metal ramp

how can I rid myself of my ramps so I can expand?

c4 or grenades

How many c4?

I thought you could break metal ramps? Metal stairs too? just like wood stairs and ramps, have not tested this tho.

All single objects (campfires, benches, furnaces, etc), shacks, wooden doors, both ramps, and both stairs can be hit with a rock, pick axe, or hatchet and broken. Everything except for foundations, pillars, and ceilings can be destroyed with c4 or grenades.

Ramps can be pickaxed down, whether metal or wood. I forget the count but it can be done. Same for stairs.
