Light Steel Construction System is a kind of construction in which the structural components are manufactured from galvanized steel with cold forming process. Having been manufactured under control in factories using state-of-the-art machinery, the structural components are mounted after being transported under protection, to the construction site. Thus, the man-made errors in Light Steel Construction System are minimized. Also, as the manufacturing in construction site is minimized, the damages and faults resulting from this manufacturing are eliminated to a great extent. Even if we only count those qualities, the Light Steel Construction System has superiority over conventional reinforced concrete buildings
Buildings constructed with Light Steel Construction System are lighter than the other buildings with the same size, thus the load imposed on the structure during earthquake is mitigated and this greatly increases the earthquake resistance. The load bearing capacity/weight ratios in Light Steel Construction System is quite high. Furthermore, due to their more efficient plastic strain behaviors compared to the reinforced concrete constructions, light steel constructions do not have sudden structural collapses in case of an earthquake and this ensures the building to remain safe.

The construction stages of steel constructions are also similar to the construction of conventional reinforced concrete buildings. Building is designed; its architectural and static projects are prepared. Then, the manufacturing of steel construction starts. Manufacturing is done in the factory without any flaws. Parts of the construction such as floor, wall, roof etc. are produced in required thicknesses from galvanized steel profiles. Considering the distance of application site and transportation conditions, the steel profiles produced, either profiled or paneled, are sent to the construction site without any loss. The steel profiles, having arrived to the construction site, are mounted by experienced installation teams according to architectural project. Only special screws are used in the installation; no welding is performed. After its installation is completed, the carcass is filled with insulation materials (glass wool, rock wool etc.). The walls are covered with materials like OSB (Oriented Strand Board).
When its construction speed and potential creditability are considered, Light Steel Construction System is extremely advantageous in terms of costs. The leading element increasing the costs in a construction project is the time. Reinforced concrete constructions are completed in a longer period. As light steel buildings can be completed in relatively shorter periods and the flaws related to the workmanship are minimized, it ensures benefits as for cost and time.
It is possible to produce every kind of design with Light Steel Construction System. Whether modern or conventional, all housings can be built elegantly with this system. Regional characteristics and preferences can easily be reflected in such constructions. Residences can be designed as independent houses, twin houses, or row houses. Light Steel Construction System can easily be applied to the non-housing constructions. Schools, hospitals, dormitories, kindergartens, bazaars, marketplaces and alike are social buildings open to public projects that have been frequently completed by Akşan Construction recently. As the safety of life is under focus in Light Steel Construction System, the typical story height in such buildings is 3.00 m. However, it is possible to elevate it with conventional reinforced heavy steel components. Apart from being earthquake resistant, the three-storey housings built with Light Steel Construction System are also important because they meet the expectations of our people. With its fast and economic building technology, Akşan Construction provides the people of our country with beautiful and chic gardened villas. Achieving this by means of cooperatives and the concept projects it developed, Akşan Construction turns the dreams of people about having an earthquake-resistant house with red louvers in a garden into reality.
The construction speed of a building varies according to its size, shape, whether it has a basement floor or not, location, and the climate and topography of the construction area. These parameters are undoubtedly applicable to the low-rise reinforced concrete buildings too. However, compared to reinforced concrete system, it is a fact that the Light Steel Construction System is faster and environment friendly as it is sound and environmental pollution-free, because the steel construction system comes perfectly from factory.
