What TWB Company makes

TWB Company is North America's market and technology leader for tailor welded products: sheets of steel or aluminum of different thickness, strength, and coating joined into a single blank or coil so a part carries the right material in exactly the right place. The company runs four product lines. Tailor Welded Blanks (TWB) join dissimilar steel sheets by laser welding. Tailor Welded Coils (TWC) bring the same idea to coil-fed operations such as progressive dies and roll forming. Hot Formed Tailored Blanks (HFTB) combine press-hardenable manganese-boron grades that reach 1,500 MPa or more after hot stamping, with a HotWire process that can eliminate the ablation step in certain grade combinations. Aluminum Tailored Blanks (AlTB) are produced by friction stir welding, a solid-state process that joins dissimilar aluminum alloys with low distortion.

The output is automotive body-in-white structure. TWB catalogs applications across side frames, B-pillar inner and outer, longitudinal and engine rails, door inners, floor pans, shock towers, wheelhouses, roof members, and liftgates, among others. The value proposition is lightweighting without losing crash performance: putting high-strength material only where a part is highly stressed cuts weight and cost, consolidates parts so an OEM stamps one blank instead of several, and improves nesting so less material is scrapped. The company states that a 25 percent vehicle weight reduction yields roughly a 20 percent cut in fuel consumption, the logic behind tailor welded blanks as a CAFE-compliance tool. The same structural parts increasingly serve battery electric vehicles.

TWB positions engineering support at both ends of the product development cycle. Its services span application development, optimized material utilization, product design, forming analysis, and equipment and process development, plus just-in-time logistics tied to its plant network.

Ownership and history

TWB was formed in 1992 as a joint venture between Worthington Steel and ThyssenKrupp Steel, the originator of automotive tailored blanks. The ownership has since changed hands on the minority side: WISCO acquired ThyssenKrupp's stake in 2013, and Baosteel later absorbed WISCO, so today the joint venture is between Worthington Steel and Baosteel Tailored Blanks. Worthington Steel is the majority owner. Worthington Steel, Inc. became a standalone public company in December 2023 when Worthington Industries separated its businesses, and it now trades on the New York Stock Exchange under the ticker WS, reporting group revenue in the 3 to 4 billion dollar range per its own investor materials.

That structure gives a mid-size North American manufacturer the backing of a public steel processor plus a global tailored-products network. Baosteel Tailored Blanks International operates 29 affiliated production and development facilities across Europe and Asia that TWB draws on for technical and customer support. The company describes the combined footprint as the largest and most advanced tailor welded products operation in the world. Day-to-day, Brad Ranly was named President of TWB Company in June 2026, moving up from Vice President of TWB operations and supply chain.

Locations

TWB is based in Monroe, Michigan, and operates 11 facilities across North America to support just-in-time delivery to automotive assembly plants. In the United States it runs plants in Monroe and Canton, Michigan; two sites in Valley City, Ohio (on Innovation Drive and Wegman Drive); Smyrna and Antioch, Tennessee; and Glasgow, Kentucky. In Mexico, TWB de Mexico operates in Cuautlancingo (Puebla), Silao (Guanajuato), and Monterrey (Nuevo Leon). In Canada, Tailor Welded Blanks of Canada runs a plant in Cambridge, Ontario. The Smyrna site sits on Nissan Drive, adjacent to the Nissan assembly complex, reflecting the co-located, nearshoring model tailored blanks depend on.

Certifications and quality

TWB presents IATF 16949, the automotive quality management standard, and ISO 14001 for environmental management, alongside a Ford Q1 supplier award, all displayed as current on the company's site. The company hosts a Ford Q1 scorecard detail, and Ford Q1 is a customer-specific quality qualification, which makes the Ford relationship a documented one. A legacy TS 16949:2009 certificate also appears on the site and predates IATF 16949, which superseded it.

On the shop floor, TWB integrates real-time weld monitoring directly into its production equipment, checking every weld and flagging defects automatically. The company states it is the only tailor welded blank and coil manufacturer that runs a magnetic flux leakage detection system on every blank it welds. It uses lot-controlled production with full traceability, ink-jetting a batch number onto each finished product so the materials and specifications behind a part can be traced even after forming.

Known customers

TWB serves automotive OEMs and their stamping operations across North America, and most programs are not publicly named. One relationship is documented, and one is a reasonable inference from plant siting.

Sourcing evidence

TWB's feedstock is steel and aluminum coil, and its US operations buy that substrate from domestic mills, including majority-owner Worthington Steel, which moves by truck and rail rather than ocean freight. That is why the US entity leaves almost no footprint in US ocean-import bills of lading. The Mexican operation is visible: TWB de Mexico appears with 90 import shipments, most recently in August 2024, and its named suppliers are European steel mills, ArcelorMittal (Mouzon and Gent) and ThyssenKrupp Steel Europe, plus Wisco Lasertechnik for welding-line equipment. The pattern, steel and line technology in and welded blanks out, is the signature of a blank welder rather than a distributor.

Coverage caveats: these are ocean-freight import records only. Domestic steel purchases, which dominate TWB's US supply, do not appear, and truck and rail movements across the US-Mexico and US-Canada borders are not captured. Absence of a record is not evidence of absence.

Frequently asked questions

What does TWB Company make?

TWB Company makes tailor welded products for the automotive industry: tailor welded blanks, tailor welded coils, hot formed tailored blanks, and aluminum tailored blanks. These join sheets or coils of different thickness, strength, and coating by laser or friction stir welding so a stamped part uses high-strength material only where it is needed, reducing weight and cost. Applications include side frames, pillars, rails, door inners, and floor pans.

Who owns TWB Company?

TWB Company is a joint venture majority-owned by Worthington Steel, Inc. (NYSE: WS), with Baosteel Tailored Blanks as the minority partner.
