Quality LGSF solutions for sustainable constructions

A steel structure construction is built using galvanized steel profiles that form the load-bearing structure of the building. On the market, this type of construction system is used for houses as well as for halls, offices, commercial spaces, extensions, attic conversions, building floor additions, or modular constructions. The main advantages of steel structure buildings are high execution precision, fast assembly, and lower weight compared to some traditional construction solutions.

Yes, steel frame houses are considered very durable when they are properly designed and executed. Galvanized steel provides high structural strength and performs well in seismic areas, as it can absorb and dissipate the forces generated by seismic movements more efficiently than some more rigid construction systems, which are more prone to cracking. At the same time, the overall durability of a building does not depend only on the material itself, but also on the structural design, the type of foundation, the way the connections are executed, the corrosion protection, and the quality of the construction process.

In general, the cost of a house built on a lightweight steel structure is lower than that of a traditional masonry construction. The final price depends on several factors: the size of the project, the level of insulation, the type of finishes, the envelope solutions, transport, and on-site assembly. One of the important advantages of lightweight steel structures is the efficiency of the construction process. Structural elements are produced with high precision and assembled quickly on site, which significantly reduces the execution time and, implicitly, labor costs. In addition, a steel structure has a lower weight than a traditional brick or concrete construction, which leads to lower foundation costs. Besides the initial construction cost, the long-term operating cost should also be considered. A house built on a lightweight steel structure, executed correctly and equipped with efficient insulation solutions, can achieve high energy performance in line with nZEB standards, contributing to reduced energy consumption and lower maintenance expenses.

One of the advantages often associated with steel structure constructions is the speed of execution. Lightweight steel structures are assembled much faster than many traditional construction solutions, which can significantly reduce the time required to build the structural framework compared to traditional masonry. However, the exact duration depends on several factors, such as the complexity of the project, the preparation of the foundation, the availability of materials, and the way the construction site is organized.

Lightweight steel structures are not used only for houses. This construction solution allows the development of a wide range of projects, such as industrial halls, commercial spaces, offices, extensions, additional floors, attic conversions, modular buildings, carports, or structures for photovoltaic panels. Thanks to their design flexibility and fast assembly, lightweight steel structures are widely used in residential, industrial, and commercial sectors.

Yes, lightweight steel structures perform very well in seismic areas when they are properly designed and executed. Steel has elastic properties that allow it to absorb and dissipate the energy generated by seismic movements more efficiently, while the lower weight of the structure can result in reduced loads compared to heavier construction systems. However, seismic performance always depends on the structural design, the correct sizing of the foundation and connections, as well as the quality of execution.

These are some of the most common questions when it comes to lightweight steel frame houses. In practice, aspects such as thermal bridges, condensation, or corrosion must be considered from the design stage of steel frame houses, but modern insulation and protection technologies can significantly reduce these risks. The use of galvanized steel, together with proper insulation solutions and well-designed construction details, helps protect the structure and maintain its performance over time. Ultimately, the behavior of the building largely depends on how the entire building envelope is designed and executed.

Yes, permanent steel structure constructions require a building permit and the related documentation. Steel halls, being fixed buildings designed for long-term use, fall into this category and require the approvals and permits provided by the applicable legislation. The same applies to other types of steel structure constructions, such as commercial spaces, offices, or extensions, when they are intended as permanent structures.

Yes, lightweight steel structures are frequently used for extensions, additional floors, and attic conversions of existing buildings. The low weight of the system represents a major advantage in such projects, as it limits the additional load on the existing structure and foundation. This type of solution allows faster interventions and easier integration into the existing building. However, before any such work is carried out, a technical assessment of the building and a design adapted to the intervention are required.

You should analyze several essential aspects: experience in similar projects, design and production capabilities, the clarity of the offer, the type of steel and protective treatments used, certifications, the execution timeline, and the existence of a real portfolio of completed works. It is also important that the company properly understands the entire process, from site analysis and selecting the appropriate type of foundation to the technical details that influence the final cost and safety of the construction.
