Project Scope:

With the domestic demand for galvanized steel on the rise, Worthington Steel – America’s largest independent processor of flat-rolled steel, and a major supplier to the automotive industry – needed to add capacity at its 11-year-old steel processing plant in Delta, Ohio. Worthington selected IPS to install a new vertical radiant tube furnace at the plant in order to increase the facility’s ability to generate the heat needed to speed up its processing capabilities.

IPS installed all of the piping, electrical wiring, and rigging for the vertical radiant tube furnace, as well as the support structural steel and concrete foundations.

By upgrading to this new furnace, the plant is able to generate significantly more heat in the same amount of floor space. The additional heating capacity, has allowed Worthington’s Delta plant to increase the throughput rates of its hot-dipped steel galvanizing and slitting lines. Worthington is able to meet increased customer demands in a timely manner, with improved ability to serve its customer base.


The new vertical furnace, which runs up to a height of 90 feet, was built into a section of the plant’s furnace system that had previously housed a 30-ft horizontal tube furnace. To keep Worthington’s shut-down time to a minimum, IPS performed a majority of the work while the plant was in operation.

Project Scope:

North Star BlueScope Steel is a 50-50 joint venture between BlueScope Steel (Melbourne, Australia) and Cargill, Inc. (Minneapolis, MN). The partnership brings together expertise in electric furnace steel making, slab casting and hot rolling technology in a synchronous flat rolled mini-mill. The steel mill is designed with a unique combination of proven technology to provide our customers a superior hot rolled product.

IPS was the mechanical contractor for installation of a new rolling steel mill at the Delta, Ohio facility. IPS self-performed all piping work and some electrical work.

Additional work in the Wastewater Treatment Building required IPS to install: 3 chillers, 12 large sand filter units, 2 circulating pumps, 2 filtration pumps, drag skimmers, weir pit, gravity settle tank, and associated piping.


The initial design was conceptual only, requiring IPS to work closely with Lockwood Greene, an engineering firm headquartered in North Carolina, to complete the final design. Throughout the design process IPS provided valuable engineering and constructability reviews for all above‑ground and underground piping.
