Lättbalk

Lättbalk is a term of Swedish origin that translates to "light beam" or "light joist." It refers to a type of structural component used in construction, particularly in Sweden and other Nordic countries. These beams are designed to be lighter in weight compared to traditional solid timber or concrete beams, while still providing adequate load-bearing capacity for their intended applications.

The primary purpose of a lättbalk is to reduce the overall weight of a building's structure. This can lead to several advantages, including easier handling and installation on site, reduced foundation requirements, and potentially lower transportation costs. They are often manufactured from engineered wood products, such as laminated veneer lumber (LVL) or glulam, or sometimes from lightweight steel profiles. The specific material and design of a lättbalk will depend on the load it needs to support and the span it covers.

Lättbalks are commonly used in floor and roof construction. They can be found in residential buildings, commercial structures, and industrial facilities. Their design often involves a specific profile, such as an I-beam or a box beam, which optimizes material usage for strength and lightness. The precise engineering of these components ensures they meet relevant building codes and safety standards. While the term is Swedish, similar lightweight structural elements are employed globally under different names, all aimed at achieving structural efficiency through reduced weight.
