Nassau Sectional Doors

NASSAU Door is a well-known Danish manufacturer specializing in high-quality sectional overhead doors for industrial, commercial, and residential applications.

Founded in 1970 in Denmark, NASSAU built its reputation on Danish engineering, durability, and energy-efficient insulated door panels. Headquartered with production facilities in Ringe on the island of Funen, the brand has grown across Europe through dedicated sales and service subsidiaries.

In 2016, NASSAU Door A/S was acquired by the multinational Swedish access solutions group ASSA ABLOY, operating within its ASSA ABLOY Entrance Systems division. While other distinct entities share the geographic name 'Nassau' (such as international locations, banks, or golf balls), NASSAU in Denmark is renowned for overhead doors.
