LSF (Light Steel Frame) construction is a method of building homes. This material, also known as light steel structure, uses coated galvanized steel sheets as the main construction element, replacing concrete and iron. It is an innovative, resistant, light and low thickness model. The fact that it does not use mortar means that the construction weighs less. At the same time, it enhances a wide variety of finishes, which allows for enormous architectural versatility.
The LSF construction is made up of high quality elements providing comfort, durability and safety.
Currently we can see LSF construction in commercial works, schools, hospitals, buildings, warehouses, restaurants, hotels, penthouses and homes.
“Light steel as the main material of a building provides comfort, safety, resistance, versatility, durability and sustainability!”
Process of LSF Construction:
• Foundation;
• Structure;
• Roofing;
• Insulation;
• External and internal coating;
• Electrical, water and hydraulic installations;
• Windows and doors framing;
• Carpentry and interior finishings.
Construction of Homes in LSF is Increasingly Used in Portugal
Its high resistance and reduced thickness make it possible to develop various housing structures more quickly and at lower costs.
Ensure comfort and safety with thermal and acoustic insulation and resistance (seismic and fire). This system allows rehabilitation, renovations, expansions or constructions from scratch with modern lines and superior quality materials without harming the environment.
LSF is used in the Ground-up Construction of Private Homes Up to 2 Levels
This new technique offers numerous advantages in homes. Other than that it is a very suitable method for remodeling and renovations of historic buildings, for example as due to the lightness of its components, they are not very aggressive for this type of structure.
You can find LSF in various works and also as an additional component whenever it is necessary to alleviate or mitigate the total load of the structure in question.
“LSF is construction system using a lightweight, thin structure, with significant advantages over the traditional method!”
Advantages of LSF Construction:
• Safety: Solid and robust material;
• Seismic Resistance: Steel absorbs energy and twists without breaking;
• Fire Resistance: Non-combustible material on walls and ceilings;
• Acoustic and Thermal Insulation: Light steel insulation on the outside and mineral wool and plasterboard on the inside, which contributes positively to energy savings;
• Speed in Construction: The steel structure, as it is lighter than the traditional one, allows for easier handling. Additionally, steel does not require waiting time for concrete to cure;
• Durability: Requires little maintenance, resists fungi and mold, does not rot or crack;
• Versatility: Greater architectural freedom compared to other construction methods;
• Economy: Lower expenses with labor and transport of materials due to its characteristics;
• Sustainability: Use of recyclable materials. Manufacturing and assembly with lower CO2 emissions and reduced water use;
• Excellent for Rehabilitation: Less aggressive materials and less production of rubble and waste.
Key Benefits of LSF Construction:
• Material with the best cost/benefit ratio;
• Better resistance/consistency/weight ratio;
• Price stability;
• Shorter and less unpredictable construction period;
• Production in accordance with internationally established standards;
• Greater environmental responsibility (sustainable materials, 100% recyclable and less waste in construction);
• Absence of chemicals;
• Less maintenance required and greater longevity.
Limitations of LSF Construction:
• It is not recommended for the construction of very tall buildings;
• More than two floors can compromise the stability of the structure;
• It is convenient to evaluate the distribution of forces in the building structure, to ensure perfect resistance;
• Need to use more efficient frames and glass.
Main Materials Used in LSF Construction:
• Galvanized steel profiles;
• OSB boards (composed of wooden sheets for covering and reinforcing);
• Mechanical fixing materials (unlike conventional construction where elements are fixed together using mortar);
• Plasterboard;
• Stucco plastering (systems applied to the exterior to protect the building).
Conclusion:
LSF construction ensures resistance, safety, high performance, efficiency, durability, comfort in an innovative, economical and sustainable construction.
The cold-formed lightweight steel structural system complies with all global certification standards (CE, EURO-CODE, ASTM, ABNT) and allows the construction of residential or business spaces as well as remodeling and rehabilitation.
