Light Gauge Steel Framing (LGSF) System is a structural system made of Cold Formed Steel (CFS) Profile Frames. The structural behavior of this new construction system is derived from the traditional wooden frame systems. The new material that has been used in LGSF system which is the profile cold-rolled from sheet steel is an industrial material that needs the control of computer systems for accuracy. The structural system has been examined for more than 40 years in the construction practice. It is an alternative building material for the world and for Turkey in the last years, specifically for 1-2 storey single family houses.This study aims to make analysis of Light Gauge Steel Framing system which is a developing construction system, to define efficient uses of the system at the moment and to propose new ones for the future. To obtain different conceptions and theories on the system has been the main goal of the evaluation part. To fulfill this goal; first, the different examples around the world have been examined in different aspects in detail to make a comparative evaluation, then, new opportunities in the usage area of LGSF system have been suggested. A Temporary Post-Disaster Housing Unit. has been studied as a case study.The case study is the heart of this study whereas the LGSF system has been examined by its lightweight, accurate, easy & fast montage, storable behavior characteristics as well as the structural properties. .Temporary housing. is still a demanded study for Turkey. To design a unit example with the new used LGSF system has been a study that helps both to show the benefits of LGSF in a temporary-housing and the new construction opportunity which fulfills the requirements of a temporary post-disaster housing unit. in Turkey conditions with the Turkish building market materials.While these issues have been worked out, the architectural approach has leaded this study. Design processes of the various examples have been inspected and the new project has been studied in a way to search .how architecture can use this system.
