Custom Trailer Fabrication

At Willie’s Manufacturing Industries, we are available to produce custom trailer fabrication for our clients’ needs. We understand that sometimes you may need custom farm machinery, made specifically for your requirements, and are here to assist in any way we can. We are a family-run business, based out of Warrnambool in Victoria, and all of our products are manufactured in Australia. 

Read on to find out about some of the custom trailer fabrication we can complete, a little about the feeders we manufacture, and a bit about who we are as a company. 

Custom Trailer Fabrication

WMI can create a range of custom trailers for clients after something unique to their needs. As a company, we can make a wide variety of trailers, from bale feeders to box trailers. At WMI Feeders, we understand that your needs can be as unique as your business, and as such, we aim to create a custom product that suits your business, and that you’re excited to use. We can produce custom trailers big and small, plus all those in-between. All of our products are made from high-quality materials, and we cover them with extended warranties. Please get in touch if you have a custom trailer fabrication project that you’d like to make a reality.

Who is WMI?

WMI first began in April 2009, when Jason Willie and his father Wayne took over Carroll’s Manufacturing Industries. At this point, Jason had already completed his apprenticeship in engineering and fabrication with Carroll’s. He was also heavily involved in the design and production of the popular Pa-Mick and Albybone bale feeders, along with other farm machinery. As a business, we specialise in manufacturing bale feeders, as well as a wide range of general fabrication (including custom trailer, trailer tow hitch, and steel fabrication). Since taking over Carroll’s, we have released two new machines into the market: the Ellie round bale feeder in 2010, and the Champion multi bale feeder in 2012. We employ four staff members, which includes three apprentices. 

WMI utilise modern technology in the design of our machines, something we believe sets our products apart from many of our competitors. We ensure customer satisfaction by producing quality products. One testament to our product quality is the fact that the first machine we ever made is still going strong after 17 years! 

While we are based in Victoria, we supply our products to a range of dealers across Australia, stocking to dealers in New South Wales, South Australia, Queensland, Western Australia, and Tasmania.

If you are interested in our fabrication services, and would like to make a custom order, please get in contact with us! We are always happy and excited to talk to our clients about their custom trailer fabrication ideas, and how we can work to bring them to life. Alternatively, if you are interested in any of the other products we manufacture, feel free to reach out to us or any of our dealers for more information.
