ETEM

ETEM is a Greek aluminium extrusion and architectural-systems company headquartered in Athens. Established in 1971 under the name Company of Light Metals, it became one of Greece's early specialist producers of integrated aluminium systems for construction. Its activities span the design and manufacture of aluminium profiles for architectural projects and industrial uses, linking materials production with building-envelope engineering. The company is associated with the development of Greece's early modern aluminium architecture. It designed and produced integrated architectural aluminium systems and was involved in the first curtain wall installed on a high-rise building in Greece, the Athens Tower, during the 1970s. This heritage places ETEM among the companies that helped introduce curtain-wall construction and more system-oriented aluminium building products to the Greek market. ETEM's principal output is extruded aluminium profiles. These profiles can be developed into systems for façades, curtain walls, windows, doors, shading, and other architectural applications, as well as components for industrial customers. Its production unit in Magoula, Attica, has reported total capacity of more than 15,000 tonnes per year. In addition to manufacturing in Greece, ETEM has maintained commercial activity through subsidiaries or affiliated operations in Bulgaria, Romania, Serbia, and Ukraine, giving it a regional presence in southeastern and eastern Europe. A strategic cooperation agreement between ETEM and Cosmos Aluminium was signed in December 2022. The arrangement was completed in 2023 through a merger by absorption, after which ETEM became part of the Cosmos Aluminium Group. The combination brought together Cosmos Aluminium's aluminium-extrusion capabilities and ETEM's architectural-systems expertise. It strengthened the group's ability to address both international aluminium markets and specialized building-system applications. ETEM is therefore best understood as an industrial and architectural-products brand rather than a consumer-facing aluminium label. Its market proposition rests on technical design, extrusion manufacturing, integrated systems, project support, and regional distribution. Publicly available reference material identifies its principal facilities, historical architectural contribution, production capacity, international commercial footprint, and integration into Cosmos Aluminium, but does not provide sufficient information for a detailed account of current executives, revenue, ownership percentages, or a standalone post-merger corporate structure.

ETEM was founded in Greece in 1971 as the Company of Light Metals. From its early years, the company concentrated on aluminium extrusion and on the development of systems that could be used in architectural construction. Its role was not limited to supplying raw or semi-finished aluminium; it worked on integrated profiles and assemblies intended to perform as parts of a building envelope. The company became associated with the modernization of Greek construction through its work on architectural aluminium systems. During the 1970s, ETEM was responsible for the first curtain wall on a high-rise building in Greece, the Athens Tower. Curtain walls use a lightweight external envelope, typically supported independently from the main structural frame, and their adoption marked an important development in high-rise construction. ETEM's participation reflected the growing use of engineered aluminium systems in Greek commercial and urban architecture. Over time, ETEM expanded its industrial and architectural production activities. Its core manufacturing remained aluminium extrusion, a process in which heated aluminium billets are forced through dies to create profiles with defined cross-sections. These profiles can then be fabricated or assembled into systems for façades, curtain walls, windows, doors, shading devices, and other construction applications. The company also served industrial customers requiring profile-based aluminium components. Its production facility at Magoula in Attica has a stated total capacity of more than 15,000 tonnes per year. ETEM developed a regional commercial presence beyond Greece. Reference material identifies significant activity through subsidiaries in Bulgaria, Romania, Serbia, and Ukraine. This network supported the sale and distribution of architectural and industrial aluminium products in several southeastern and eastern European markets, although the available material does not specify the individual subsidiary names, incorporation dates, or current operating structures. The next major stage in ETEM's corporate history came through its relationship with Cosmos Aluminium. The two companies signed a strategic cooperation agreement in December 2022. The cooperation was completed in 2023 through a merger by absorption, making ETEM part of the Cosmos Aluminium Group. The combination joined Cosmos Aluminium's aluminium-extrusion operations with ETEM's experience in architectural systems and building applications. It also represented a move toward a larger integrated position in international aluminium markets. Following the merger, ETEM remains identified with architectural and industrial aluminium-system expertise within the broader group. Public sources provide limited detail about the post-merger legal status of the ETEM name, management team, financial performance, or brand architecture. Accordingly, the documented history is strongest on the company's Greek origins, its contribution to curtain-wall construction, its Magoula production base, its regional commercial activity, and its integration with Cosmos Aluminium in 2023.

• Architectural aluminium systemsBuilding systems

  ETEM develops integrated aluminium systems for architectural construction. Such systems use engineered extruded profiles and associated components to form coordinated building elements rather than isolated raw-material parts. They support applications across building envelopes and are part of ETEM's historic specialization in architectural aluminium design and production.

• Curtain-wall systemsFaçade systems

  Curtain-wall solutions are a significant part of ETEM's architectural heritage. The company was associated with the first curtain wall used on a Greek high-rise, the Athens Tower, in the 1970s. Its curtain-wall activity reflects the use of extruded aluminium profiles to create lightweight, non-load-bearing external façades for commercial and high-rise buildings.

• Industrial aluminium profilesIndustrial extrusion

  ETEM produces extruded aluminium profiles for industrial applications. These profiles are manufactured to specified cross-sections and can serve as components in equipment, structures, assemblies, and other industrial products. The available reference material confirms the industrial focus but does not identify individual profile families, end-use sectors, or technical specifications.

• Aluminium profiles for windows and doorsFenestration systems

  Aluminium profiles for windows and doors form part of the architectural-system field associated with ETEM. They provide the extruded structural and framing elements used in fenestration assemblies. Specific product-series names, performance ratings, and launch dates are not identified in the available reference material.
