Are the PC Board Ties copper plated on both sides of the tie? May 10, 2019 19:22 Yes. We use double sided copper material for PC board ties. Our pre-gapped crossties are only gapped on one side. Related articles Can I get pre-gapped ties? Why are the crossties available at the same thickness as wood ties, but the turnout ties are not? Your PC Board Ties don't match the thickness of wood ties. Won't that be a problem? Won't the copper plating cause a dead short? I have purchased PC Board ties before and they were always twisted. Are yours twisted as well?
