I'm that unusual guy who actually likes standard patrol steps and use them like rock-sliders.
They can take quite a lot of abuse. In the training that I do the steps/rock-sliders are used as a tool to slide around obstacles and line up for the next obstacle, and those two dedicated training patrols do it all day every day (for 8 years) and the steps still look ok. A little crinkle cut here and there but ok.
Granted though, the majority of the abuse is side pressure rather than taking knocks from underneath
