Our Products

Hot rolled steel sheet is the primary form of steel produced by the Flat Roll Group, Columbus Division. Our capabilities range from formable low-carbon grades to ultra-high-strength steels, with certification available to various ASTM, SAE, JIS and API standards.
 
Our six stand hot-strip mill enables us to produce the lightest-gauge hot rolled steel in North America while maintaining the most precise gauge control available in the industry. As a result, our unprocessed hot rolled bands and our processed hot rolled steel sheet are used in a variety of demanding applications by manufacturers in the agricultural-machinery, automotive, appliance, construction, heavy equipment, lawn and garden, pipe and tube, racking and truck-trailer industries.
 
Although we have the capacity to produce more than 3.4 million tons of hot-rolled steel sheet each year, a significant portion of this material is finished in our cold-mill complex before being shipped to our customers. The Columbus Division operates three metallic-coating lines with diverse capabilities to better serve a broad range of customer applications. Each of these lines incorporates temper rolling and tension leveling to ensure excellent surface and shape characteristics.

Markets
Flat rolled steel products represent the largest portion of the domestic steel market. Our steel sheet products are used in the manufacturing of automobiles, appliances, construction products, consumer electronics, agricultural products such as culverts and grain bins, office furniture and pipe and tubing for the oil and natural gas wells. The following chart shows the U.S. shipments of these products, as reported by the American Iron and Steel Institute (AISI).

Painted Steel Products

The Flat Roll Group, Columbus Division, operates a state-of-the-industry continuous coil-coating line, enabling us to streamline supply chains for customers using pre-painted steel. Our coil-coating lines are integral to our finishing facilities at Columbus, allowing us to exploit our industry-leading cycle times to produce prepainted steel more quickly than any other supplier in the nation. The elimination of a third-party toll coater also allows our customers to avoid altogether the logistical expenses typically associated with moving steel from the producing mill to a coil coater for toll painting. Additionally, there is no coater-fault yield loss associated with our business model—this can be a significant savings opportunity since we capture and immediately recycle any yield loss at our facility.

Even more important than our industry-leading cost and lead times, is the fact that our coil-coating lines are equipped with tension levelers and high-definition surface inspection systems to ensure that we consistently achieve the highest-quality standards. Customers in a variety of industries use our prepainted steel in the manufacture of appliances, consumer electronics, garage doors, lighting, office furniture, purlins, roofing, siding, truck trailers and school buses.
