Cheapest trailer in the world?

[KingNothing]

My friends and I are having a little challenge. We want to come up with the cheapest open-top, but sided cargo trailer possible. It must use completely new parts freely available from local steel/wood/plastic suppliers and be capable of hauling around 800lbs. Labor must be something that your typical hobbyist woodworker or welder could do.

My idea is something like this: have the sides and floor of the trailer made of one piece of heavy duty expanded steel, bent as appropriate. Attach an axle or two individual wheels on the sides. However, I'm having a lot of trouble finding the cost of such metal.

I'm really looking for expanded steel where the steel strands are about 0.5" This should make it strong enough to hold its own structure and take quite a load. It would be awesome if I could find that rubberized stuff you're likely to find in a factory or construction site.

Ideas?

Expanded steel is somewhat pricey, and I don't think that it would be suitable for such a use unless braced with angle iron or similar material. I'd be more inclined to go with 1/2" plywood.

I would recommend conducting thorough research on the availability and cost of materials before proceeding with your idea. Expanded steel may be a cheaper option, but it may not be strong enough to withstand the weight of 800lbs. It is important to consider the strength and durability of the materials used in order to ensure the safety of the trailer and its contents. Additionally, I would suggest exploring alternative materials such as aluminum or composite materials, which may be more lightweight and cost-effective. It may also be beneficial to consult with a professional engineer to ensure that the design and construction of the trailer meets safety standards.
