What uses do aluminium square box sections have?
An Aluminium Box Section has excellent corrosion resistance – it is perfect for outdoor applications as it will not rust. It is a lightweight product, just a third of the weight of a steel box section, and it is excellent for welding. Therefore, an aluminium box section is often used to manufacture welded frames and bearers for applications such as:
Commercial vehicle bodies
Aluminum square boxes offer a superior strength-to-weight ratio, enhancing fuel efficiency compared to steel. Aluminum’s natural resistance to corrosion, through the formation of an aluminum oxide protective film, prevents rust caused by oxygen.
Trailers
When towing a trailer, a specific level of engine power is essential. Aluminum square box sections reduce these power requirements due to their lighter weight compared to steel.
Horse boxes
Similar to the trailer, a horse box has to be strong enough to take the weight of a horse, but also light enough as to be able to tow the horse.
Caravans
Due to how easy it is to weld aluminium square box sections together; it allows for new and exciting designs in caravan building.
