Salzgitter Flachstahl GmbH

What Salzgitter Flachstahl GmbH does

Salzgitter Flachstahl GmbH is a privately held German integrated steel mill and the largest steel subsidiary of Salzgitter AG, headquartered at Eisenhüttenstraße 99 in Salzgitter, Lower Saxony. The company operates a single-site integrated mill with approximately 4.7 million tons of annual crude steel capacity and a workforce of around 6,000, producing flat steel products in thicknesses from 0.4 to 25 mm and widths up to 2,000 mm. Its portfolio spans hot-rolled wide strip, cold-rolled fine sheet, hot-dip galvanized products, electrolytically galvanized products, and organically coated products, marketed under registered brands including RobuSal®, AcaSal®, Pretex® focar®, StronSal® MC, seca®/seca®xtra, xpand®, and FolaSal®.

The company runs a B2B direct sales motion organized into specialized departments for automotive OEMs and suppliers, trade and service centers, cold rollers, and construction/household appliances/end consumers/pipe customers, supported by an eService platform, EDI integration, and COMDaS-Online for technical material data. Customer segments span the automotive industry (primary), pipe and tube manufacturers, cold rollers, construction, and trade/service centers. Named enterprise customers include Volvo Cars (ScanLoop closed-loop partnership for recycling end-of-life vehicles), CNT Bau/Casais-Gruppe (~50,000 tons of pipe slab for the Angola Quilonga Grande water project), ONTRAS Gastransport GmbH (hydrogen core network pipes), and intra-group partners Mannesmann Grossrohr and Mannesmann Line Pipe.

Salzgitter Flachstahl is mid-transformation under the SALCOS® (Salzgitter Low CO2 Steelmaking) program, which includes a 100-MW electrolysis plant for green hydrogen and produces commercially available SALCOS® Grünstahl (green steel) products. Complementary circular-economy initiatives include the ScanLoop closed-loop partnership with Volvo Cars and the KLASSE consortium project for recovering valuable metals from steel mill slag. Revenue mechanics are quote-based B2B sales of physical steel tonnage; pricing is not publicly disclosed. The company is actively operating with no disclosed revenue figures in the source data, and growth is being driven by sustainability-differentiated products, hydrogen-infrastructure demand, and selective international infrastructure contracts.
