Custom built trailer fabricators

Ultimate Plant Trailers is an Australian owned and operated business, based in Geelong Victoria. We manufacture trailers custom built to your needs. With over 35 years of experience in custom fabrication, we get your combination right.

It’s all in the details

From concept to design our team will work with you to custom build your trailer to suit your needs. Beginning with a personalised conversation, we get to know you and your unique requirements.

For every trailer we produce 2D and 3D CAD drawings, so you can visualise and customise your trailer before production. We do this to ensure satisfaction is upheld throughout the build and you get what you want the first time.

From slide out hidden toolboxes to equipment attachment housings and wells - we’ve got it covered.
