Frequently Asked Questions About Trailers
Sizes are described as length x width and are traditionally quoted in feet. Our standard size trailers, with internal metric dimensions, are as follows:
- 6’x4′ (1760mm x 1200mm)
- 7’x4′ (2060mm x 1200mm)
- 7’x5′ (2060mm x 1500mm)
- 8’x5′ (2400mm x 1500mm)
Other sizes available upon request.
Light Duty, Medium and Heavy Duty builds are available for box trailers, as well as optional higher sides (21″).
For custom trailers you will need to nominate the length x width x height expressed in either metres, millimetres, inches or feet.
- Checker plate = 2.1mm
- Smooth (or “hot rolled sheet”) = 1.5/1.6mm
- A trailer without brakes is limited to 750 KG GVM. GVM is Gross Vehicle Mass which means the combined mass of both the load and trailer.
- Trailers with a GVM of 1000 KG – 2000 kg require brakes fitted to the front axle. Trailers with a GVM above 2000 KG require 4 wheel electric brakes & break away switch.
- For custom trailers you need to estimate the maximum load weight so we can determine the appropriate suspension, chassis and braking system required. Accuracy here is critical, as repairs to a damaged trailer due to overload can often exceed the cost of appropriate strengthening at the manufacturing stage.
- For enclosed trailers, you need to specify where your entry points are to be located as well as the style, eg. lift up door, drop ramp, side swing door etc.

- We all know that a galvanized trailer will most probably outlast its owner, however they are more expensive. So here are some tips to get the most out of your painted trailer.
- Upgrading to durra gal chassis and zinc anneal sheets cost less than going to hot dip gal.
- When storing your trailer outside always have the front of the trailer raised to allow any water to run . Jockey wheels are good for this also. If this can’t be done, then drill some drain holes into the floor.
- If possible, cover the trailer with a cheap plastic tarp & in turn use this for covering your loads.
- If you scratch it, touch it up. We sell touch up paint.
- Don’t lend it to anyone.
