What Prestia Group does

Prestia Group is a French industrial services company specializing in anti-corrosion treatment of steel, founded in 1978 in La Chapelle Caro (Morbihan) and operating as a subsidiary of the Dutch conglomerate Roto Group (Roto B.V., Uitgeest). The group runs seven interconnected production sites across the Grand Ouest region of France (Bretagne and Normandie), with its flagship PRESTIA SBG facility housing the largest hot-dip galvanization bath in France at 16.5 meters in length. Headcount stood at approximately 475 employees as of 2019.

The group's core technical offering spans four treatment modalities: hot-dip galvanization (immersion in a zinc bath at approximately 450°C), metallization (zinc thermal projection for parts too large or complex for immersion), powder coating or thermolaquage (electrostatic powder application with oven polymerization), and liquid paint. These can be delivered standalone or combined in the proprietary Duplex system, which layers zinc protection with powder coating in three finish tiers (Indus, Estheth, Artec) plus offshore and Protec'Sea variants for extreme marine environments. Service differentiation rests on the scale of the SBG bath, the in-house logistics fleet for pickup and delivery, and a dense certification stack including ISO 9001, ISO 14001, ISO 45001, Qualisteelcoat, and ACQPA.

Prestia generates revenue through project-based, quote-driven pricing across all services, billed per batch with prices varying by part dimensions, weight, surface area, color complexity, and corrosive category. Go-to-market is direct enterprise field sales targeting metal construction firms, public and private infrastructure projects, industrial serial manufacturers, and PME/TPE metalworkers, with a segmentation approach tailored to each vertical. The group also pursues geographic and capability expansion through acquisitions (LMPI in 2014 for liquid paint, A2PR in 2019 for Normandie footprint) and ecosystem partnerships with powder coating manufacturers (Axalta, Akzo Nobel, IGP) and industry associations (Galvazinc, EGGA, AFTAP). No public revenue disclosure is available.

Revenue model

1. Hot-Dip Galvanization Services: Core revenue stream from hot-dip galvanization of steel components. Priced depart factory with transport options. Revenue is project-based per batch of parts treated, with pricing varying by part dimensions, weight, and corrosive category required.
2. Thermolaquage (Powder Coating): Powder coating (thermolaquage) on raw or galvanized steel. Offered as standalone service or as part of Duplex system. Provides aesthetic finishing with over 8,000 RAL color options. Revenue per batch based on surface area and color complexity.
3. Metallization Services: Zinc thermal projection (metallization) for large or complex-shaped parts that cannot be immersed. Often combined with powder coating as Duplex. Project-based pricing per treatment area.
4. Liquid Paint / Laquage: Liquid paint application (laquage) in workshop and on-site, including ACQPA-certified systems for high-durability requirements (offshore, naval, industrial). Per-batch project pricing.
5. Ancillary Services (Logistics, Consulting, Certification): Pickup and delivery logistics, design-for-galvanization consulting, FROSIO inspection, certification (galvanization certificates, control PV reports), passivation, drilling, assembly, packaging, repair kits, and asbestos/lead removal. These generate additional per-service revenue.

Broad incumbents

• Jotun: Norwegian global paints and coatings manufacturer with a strong protective coatings portfolio for offshore, marine, and infrastructure. Comparable through its participation in anti-corrosion specification ecosystems (NORSOK, ISO 12944 CX class) where Prestia holds ACQPA-accredited applicator status.
• ArcelorMittal: World's largest steel producer with downstream coated products (Galvalume, galvannealed) that overlap with the protective-coating use cases Prestia serves in construction and infrastructure. Operates broadly rather than as a specialist service provider.
• PPG Industries: Global industrial coatings supplier serving construction, infrastructure, and marine markets with protective coating systems. Comparable because it sells into and competes with Prestia's liquid paint and powder coating applications through similar specification channels (ACQPA, ISO 12944).
• Sherwin-Williams (Protective & Marine): Global coatings manufacturer with a dedicated Protective & Marine division serving bridge, energy, and infrastructure end markets. Comparable through its specification-driven selling motion in the same corrosion-protection tender ecosystem Prestia serves.
• Voestalpine AG: Austrian integrated steel and steel processing group with surface treatment operations across Europe. Although primarily a steel producer, voestalpine competes in metal finishing and coated steel products serving similar construction and infrastructure end markets.

Others

• Roto Group (Parent): Dutch diversified industrial conglomerate that owns Prestia and other surface treatment businesses across Europe. Comparable as the umbrella entity whose portfolio strategy (M&A, geographic expansion, capital allocation) directly shapes Prestia's growth path.
• AkzoNobel: Global paints and coatings manufacturer whose Polyzinc brand is applied by Prestia. As a key supplier in the value chain, AkzoNobel is comparable because it sells complementary powder coating chemistry into the same anti-corrosion specification ecosystem and sets standards Prestia's certified applicators must meet.
• EGGA (European General Galvanizers Association): European industry association for hot-dip galvanizers in which Prestia is a member. Comparable as the industry body that sets common standards, provides training, and influences regulatory positions that affect Prestia's competitive positioning.

Direct peers

• Fontaine Galva: French regional hot-dip galvanizing service provider. Comparable because it offers the same core service (hot-dip galvanization of fabricated steel parts) to metalworking and construction clients, with smaller bath dimensions and a regional footprint overlapping parts of France.
• Galva Union: French hot-dip galvanizing services group operating multiple production sites across France. Direct competitor in the same service category, offering galvanization for steel fabricators and infrastructure clients with comparable bath dimensions and regional coverage.
