After extensive collaboration, product development, and numerous tests, we have launched a brand-new product together with A Lundgren Smide AB: the SMU113 Cell Door.

The product is suitable for both indoor and outdoor use in various high-security facilities such as psychiatric hospitals, prisons, detention centers, and more. Cell door meets EI₂60 fire resistance requirements, offers burglary resistance up to RC4, and provides sound insulation of up to 39 dB.
Together with Lundgren Smide, we are also delivering the first project featuring these brand-new products to a detention facility in Sweden. In total, Tammer will supply over 1,400 products to the object, the majority of which are steel profile doors.
Tammer and Lundgren have been cooperating for an impressive 20 years, with the last 5 years specifically focused on various prison projects. We believe that our long-term partnership has developed into a highly effective collaboration.
Tammer’s Head of Scandinavian Sales and Project Department, Tõnis Larven, says: “In prison projects, we have a strong understanding of each other’s expectations, which allows projects to progress smoothly and efficiently. Lundgren is also a highly solution-oriented partner, enabling us to solve emerging challenges together quickly and effectively.”
Lundgren Smide is also very proud of the long cooperation between the companies in matters like this and other opportunities and projects. The company is today one of Sweden’s leading suppliers of cell doors and security doors for prisons, alongside their regular steelworks production.
Tammer supplies the SMU113 cell door to projects across Scandinavia, the Baltics, the rest of Europe, and other international export markets. For Swedish projects the official distributor of the SMU113 cell door product is A Lundgren Smide AB.
