The technology of lightweight thin-walled steel structures (LSTS) provides an opportunity to significantly reduce construction costs through the use of lightweight and durable metal profiles. First of all, it speeds up the installation process, as the structures are easy to assemble, which reduces labor costs and rental of construction machinery. In addition, the LSTS is characterized by high energy efficiency and minimal transportation costs, as lightweight materials reduce logistical costs. Finally, the minimum amount of waste during production and construction using LSTS helps to reduce the total cost of materials.
