teräsylinterien
Teräsylinterien, often translated as "steel cylinders" or "iron cylinders," is a term primarily associated with early Finnish industrial history and the production of metal goods. The term refers to the manufactured metal tubes, typically made from iron or steel, that were essential components in various industrial processes and products. Their manufacture and use were a significant marker of Finland's transition towards industrialization during the late 19th and early 20th centuries.
The production of teräsylinterien was often linked to foundries and metalworks, where raw iron ore was smelted
The development of techniques for producing reliable teräsylinterien was crucial for the growth of Finnish industries
