Teräskatto

Teräskatto is a Finnish term referring to a metal roof, most commonly made of steel. These roofing systems have gained significant popularity in Finland and other Nordic countries due to their durability, longevity, and resistance to harsh weather conditions. Steel roofs are known for their ability to withstand heavy snow loads, strong winds, and significant temperature fluctuations, which are common in these regions.

The material used for teräskatto is typically galvanized steel, often coated with various protective layers such as polyester, polyurethane, or acrylic. These coatings provide additional resistance to corrosion and UV radiation, further extending the lifespan of the roof. Teräskatto is available in a wide range of profiles, including standing seam, corrugated, and tile-like panels, allowing for diverse aesthetic choices that can complement various architectural styles.

One of the primary advantages of teräskatto is its low maintenance requirement. Once installed, it generally needs very little upkeep, making it a cost-effective option over its lifespan. It is also a lightweight material compared to many other roofing options, which can reduce structural loads on a building. Furthermore, steel is a recyclable material, contributing to the sustainability of teräskatto as an environmentally conscious choice. The installation process is often faster than traditional roofing methods, which can also lead to reduced labor costs. The longevity of a teräskatto can often exceed 50 years with proper installation and minimal maintenance.
