in the following points.

  1. Metallurgy of the metals

It is quite common to see steel being used as the core constituent of tough items, while aluminum is more prevalently used for packing cans and foils. This may cause some doubt as to whether aluminum can really take the load of a vehicle. However, one point worth mentioning is that the trailer NZ use aluminum alloy and not the pure metal. This is similar to steel being an alloy of iron. In aluminum trailer NZ, 95 % of the total constituent is pure aluminum and 5 % accounts to chromium, zinc, titanium and copper. Using these metals in trace amounts helps to increase the strength and longevity of the trailers. As a result, both the steel and aluminum trailers have the same yield strength.

  1. Cost of maintenance

If you are using aluminum trailers, you will want to frequently clean the exterior to clean away corrosive acid layers. This can be done simply by using water. Aluminum trailers also tend to get dull after a certain period of time. Hence, they need to be given acid baths every once in a while to keep them looking new.

Steel trailers are either galvanized or painted to keep them from corrosion. You will be required to frequently check for scratches as this will eventually lead to rusting. You are also required to frequently inspect if the screws and hinges are in the right condition. At the end of the day, maintaining steel trailers is more expensive as compared to maintaining aluminum trailers.

  1. Resale value

Steel trailers tend to rust out very fast. In a couple of years, they can start to look very old, which will greatly affect the resale value. Aluminum trailer NZ, on the other hand, is more corrosion resistant and an acid bath will keep them looking new for decades. Consequently, aluminum trailer NZ have a greater resale value as compared to steel trailers.
