The construction sector in Portugal and Europe in general is undergoing a significant transformation, driven by the growth of Light Steel Frame (LSF) construction. This technique, known for its efficiency and sustainability, is gaining prominence in both residential and commercial projects. In recent years, the use of LSF has grown in Portugal, with an increase of approximately 25% in the number of projects carried out using this methodology. The main benefits include reduced construction time, less waste of materials and improved energy performance, in line with increasingly stringent environmental and energy efficiency requirements in Europe. Experts point out that the growth of LSF is driven by the growing awareness of sustainability and the search for fast, high-quality housing solutions. In addition, the system’s flexibility and lightweight characteristics allow builders to meet a variety of demands, from single-family homes to large commercial developments. As the construction industry evolves, LSF stands out as a viable and innovative alternative, promising to continue its rise in the Portuguese and European markets. With the demand for efficient housing solutions on the rise, the Light Steel Frame technique is consolidating itself as a fundamental pillar for the future of sustainable construction.
