Seize The Advantage


More than great looks, Castleton’s clean, minimalistic design makes it attractive and productive. This design is followed through on all of the Castleton and Superior product lines making these trailers exceptional, long lasting, and ready for work.


The Castleton and Superior line of trailers are built for production.  They are made from high strength steel and North American components.  These trailers not only minimize downtime but also give you maximum payloads.


In conjunction with modern technology, efficient manufacturing processes and stringent quality control practices, Castleton is proud to be the first member in SSAB`s My Inner Strenx program.  High quality structural steel from Sweden made to top industry standards allows Castleton to make a longer lasting, higher Strenx trailer.
