Yes. 48′ and 53′ long and 8′ high walls are the most popular. Of course, we make custom sizes as well. 99.9% of the units we make have walls and floors of Hardox (TM), which is a special high strength steel. This means we make the units light, but heavy duty and high quality. Importantly, this allows them to carry the most weight possible and have high uptime. Also, like our other trailers they have 102″ wide axles. Moreover, instead of a ‘stitch’ weld at the bottom wall as it meets the frame, we have a continuous weld for longer life.
