As the steel companies do not charge extra for drilling highrail for bond terminals, we haveassumed the first cost of installingPlug Bonds and Electric WeldBonds on new work to be thesame. The saving in this instance wouldtherefore be due to the longer lifeof Electric Weld Bonds and thedifference in cost of rebonding.
