Corrosia

What Corrosia does

Corrosia is a France-based B2B professional services firm specializing in corrosion management, inspection, technical assistance, and on-site expertise for metal structures. Founded in 2014 and headquartered in Roubaix, the company serves project owners (Maîtres d'ouvrage) and project managers (Maîtres d'œuvres) across infrastructure, energy, naval, nuclear, and industrial sectors. Its service portfolio is built around four core offerings: technical assistance across the construction lifecycle, third-party inspection and fabrication follow-up, on-site expertise including damage mapping and restoration recommendations, and DGAC-certified drone-based aerial imaging. Corrosia holds a dense credential stack (FROSIO, NACE, ACQPA, ISO 9001, ASME, MASE, IIW, AMPP, CEFRACOR, Cofrend) and applies NORSOK M-501 standards for offshore-grade protective coating systems, which collectively act as a hard entry barrier in regulated inspection markets.

The firm's technology core combines certified human expertise with a computer-vision-based AI system for automatic corrosion and defect detection, developed in partnership with Weaverize and recognized as a laureate of the Cerema "Ponts Connectés" program under the France Relance plan in April 2021. The system ingests drone imagery to identify, quantify, and classify defects on bridges and other structures, providing a data flywheel for improving accuracy as inspection volume grows. Corrosia has also deployed an AI-powered chatbot and an online training module (Formation en ligne) to extend its service surface.

Commercially, Corrosia operates a hybrid model: project-based professional services billed via direct technical proposals to enterprise and government clients, complemented by a tiered subscription membership (Espace Membre) ranging from Free to €199/month (Gold). The company sells through an enterprise field-sales motion, primarily direct to project owners and project managers, and operates in France, Belgium, Spain, the Netherlands, and the UK. Since January 2023, Corrosia has been a wholly-owned subsidiary of Groupe Institut de Soudure (ISGroupe), retaining its brand identity and leadership under President Victor Rodriguez while gaining access to the parent group's welding and structural engineering network. Notable reference customers include SNCF, TotalEnergies, Engie Green, TechnipFMC, Veolia, Groupe ADP, Ministère des Armées, Voies Navigables de France, and multiple French departments and municipalities.

• Apave: Major French TIC (testing, inspection, certification) firm offering corrosion, structural, and industrial asset inspection services to similar regulated clients in France. Closely overlaps Corrosia's customer verticals and inspection portfolio.

Broad incumbents

• Hempel: Global coatings manufacturer specializing in protective and marine coatings, including NORSOK-compliant systems. Adjacent to Corrosia's coating inspection expertise but operating on the products side rather than inspection services.
• TÜV Rheinland: German-headquartered global TIC firm with industrial services and asset integrity inspections relevant to Corrosia's corrosion management work, particularly for cross-border European enterprise clients.
• SGS: Global inspection, verification, testing, and certification company with corrosion and asset integrity practices serving oil & gas, infrastructure, and industrial clients worldwide. Overlaps with Corrosia on offshore and energy inspection work.
• Bureau Veritas: Global TIC leader with extensive corrosion, asset integrity, and industrial inspection services across energy, marine, and infrastructure. Competes with Corrosia on large multi-disciplinary tenders but serves a much broader portfolio.
• Jotun: Norwegian coatings manufacturer with strong offshore, marine, and protective coatings portfolio. Comparable expertise in NORSOK M-501 systems and serves the same energy/marine customer base as Corrosia, but on the supply side.
• DEKRA: Global TIC organization offering industrial inspection, material testing, and corrosion-related services. Comparable at the service-line level though much larger in scale and geographic reach than Corrosia.

Others

• Groupe Institut de Soudure: Parent company of Corrosia since January 2023, providing welding expertise and industrial services across France and Europe. Internally adjacent rather than competitive, but its welding and structural inspection offerings overlap the same technical and customer base.

Emerging players

• FlyPix AI: Aerial inspection and AI analytics platform applying computer vision to infrastructure, asset, and environmental inspection. Comparable to Corrosia's drone-plus-AI approach for bridge and structural defect detection, though targeting a broader set of verticals.
