Tammet

What Tammet does

Tammet Oy is a Finnish manufacturer of metal mesh and safety solutions headquartered in Tammisaari (Ekenäs), Finland. Founded in 1948, the company produces a broad portfolio of welded mesh, expanded metal (streckmetall), woven mesh, gabion systems, architectural mesh, and construction-site safety products manufactured from hot-dip galvanized steel, stainless steel, aluminum, marine-grade aluminum, Corten (weathering steel), copper, and brass. Operations are organized across five end-market verticals: Construction and Infrastructure, Construction Site Safety, Architecture and Design, Specialized Industry, and Defence and Protection, with a dedicated sub-brand, Tammet Art & Design, addressing architectural applications.

The company operates from a single integrated facility in Tammisaari that combines a prototype workshop for custom development, a 6,000-item warehouse for standard SKUs, and 30 product groups spanning both standardized and engineered solutions. Notable proprietary or co-developed offerings include the Tammet-ViaCon modular F-panel gabion retaining wall system, EN 13374-compliant edge protection systems with C4-M to C5-H corrosion ratings and RAL powder coating, and a Drone Protection Fencing line for counter-UAS physical protection. In 2025, Tammet became the first gabion manufacturer in Finland to receive an Environmental Product Declaration (EPD), providing independently verified lifecycle environmental data for sustainable construction procurement. The company is ISO 9001 certified.

Revenue is generated primarily through direct B2B project-based sales to enterprise, government, and institutional buyers across the Nordic region and broader Europe, supplemented by White Label manufacturing, Custom Solutions prototyping, and Planning Services for technical design. Approximately 75% of revenue is derived from exports, and the sales organization is structured by geography (Norden; Europe & World). Named customers span construction, government infrastructure, energy, museums, retail, and education — including NCC, JKMM Architects, Fortum, the Finnish Transport Infrastructure Agency (Väylävirasto), the Swedish Transport Administration (Trafikverket), and the Estonian National Museum — indicating genuine cross-sector diversification of the order book.
