Decayeux

What Decayeux does

Decayeux is a French family-owned industrial group founded in 1872 in Feuquières-en-Vimeu (Picardy) by brothers Antoine and Désiré Decayeux, manufacturing mailboxes, parcel boxes, armored entry and sliding hall doors, high-security cylinders and master-key organigram systems, and urban furniture for the European market. The group positions itself as the leading European mailbox manufacturer, having introduced the first metal mailbox to the market, and operates wholly-owned subsidiary brands CARMINE, GENIFER, and QUESDEVILLE for cylinder and lock manufacturing. Its customer base spans individual homeowners, residential property managers and housing cooperatives, building contractors and architects, and institutional buyers in government, hospitality, and healthcare.

The product portfolio spans five core lines: standardized mailboxes (individual and collective), connected and autonomous parcel boxes (mycolisbox®, my-securebox), armored and sliding hall doors (PortAdapte®), high-security cylinders and organigram systems, and urban furniture. The smart-building portfolio centers on the Walter App ecosystem, integrating parcel boxes, digital displays (MyBoard), e-paper name tags (MyTag), and smart access control (MyRingBell) into a connected concierge service. Technical differentiation rests on Colislock® dual-lock parcel security, the TARA protected cylinder profile with 722,000 key variations and A2P-certified intrusion resistance, and PMR-accessibility compliant PortAdapte® doors. The group holds ISO 9001:2015, A2P, VDS, EN 1303, and Exova Certisecure certifications, runs 100% of manufacturing from Picardy on renewable electricity, and is a signatory of the UN Global Compact since 2009.

Decayeux monetizes through unit-priced hardware sales (mailboxes, doors, cylinders, locks, urban furniture) with lead times ranging from two to six weeks, sold primarily through direct field sales to contractors, architects, and property managers. A 3D online configurator at la-boite-aux-lettres.com enables professionals to design, quote, and order collective mailbox blocks; a Paris-region showroom opened in 2024 to deepen specifier engagement. Distribution is supported by a partner network and an authorized key-reproduction channel via Soluclef. The company remains privately held with no public listing, has received outside growth capital including a 2015 round led by Développement et Partenariat (≈€4.77M) following an earlier 2012 Picardie Investissement commitment, and is currently led by Stéphane Decayeux as Directeur Général.
