Lambrechts

What Lambrechts does

Lambrechts, legally Sax, Lambrechts & Schrauwen and trading as STG, is a Belgian private wholesaler founded in 1946 and headquartered in Genk that distributes sanitary, HVAC, renewable-energy, wellness, tile, and installation-material products to professional installers and consumers in Belgium. The company operates a multi-channel platform combining a physical ProShop network positioned within 15 minutes' drive of customers, a dedicated B2B e-commerce webshop (stg-pro.be) with 20,000+ articles, a separate B2C platform (stg-badkamers.be), Click & Collect and Nachtkluis (Night Locker) pickup services, and a centralized project coordination offering for residential and non-residential construction projects. Underlying infrastructure includes 12,000+ stocked items supporting next-day delivery on orders placed before 8 PM, and the STG ProClub loyalty program with 3,463 enrolled professional installers.

The business model is primarily transactional product resale across multiple categories, supplemented by fee-based project coordination and installation services (notably underfloor heating) for residential and commercial developers. Revenue mechanics rest on volume distribution to a fragmented trade base rather than named enterprise contracts; pricing is quote-based for projects and account-based for ProClub members, and is not publicly disclosed. Recent strategic activity in 2025-2026 has focused on assortment expansion (new launches from Henco, Begetube, ProOne, Procasa, hansgrohe, Vuerto, Watergenius, Grundfos), an exclusive hansgrohe partnership, extension of project coordination into non-residential construction, and continued investment in the EXPO26 industry event. The company is privately held with no disclosed venture capital, private equity, or institutional ownership.

Direct peers

• Cedeo (Saint-Gobain Distribution): French sanitary/HVAC/heating distributor serving professional installers with physical branches, e-commerce, and project services. Highly comparable business model to STG: trade-loyalty oriented, branch network within short driving distance, similar product mix.
• IDO Installateursbedrijven: European installer-focused sanitary/HVAC distribution network with physical branches and installer loyalty programs. Operates similar multi-country installer supply model in Benelux-adjacent markets.
• Van Marcke: Belgian wholesaler of sanitary, HVAC, and installation materials serving both professional installers and consumers through physical showrooms and digital channels. Direct competitor to STG in the Belgian installer market with overlapping product lines (sanitary, HVAC, tiles) and similar multi-channel go-to-market.
• Facq: Belgian distributor of sanitary, heating, and installation products primarily to professional installers via ProShops and online ordering. Operates a near-identical installer-loyalty and proximity-based distribution model in Belgium/Flanders.

Others

• Grundfos (manufacturer-side reference): Global manufacturer of pumps and water solutions distributed through STG (UNILIFT range). Not a competitor but a supplier partner; included as an ecosystem comparable representing the upstream vendor relationship that defines product availability and exclusivity dynamics.

Broad incumbents

• Rexel: Listed global distributor of electrical, lighting, HVAC, and renewable-energy products to professional installers. Larger incumbent with broader product portfolio but overlapping installer customer base and similar channel-partner motion.
• Sonepar: Global B2B electrical and HVAC distribution leader serving installers and industrial customers. Adjacent category overlap with STG in HVAC components and the same channel-partner sales motion, though primarily electrical-skewed.
• Travis Perkins: UK-listed building materials and installer-focused distribution group with branch network, loyalty schemes (e.g., TradePoint), and mixed B2B/B2C model. Comparable scale and installer-channel centricity in a different geography.
• Saint-Gobain Distribution Solutions Belgium: Belgian arm of Saint-Gobain's distribution division covering building products, sanitary, and installation materials to professional clients. Larger incumbent competing in the same installer/B2B channel with broader product portfolio.

Regional players

• Brico Depot: Belgian DIY and home improvement chain serving both consumers and trade professionals with sanitary, tiles, and installation materials. Overlaps with STG's residential tile and sanitary assortment but skews more B2C/DIY.
