Technology advantagesModern construction requires the introduction of sophisticated methods, materials and technologies. That is why light steel thin-walled structures have become widespread in construction of low-rise buildings. Advantages of LGSF technologyLight weight of structures The building frame is assembled from C- and U-shaped steel profiles. The metal strip with a thickness of not more than 3 mm is used for production. These features contribute to an insignificant weight of the structure. Thickness of the roll-formed profile wall with layers of sheathing, vapor barrier, internal and external heat insulation, and exterior facing is about 150 mm. The average weight of a square meter of the finished wall does not exceed 200 kg. For comparison, the weight of a square meter of brickwork is up to 1,000 kg. Thanks to a light weight of the structure, it is possible to use any type of foundation. LGSF technology is applied for constructing additions or reconstructing old buildings. Types of foundation Thanks to an insignificant weight of the structure, the following types of foundation can be used:
Simplicity of construction The technological process of LGSF frame construction is prepared at the production site and is accompanied by detailed documentation. A crew of three or four people will implement a turnkey project at the construction site within two weeks. In addition, there is no need to use sophisticated lifting equipment due to a small weight of structures. Accuracy of structures The thermal profile production process is fully automated. Computer programs make it possible to manufacture frame parts with high accuracy (up to 0.5 mm). This significantly reduces labor costs and increases the speed of erection. Rapidly-erected buildings Light weight of structures, computer accuracy of each element, full compliance with project and assembly documents, as well as appropriate marking of each part and unit have brought LGSF technology to the category of rapid construction. Buildings are assembled by means of self-tapping screws and an electric screwdriver. Construction in all weather and seasons We use the so-called dry method of construction suggesting that the whole process of building construction is reduced to frame assembly, sheathing, and facing and is carried out only with the help of fasteners. Long useful life The steel profile with a protective galvanized layer has a guaranteed service life of more than fifty years. Its properties are not affected by humidity or temperature differences (material is capable of withstanding temperatures ranging from -60 to +100 degrees). Light steel thin-walled structures are not susceptible to microorganisms and fungi. Therefore, LGSF buildings are also distinguished by high strength and long useful life. Convenience and comfort Frame construction technology guarantees absence of shrinkage joints and cracks. Thermal profiles used inside the buildings create comfortable living conditions (humidity, temperature). Multi-layer panels ensure heat, noise, vibration and moisture insulation as required. Environmental friendliness Materials used for frame construction comply with GOST:
The construction process is also clean. There is no technological waste or debris left at the site. Cost effectiveness The construction cost can be reduced throughout the whole process starting with the foundation laying stage (possibility of construction on a shallow foundation). Material delivery, unloading and lifting costs are considerably decreased, with labor costs being minimized. Operation costs are also characterized by high effectiveness. LGSF resistance to atmospheric and biological influences makes it possible to minimize maintenance costs as well. Safety LGSF technology is associated with the use of flash-resistant and non-combustible materials. Fire safety became a key point for application of this technology in construction of social buildings, as well as administrative and commercial buildings. Thanks to elasticity of the steel frame reinforced by additional ties, the building is capable of withstanding earthquakes with a magnitude of up to 9 points on the Richter scale. Architectural capabilities LGSF technology has become a real breakthrough in cost-effective construction of low-rise buildings. It can be used in typical or individual construction of residential and public buildings. The technology plays a very important role in reconstruction of old houses. It is widely used with the aim of strengthening load-bearing structures and internal partitions, intermediate floors, performing roof repairs, and constructing attic rooms. It is possible to create large (up to 12 m) spans without installation of additional supports. |
