In addition to villa type single or two-story buildings, we also build four or five-story mass housing estates. Professional precautions against fire and earthquake have been taken in our buildings. In addition, since steel construction conducts heat well, very detailed heat insulation details are applied. These details are successful solutions that have been accepted and implemented as a result of our joint work with project groups that we can call the doyen of steel in the world. Galvanized sheet metal profiles are used in the buildings we construct with light steel construction systems. When required by the static calculation, the carcass is also formed from heavier profiles. We work according to the key delivery method in projects. However, in many projects, we work only on the steel construction or fine structure parts of the work.
