Turf Questions and Rail Height Questions

I was wondering what most people use for their turf on their summer drop in ramps... I was also wondering wear I should go when looking for my turf. I was thinking Home Depot or Lowes. My thought was some outdoor carpet for decks and what not. I also have heard about the construction fence... AKA Orange stuff with a thick mesh... I was thinking to use it for my flat but I don't know where to go for that either. And finally my last question was about how high the rail should be for the stickyed summer setup tutorial... That is all any help whould be AWESOME!!! Thanks :]
