FlexFence - 1" strands - 2 high tensile wires covered in polymer plastic (in white). I would use four strands and possible one strand of electric wire on top if needed. How does this stand up to horses pushing on it? Does it stretch much? Does it seem to last in the weather? This is also available in 4" and 5" strands, but gets very expensive.
Polymer coated high tensile wire - this is single stranded high tensile wire covered in a 1/4" poly coating. They use this at the stable where my horses are now, but it seems to stretch and the polymer separates from the wire. It is not installed properly however, as it is nailed to the fenceposts. I belive it is supposed to be able to slide through the fasteners. Again, I would use four strands.
Does anyone have any feedback on these two types of fencing materials? Any other suggestions?
