    I like how you talked about steel and aluminum in terms of how strong they are being dependent on the alloy in question. I would think that the mixture of metals would change the density and strength and go into the decision process. Thank you for the information about how they two metals are usually comparable as far as strength.

      Good observation. Interestingly, the alloying of Steel and Aluminum only changes the density slightly — insignificant in practical terms. The strength, on the other hand changes a lot. The way it is processed, like heat treatment, also makes a huge difference. This topic is a good idea for a future post. Thank you.

    Great article. I would also like to know what size of material would be use and frame type for different size of trailers. Example would be a 16 ft flat deck 10,000 lb capacity trailer VS a 20 ft flat deck with 14,000 lb capacity. Is there a formula or a web site that would show what is the best way a trailer is build and have the correct size of material. Aluminum or steel.

      Yes, there are formulas, but they are not as simple as it might at first sound. The biggest issue is knowing what materials — channel, tube, angle, I-beam — then the sizes, combinations, and configuration. So many variables. Posting something to get you going is a good idea, so I’ll keep that in mind. Thanks.
