I'm sure they could use some over-engineering if you wanted but they work great. After putting the Bronco on them I tried to move it as much as I could and the thing is solid as a rock. And as far as the C-channel goes it would take a ton of force to knock them out of the current cradels that are there now, not sure how some thick C-channel would make it any better.
Either way they work way better than a common jackstand with or without improvements.
