When speak of sheet metal for trailer sides, it is generally made of aluminum alloy sheet 5000 series. In the past few years, many trailer manufacturers used steel plates, but after time, it was found that the steel plates were prone to rust and corrosion, which greatly shortened the service life of the trailer. At present, the market is gradually replacing the previous steel plates with aluminum plates. Aluminum alloy plates have good oxidation resistance, corrosion resistance and excellent rust resistance. In addition, the quality of aluminum alloy plates is lighter than steel plates so they are used in the carriage body of a trailer is a good choice.

Common aluminum sheet metal for trailer sides include 5083 and 5454 aluminum alloy plates. The 5000 series aluminum alloys are mainly aluminum-magnesium alloys, which have good corrosion resistance, excellent weldability, good cold workability, and medium strength. Advantages of aluminum sheet for trailer sides are:

1, The aluminum sheet metal used in the trailer side can reduce the overall quality of the whole truck to a certain extent, realize the lightweight of the trailer body, thereby reducing the emission of carbon dioxide, improving the fuel efficiency, and ensuring the energy-saving effect to a greater extent;

2, Aluminum alloy plate has the characteristics of good oxidation resistance, corrosion resistance, and excellent rust resistance. The aluminum alloy trailer has a long service life; at the same time, it is easy to process and shape, which reduces material waste and is economical and practical;

3, The welding performance of the trailer body is greater, which increases the safety factor of the vehicle;

4, The weight of the aluminum sheet metal for the trailer sides is light. Under the same weight of the iron trailer and the aluminum trailer, the aluminum trailer carries more goods;

5, Aluminum alloy is easy to recycle and more environmentally friendly.
