If girlfriend leave your 3" quarter Pipe outside, then you"ll need to protect it somehow or the aspects will begin to tear it down before you also have a possibility to wreck going off of it.

Some other suggestions:

You can develop the entire ramp the end of push treated lumber. This will aid it last longer, but it will cost much more to buy. Also, as you reduced it, don"t breath in the sawdust - the chemicals they law the wood v is harsh.You have the right to paint it.
