The Heartland Division’s galvanizing line applies a thin layer of zinc to full-hard cold rolled steel for superior corrosion protection. The galvanizing line boasts in-line tension leveling and a four-high temper mill for enhanced surface quality. At 72” wide, the process capability ranges from 0.010” to 0.060” in thickness. Available zinc coating weights range from G30 to G115.
