SAS PORTEJOIE

What SAS PORTEJOIE does

SAS Portejoie is a French artisanal metalworking, locksmithing, and industrial piping company headquartered at 49 rue Maurice Paillot, Froncles (Haute-Marne, 52), founded in 1979 by Monsieur Portejoie. The company designs, fabricates, installs, and maintains custom metal structures and piping systems in steel, aluminum, PVC, stainless steel, and copper for individual homeowners and professional clients (industries, local authorities, agri-food, commerce, construction) within roughly a 50 kilometer radius of Froncles covering towns such as Chaumont, Andelot-Blancheville, and Joinville. Its offering is organized around four service lines: serrurerie (locksmithing including emergency callouts), métallerie industrielle (industrial metalwork such as platforms, railings, barriers, gates, and structural reinforcements), tuyauterie industrielle (industrial piping study, fabrication, and repair), and fournitures industrielles (retail sale of hardware, fasteners, plumbing, electrical, PPE, steel by the meter, paints, and tools with 24–48 hour delivery or in-store pickup).

Since 2021, SAS Portejoie has been wholly owned by the holding company Mikindus, alongside sister firm ERED, which specializes in lifting equipment and overhead cranes. Within the Mikindus group, Portejoie plays a complementary role as the captive fabricator of the metal structures required for ERED's lifting operations, creating an integrated manufacturing ecosystem. The business operates on a project-based, quote-driven model with no publicly disclosed pricing or revenue; customer acquisition relies on direct phone contact, a website contact form, a photo gallery showcasing completed projects, a minimally active Facebook page, and word-of-mouth referrals within its local service area. The company has approximately 6 employees and operates as a private SAS (simplified joint-stock company) registered in France, with Mickael Riche serving as Directeur de la publication.

Direct peers

• Spie: Spie is a major French independent industrial services group offering metalwork, piping, and maintenance to industrial clients. It mirrors Portejoie's industrial metalwork and piping services at a vastly larger scale, making it a direct functional peer for industrial-side work.
• SNEF: SNEF is a French industrial services company with electrical, mechanical, and metalwork capabilities serving industries and local authorities. Its industrial-services profile, including piping-adjacent work, parallels Portejoie's professional-services model.
• Engie Solutions (Endel): Engie Solutions, which includes the legacy Endel industrial-services brand, delivers industrial piping, mechanical maintenance, and metalwork across France. It is the closest large-scale peer for Portejoie's tuyauterie industrielle and maintenance offering.

Broad incumbents

• Fichet: Fichet is a long-established French manufacturer of security doors, armored doors, and locks. It competes with Portejoie's serrurerie and portes blindées lines at a brand-led, national scale rather than local fabrication.
• Bouygues Construction: Bouygues Construction is a major French building contractor with metalwork and structural-steel activities. It is comparable as a broad incumbent that can absorb the types of structural metal projects Portejoie serves at industrial sites.
• Tryba: Tryba is a French network-manufacturer of windows, doors, and verandas, distributed through local installers. Its franchise model directly competes with Portejoie's residential fenêtre, porte, and pergola offerings in similar customer segments.
• Technal: Technal is a major French manufacturer of aluminium windows, doors, and façade systems used in residential and commercial projects. It is comparable to Portejoie's fenêtres, baies vitrées, and garde-corps in aluminium, but operates as an industrial brand rather than a local installer.
• Bricard: Bricard is a leading French lock and security-hardware brand (part of Assa Abloy). It overlaps with Portejoie's locksmithing/security-closures offering at the hardware-product level rather than at the local service-installation level.
• VINCI Construction: VINCI Construction delivers large-scale building and infrastructure projects in France, with in-house metalwork and structural-steel capabilities. It overlaps with Portejoie's industrial and structural metalwork from a much broader platform perspective.
• Eiffage Construction (incl. Eiffage Métallique): Eiffage operates a large construction and metalwork division (Eiffage Métallique / Construction Métallique) producing structural steel, railings, and metal façades. It competes for the same industrial metalwork projects as Portejoie but as part of a much broader portfolio.
