What is the stanadard diameter size for metal poles used in residential wood fencing? Are there other sizes?

I have a 6 foot tall wood fence with metal poles that are sunk in a concrete retaining wall. I need to redo the fence to be an 8 foot fence, and am hoping that I can add to the existing metal poles to allow for a taller fence. One of the ways I hope to do this is to add length to the tops of the existing poles or to place smaller or larger poles inside or around the current poles.|||Steel pipe come in 6 meter(about 20 ft) standard length,and come in many sizes and class.A,B,C.D.E(thickness)0.5 %26quot;.0.75.0.75%26quot;,1%26quot;.1.5%26quot;.2%26quot;.3%26quot;4%26quot;6%26quot;.8%26quot;and .........Get one that suit you,for outdoor application ,strongly suggest you buy galvanized pipe for rust corrosion|||What an odd combination???





First of all, you may want to check local codes,,,IE: in the US, counties and cities have specific codes they enforce for many things, one perhaps being fencing height, in your area. You may also have to purchase a permit? If that isn%26#039;t an issue then I suggest,,,





Galvanized pipe, such as that sold for chain link fence, in a larger inside diameter or smaller outside diameter than the existing pipe, cut to size allowing extra for the fit. Certainly it would be best if the fit is snug, but you can take the effort to drill and bolt,,,or clamp at the joint? Seems labor intensive to proceed this way, in any case.





If I was contracted to do the job, I%26#039;d pull the metal poles, dispose of them, and use treated 4 x 4 posts, no less than 10 ft. long with no less than 2 ft. buried, then frame the fence posts for support and add fencing material.
