Teräsrakentamisen

Teräsrakentaminen refers to the construction or fabrication of structures using steel as the primary material. Steel, an alloy of iron and carbon, is chosen for its high tensile strength, durability, and versatility. This makes it suitable for a wide range of applications, from residential buildings and commercial high-rises to bridges, industrial facilities, and large-span structures like stadiums and aircraft hangars.

The process of teräsrakentaminen typically involves several stages. First, structural engineers design the building or component, calculating the loads and stresses to determine the appropriate steel members and connections. Then, steel components are fabricated in workshops. This involves cutting, shaping, welding, and drilling steel beams, columns, and plates according to the design specifications. Prefabrication is a key advantage, allowing for precise manufacturing off-site, which can speed up on-site construction and improve quality control.

On-site, the fabricated steel elements are transported and assembled. This usually involves lifting the heavy steel sections into place and connecting them, often using high-strength bolts or welding. Safety is paramount during this phase due to the nature of the work and the weight of the materials involved. Teräsrakentaminen offers several advantages, including its rapid construction time, the ability to create large open spaces without intermediate supports, and its resistance to fire and earthquakes when properly designed and protected. Steel is also a recyclable material, contributing to sustainable construction practices.
