They are regular containers when up, but when folded they are just big flat heavy pieces of freight - so you can load them as any other 40' long piece of freight but that means extra handling gear, forklifts, cranes etc at the customer's site to collapse them.<p>You can put them on flat rack, but those are a pain to handle as well.
Now if eg. 10 of these folded flat could lock together and be the same height as a regular container and and be handled as a regular container that would be great.<p>Frankly when you can pay &#60; $1000 for a new steel container in China nobody is going to be buying expensive, unproven composite containers however clever.
