Gamma Home Improvement and Building Supplies

Gamma is a prominent hardware store chain operating in the Benelux region, specializing in DIY (Do-It-Yourself) building materials, tools, and home improvement products. Established in the Netherlands in 1971, it became a pioneer in the franchise-based hardware market, offering a wide range of goods from heavy construction materials to decorative home finishes.

While Gamma sells many third-party brands, its private-label products are sourced globally, with manufacturing occurring in multiple countries depending on the product line. Many timber and heavy building materials are sourced regionally within Europe, while hand tools and smaller hardware accessories are often produced in manufacturing hubs in Asia.

Gamma is owned by Intergamma B.V., a franchise organization headquartered in Leusden, Netherlands. Intergamma operates as a cooperative venture, meaning the brand remains firmly under Dutch ownership. It manages both the Gamma and Karwei brands, maintaining a dominant market share in the Dutch and Belgian home improvement sectors.
