Worthington Steel, Delta, Ohio
Dunbar completed the installation and all associated piping for this new operation in 1996. Dunbar continues to provide maintenance, shut down and process improvement services. Systems include:

  • Pro-Eco pickle line.
  • Hot dip galvanizing line.
  • Selas furnace.

Services which have been performed for this multi-story galvanizing line operation include:

  • All process structural steel.
  • All process machinery and material handling system.
  • Filter press addition.

Two decades later, Worthington brought Dunbar back to replace 90-feet of the annealing furnace, adding 21 feet in the process to further improve quality and galvanzing capacity. Dunbar’s crews minimized downtime by pre-assembling
platform sections as modules on the production floor and set 90-tons of steel plus 90-feet of pre-heat modules, including all terminal equipment. Only 16 days total were required from the start of construction to the start of production.

In 2018, Dunbar again worked for Worthington Steel to replace two burner sections at the lower end of the pre-heater. Dunbar crews cut the existing bracing away to allow removal of the two lower burner modules, supporting 90-feet
of furnace by installing temporary structural bracing. This was accomplished over a ten-day shut down period.
