Inspired by the idea, Raigo soon traveled to Switzerland for training at a company manufacturing steel profiles. Becoming familiar with these profiles laid the foundation for the idea of establishing Tammer O\u00dc.<\/p>\n\n\n\n<p>Over 30 years of operation, Tammer has grown into the largest manufacturer of project-based metal doors in the Baltic and Nordic regions. This Estonian capital-based family business has expanded its production facilities to 15,000 m\u00b2 and today provides employment to more than 300 specialists on a daily basis.<\/p>\n\n\n\n<p>Tammer focuses on manufacturing durable, sustainable, and safety-enhancing project-based metal doors and other steel joinery solutions designed to perform in various risk situations. Under the Tammer brand, more than 36,000 doors are produced annually for both the construction and marine sectors, and the company\u2019s annual turnover exceeds 38 million euros.
