Lättbalks

Lättbalks is a type of building component used in Swedish construction, primarily as a floor joist or ceiling beam. The name itself is a portmanteau of the Swedish words "lätt" meaning light and "balk" meaning beam. This suggests its core characteristic is its relatively low weight compared to traditional timber or concrete beams.

These beams are typically manufactured from lightweight materials such as steel or engineered wood products like glulam (glued laminated timber) or LVL (laminated veneer lumber). The specific material composition and design of a lättbalk can vary depending on the intended load-bearing capacity and application. They are often designed for ease of handling and installation on construction sites, contributing to faster building times.

Lättbalks are commonly found in residential and commercial buildings, providing structural support for floors and ceilings. Their lightweight nature can also lead to reduced transportation costs and less strain on foundations. While the term is specific to Swedish construction practices, similar lightweight beam systems are employed globally under different names, reflecting a broader trend towards efficient and lighter structural elements in modern building.
