When it comes to the sheet metal used for the side of the trailer, it is usually made of 5000 Series Aluminum Sheet Plate. In the past few years, many trailer manufacturers used steel plates, but over time, it was found that the steel plates were easy to rust and corrode, which greatly shortened the service life of the trailer. At present, the market is gradually replacing the previous steel plate with aluminum plate. Aluminum alloy sheet has good oxidation resistance, corrosion resistance and excellent rust resistance. In addition, aluminum alloy sheets are lighter in mass than steel sheets, so they are a good choice for the carriage of a trailer.
Common aluminum sheet metal used for trailer sides includes 5083 and 5454 aluminum alloy sheets. 5000 series aluminum alloys are mainly aluminum-magnesium alloys, which have good corrosion resistance, excellent weldability, good cold workability and moderate strength. The advantages of aluminum sheets for trailer sides are:
1. The aluminum sheet metal used on the trailer side can reduce the quality of the whole vehicle to a certain extent and 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. The 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 form, 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 4 x 8 aluminum sheet used for the side of the trailer is light. Under the same weight of iron trailer and aluminum trailer, aluminum trailer can carry more goods;
5. Aluminum alloy is easy to recycle and more environmentally friendly.
