DEG Dach-Fassade-Holz eG

What DEG Dach-Fassade-Holz eG does

DEX eG (formerly DEG Dach-Fassade-Holz eG) is a German purchasing cooperative (eingetragene Genossenschaft) headquartered in Hamm, Germany, with an additional administrative office in Weyhe. The company operates as a wholesale distributor of building materials specializing in roofing, façade, and wood (Dach-Fassade-Holz), its predecessor dating to 1947. The cooperative serves professional roofers (Dachdecker), carpenters (Zimmerer), and specialist trade businesses (Fachbetriebe) through 33 regional branches across North Rhine-Westphalia, Lower Saxony, Bremen, Hesse, and Thuringia, with direct delivery to construction sites and an online ordering platform (OBIS).

The company's product portfolio spans eleven core categories—daylighting, fasteners and consumables, façade systems, flat roof and insulation, wood, machines and tools, metals and drainage, photovoltaics, smoke and heat exhaust systems, pitched roof, and trapezoidal sheet/hall construction—complemented by value-added services including precision façade panel cutting (Münster and Weyhe), custom metal forming, a wood and timber framing service (Abbundservice), measurement support, a maintenance and workshop service, and a regular small-materials delivery service (12er Service). Technology is operational rather than transformational: digital procurement is enabled through OBIS, supported by in-house processing facilities that deliver custom-fabricated components.

DEX eG operates as a member-owned purchasing cooperative, meaning members are simultaneously customers and owners with co-determination rights, profit participation, and access to exclusive events. Revenue is generated from margins on products sold to members and affiliated trade businesses, leveraging collective purchasing power through the ZEDACH eG network (Zentralgenossenschaft des Dachdeckerhandwerks). The current entity was formed in August 2024 through the merger of DEG Dach-Fassade-Holz eG and DENW, unifying two traditional cooperatives under the DEX eG brand. The company employs 501-1,000 people and does not publicly disclose revenue.
