Flatbed Trailer Plans
$ AUD
A flatbed trailer is one of the most versatile and useful trailer types you can build. Whether you’re transporting cars, machinery, materials, or farm equipment, a flatbed design offers unmatched flexibility and loading convenience. At Fabplans, we’ve engineered a range of DIY flatbed trailer plans that are strong, reliable, and simple to build from your own workshop.
What is the best size flatbed trailer?
The best size depends entirely on what you’re hauling. Before you start your build, consider:
- Storage space: Do you have a large enough area to store the overall length of your trailer?
- Weight capacity: If you plan to carry heavier loads or equipment, you’ll need to build a trailer with a higher ATM (Aggregate Trailer Mass). Keep in mind the capacity of your tow vehicle.
- Functionality: Would you prefer a standard flatbed trailer, or do you want to add features like hydraulic tipping, drop-down sides, or custom tie-down points?
For many DIY builders, the flatbed trailer is the perfect balance between practicality and performance—easy to load, adaptable, and built to handle years of use.
Engineered for Strength & Performance
All Fabplans flatbed trailer designs are professionally engineered, FEA-tested, and proven through real-world use. Our plans are developed using years of fabrication and design experience to ensure you get a DIY-friendly build that performs to professional standards.
Each plan includes:
- Detailed engineering drawings
- Parts and cutting list to simply ordering
- Assembly diagrams for fabrication guidance
- Information booklet to guide you through the build
We take pride in producing plans that are accurate, safe, and customisable, so you can build a trailer that fits your exact requirements.
The Perfect Foundation for Custom Builds
A flatbed trailer can also be the ideal foundation for countless custom projects. Many builders use our flatbed plans as the starting point for:
- Tiny home trailers
- Stock floats or horse floats
- Plant and machinery trailers
- Enclosed trailers or mobile workshops
- General-purpose transport trailers
Because of its open-deck design and modular structure, the flatbed is one of the most adaptable trailer bases available. Whether you’re looking to add side walls, build an enclosed box, or mount a structure on top, our flatbed trailer plans provide a strong, balanced, and road-legal foundation for almost any project.
This makes it the ideal choice for builders, tradespeople, and creative DIYers who want the flexibility to modify or expand their design in the future.
Choosing the Right Number of Axles
When selecting your trailer configuration, the number of axles is an important design decision. While our plans may display a particular setup visually, the final choice is up to you.
Each configuration has its pros and cons:
- Single Axle Flatbed Trailers – Ideal for lighter loads and smaller builds (up to around 2800kg). They’re easier to manoeuvre, more affordable to build, and perfect for tight spaces.
- Tandem Axle Flatbed Trailers – The most popular choice offering excellent load distribution, smoother towing and a strong balance between cost and performance. They’re ideal for most DIY builders.
- Tri-Axle Flatbed Trailers – Best suited to long trailers or trailers requiring extra weight carrying capacity, such as mobile homes or large machinery carriers. While they offer exceptional weight capacity, tri-axle setups experience higher wear and tear on tyres and suspension due to increased scrubbing during cornering.
If you’re unsure which setup best suits your build, get in touch with Fabplans. We’ll help you choose the right configuration for your needs.
