The use of cold-formed steel bearing elements in structures requires consideration of some different rules in addition to the sizing rules of traditional steel structures, as the behavior of all elements under resistance and the physical moments of collapse are quite different from those of the hot rolled heavy steel bearing elements. In addition, the profile shapes of the elements used, the joining tools and their use in the building are different from those of conventional steel structures in many areas. For this reason, current steel structure standards do not include this type of structure.

The Cold-formed industry team has developed special design calculation aspects by conducting research and development studies with valid load standards based on the regulations prepared by many countries, especially in Europe, and develops the results of the studies, international investigations and finite element results. In addition to the conventional design methods of conventional steel in cold-formed industry production processes, the experience gained with R&D and P&D is taken into account.

National and international publications on this subject are always being researched. Cold-formed industry design methods make up-to-date changes by taking the results as reference.

Cold-formed industry is based on the conditions given in TSEN 1991-1-3 for snow loads defined in TS 498 international standards, excluding snow, wind, earthquake, design load values ​​taken during the design phase. Wind loads take the values ​​given in TS EN 1991-1-4. It takes earthquake code conditions for earthquake effects. Load combinations that will create characteristic resistance for strengths are selected and depending on Usability, ensuring that the structure fulfills what is expected under the foreseen conditions of use, ensuring its resistance to environmental effects and not being affected by non-structural elements, ensuring physical conditions, Usability conditions are determined by the change of the resistance principles system and all energy limits such as acceleration. conditions are operated completely independently of other strength conditions.


Delivery deadlines of the projects; It is determined by manufacturing, production, logistics and application times. Structures made with CFIS technology are affected by conventional production at the least level. It is completed much faster than structures formed with traditional construction techniques.


The fact that CFIS productions are lighter than conventional structures acts flexibly against the resistances acting during earthquakes. It is very aesthetic and light compared to the traditional system.

It does not cause collapse in sudden bursts of energy during earthquakes. It provides a superior, healthy building character.

Architectural designs are not limited, many original and specific structures are successfully completed.


CFIS structures are permanent structures that you can use for a lifetime. CFIS minimizes the damage to the ecology of nature in construction sites that offer dry construction technique. It ensures a superior permanent structure by minimizing the construction site processes without depending on the harsh behavior of natural conditions.

CFIS productions are delivered faster than conventional building models. External financing loans are taken like traditional structures

In your current land, it provides the opportunity to have galvanized superior structures by providing optimum opportunities for the structure of your dreams.

It is the process of precise production of projects designed with CAD-CAM software using advanced engineering calculations, using high-strength flat structural steel in the form of a band, in fully advanced CNC controlled and minimum precision machines.

With CFIS technology;

  • Exposure is made with a laser printer on each profile produced.
  • In U, Z, C, CPLUS, SIGMA, SIGMA PLUS sections, the structure is produced according to the design.
  • In accordance with the needs of the project, CNC-controlled forms of installation and assembly spaces are given in varying cross-sections.
  • In structures where C, SIGMA, Z, U profiles will be joined with bolts, dimple application allows preventing screw pots.
  • With CNC technology, the galvanized coating in the end and installation gap areas of the profiles does not deteriorate, and the corrosion resistance continues.
