„A wall divides, a door connects“

– Tammer OÜ

By the beginning of 2020, Tammer has become the largest metal door manufacturer in the Baltics, whose cooperation partners are shipyards, construction companies, real estate maintenance companies, and door manufacturers in the Baltic and Nordic countries. Exports account for more than 80% of production.

The idea to create a door factory began in 1995, on the ferry Georg Ots, where two complete strangers decided to share an order of pizza. Just a few months later, Raigo Tammo, the father of a large family of 6 and an entrepreneur, founded the family business Tammer, which has grown into the largest manufacturer of metal opening fillings in the Baltics under the leadership of his son Anti. 

Tammer’s goal

Tammer’s mission

Tammer is a member of the Association of Construction Material Producers of Estonia and the International Chamber of Commerce ICC WBO.  

Tammer is a recipient of the Family Enterprise of the Year award of 2019. In 2019, Tammer was recognized as a silver level family-friendly employer and as a bronze level Responsible Business Index company. In co-operation with the Estonian Rescue Board, a campaign “Safe Christmas” is organized every year, within the framework of which one child care institution is gifted proper opening fillings.
