AdC-Accessoires de Construction

What AdC-Accessoires de Construction does

AdC-Accessoires de Construction (AdC-SAS) is a French B2B manufacturer and distributor of construction accessories, founded in January 2008 as the French operating subsidiary of Bavarian steel roller Stahlwerk Annahütte (SAH), which has been part of the Max Aicher steel group since 1975. From its headquarters at Le Thillay (Île-de-France) — anchored by a 7,000 m² workshop where 12-meter threaded bars are cut to specification — and a southern France depot opened at Genas in April 2014, AdC services three primary construction-industry customer segments: foundation and special civil engineering works companies (geotechnical and prestressing bar applications), prefabrication plants (lifting and fixation systems for precast concrete elements), and on-site construction operations (formwork rods and accessories).

The product portfolio spans 271 SKUs across six categories: lifting accessories, formwork bars and accessories, geotechnical/prestressing bars (including the SAS500, SAS670, and SAS950 systems manufactured in Germany), consumable accessories, fixation systems (anchor rails, sockets, Coque de serrage clamping shells), and magnetization products (notably the patented MagFly universal and AP magnets). The portfolio is split across two sub-brands: SAS SYSTEMS, comprising SAH-produced threaded bars certified by AFCAB and European technical approval bodies, and ADC SYSTEMS, comprising accessories engineered by AdC's in-house French design office. Exclusive French distribution rights for German formwork specialist BT Innovation GmbH, signed in May 2021, extend the catalog into MagFly AP and MultiForm lines.

AdC operates a direct enterprise field-sales model targeting B2B customers through its own sales force, supported by a dedicated Belgium sales representative and recurring presence at French and European construction trade shows (Intermat, Solscope, Techni-Mat). Pricing is quote-based rather than publicly listed, with sales driven largely by the breadth of certified offering, custom cutting service, and stocking depth. The company's competitive position is reinforced by ISO9001/14001/50001 certifications at the parent level, AFCAB and European technical approvals on core bar systems, and a January 2025 EcoVadis Silver Medal. No public revenue, headcount-growth data, or external funding events are disclosed in available sources.
