STI France Company

What STI France Company does

STI France (SAS STI France) is a French aerospace surface treatment and finishing company, wholly owned by the global STI-GROUP. Headquartered at 7 Rue Galilée in Paris with manufacturing operations at four production sites — Arudy, Saint-Martin-de-Seignanx, and PRODEC METAL in France plus SURTIP in Agueda, Portugal — the company delivers specialized chemical, mechanical, and decorative surface treatments along with non-destructive testing (NDT) for aerospace components and luxury applications. The core technical portfolio includes more than 40 special processes and over 100 qualifications from major aerospace primes, covering steels, aluminum (including REACH-compliant TSA anodization), composites, and decorative substrates such as precious metal deposition, polishing, and decorative chrome.

The company serves approximately 500 clients including 15 major aerospace prime contractors — Airbus, Boeing, Safran, Thales, Dassault Aviation, Bombardier, Embraer, Stelia Aerospace, JetAviation, and AMAC Aerospace — alongside luxury interior, automotive, nautical, and leather goods customers reached through the PRODEC METAL subsidiary. Certifications include NADCAP, EN 9100, and ISO 9001, with REACH-compliant chemistry positioning the firm for tightening European environmental regulation. Services are sold on a project-based, multi-year contract model under direct enterprise sales relationships, with quote-based pricing and a stated 48-hour inquiry response commitment.

STI France generates revenue from professional services delivered across its site network, with no public pricing, recurring software, or marketplace monetization. The go-to-market motion is direct enterprise sales to aerospace OEMs and tier-1 suppliers, supported by a website, LinkedIn, Instagram, and email newsletter presence. Approximately 180 collaborators deliver across the four sites. Growth has been driven by a combination of acquisitions (Avia Peinture 2011, PRODEC METAL 2015) and organic capacity additions (Saint-Martin-de-Seignanx 2011, PRODEC METAL Arudy 2021, SURTIP Portugal 2022).

Direct peers

• Aalberts Surface Technologies: European-headquartered division of Aalberts N.V. offering heat treatment, surface treatment, and coatings to aerospace and industrial customers; competes with STI France for tier-1 aerospace special-process work across continental Europe.
• Socomore: French-headquartered aerospace surface treatment and chemical solutions specialist serving Airbus, Boeing, and Safran with proprietary qualified processes — a direct European competitor to STI France in pre-treatment, surface preparation, and finishing.
• ASB Industries: US-based aerospace surface treatment provider specializing in thermal spray coatings, shot peening, and special processes for OEM and MRO customers — overlapping with STI France's special-process and finishing capabilities.
• Curtiss-Wright (Surface Technologies division): Provides specialized coatings, surface treatments, and shot peening for aerospace and defense components, with a global network of treatment facilities directly comparable in capability and customer profile to STI France.

Broad incumbents

• Howmet Aerospace: Aerospace engine and structures supplier with significant in-house surface treatment and coatings capabilities for turbine and airframe components — a large incumbent that overlaps STI's functional coating scope for prime-engine customers.
• Praxair Surface Technologies (Linde): Part of Linde plc, offers thermal spray coatings, wear-resistant coatings, and aerospace surface treatments as part of a much larger industrial gases and engineering portfolio — broad incumbent with overlapping aerospace capabilities.
• Bodycote: Global surface treatment specialist offering hot isostatic pressing, brazing, and coatings across aerospace, automotive, and industrial markets. Overlaps with STI France on aerospace component surface treatments but serves a much broader industrial customer base.
• Lufthansa Technik: One of the world's largest independent MRO providers, with bundled component services including surface treatment, painting, and NDT — competes with STI France for aftermarket treatment work at airlines and completions centers.
• Henkel (Loctite / Surface Treatment): Global specialty chemicals group with aerospace-adjacent surface treatment, bonding, and coating technologies through its Adhesive Technologies division — overlaps with STI on functional surface chemistry at a much larger scale.

Regional players

• Nihon Parkerizing: Asia-Pacific market leader in surface treatment chemicals and services for automotive and industrial customers; serves as a regional analog in scale and process breadth rather than a direct Western competitor.
