rautarungosta

Rautarunko refers to a type of construction where the primary structural elements are made of iron or steel. This method of building has been widely used for industrial structures, bridges, and large public buildings. The use of metal frameworks allowed for taller and more expansive structures than were previously possible with traditional materials like stone or wood.

Early examples of rautarunko construction can be found in the 19th century with the rise of industrialization. The development of techniques for mass-producing iron and later steel made these materials more accessible and affordable for construction. This led to iconic structures such as the Eiffel Tower and many railway stations and warehouses across Europe and North America.

The advantages of rautarunko include its high tensile strength and durability, allowing for lighter and more slender structural components. It also offers greater resistance to fire and pests compared to timber. However, iron and steel are susceptible to rust, requiring protective coatings and ongoing maintenance. Modern construction often utilizes steel framing, which is a refined version of early rautarunko principles, incorporating advanced alloys and fabrication techniques for enhanced performance and safety. The term itself is Finnish, translating directly to "iron frame."
