Our range of popular trailer designs take the guess work out of trailer building with detailed drawings, material cut lists, images, DXF and more. Trailer builders don’t have to navigate complex technical requirements, ADRs or Vehicle Standards Bulletins, as all requirements have been applied to the specific trailer plan in hand.

Our focus is largely on chassis structural design and satisfying minimum ADR (and other relevant legislation) strength requirements.A professionally prepared design package will help to get your trailer build project underway with confidence.
