At MAR-MAC INC. in the small town of McBee, South Carolina, robotic arms coil 335 feet of steel wire into a roll four-and-a-half inches in diameter. It is then dropped onto a conveyor belt. Where workers package it into boxes.
This rebar tie wire is the core of MAR-MAC owner John Martin’s business.
“Anytime you build a bridge, a dam,” he said, “you may very well be using our rebar tie wire.”
