Frequently asked questions

A building whose load-bearing system — columns, beams, trusses and connections — is made of structural steel sections. Members are cut, drilled and welded in the workshop, then assembled on site with bolted or welded connections. Floors, facade and roof sit on this frame.

Steel stands out when site time must be short, when wide spans are needed (warehouses, factories, halls), when weak ground calls for a lighter structure, and when future dismantling or extension is expected. It is not the right choice for every project; the decision weighs ground data, architecture, intended use and budget together.

Steel is a ductile material: it dissipates energy by deforming before it fails. Because the building is lighter, the seismic load acting on it is lower too. This behaviour does not come by itself — the structure must be designed to the Turkish Building Earthquake Code (TBDY 2018) and the Turkish steel design regulation, connections must be detailed correctly, and fabrication and erection must be inspected.

Steel does not burn, but it loses strength at high temperature. Load-bearing members are therefore protected for the period required by the building's occupancy class, using intumescent paint, gypsum or cement-based boards, or sprayed coatings. The required fire-resistance period is set by the Turkish Regulation on Fire Protection of Buildings.

Unprotected steel rusts when exposed to moisture. Protection is chosen for the environment the structure will stand in: surface preparation (blasting), a primer and top-coat paint system, hot-dip galvanising, or both combined. A dry indoor space does not need the same protection as a coastal or chemical environment.

First we collect your requirements and site information, with a site visit if needed. A preliminary design and quotation follow. After agreement, the structural design and shop drawings are prepared and the necessary approvals obtained. Members are fabricated in the workshop, surface protection is applied, and they are shipped to site and erected. Concrete works such as foundations can run in parallel with workshop fabrication.

The location of the building, its intended use, approximate dimensions (width, length, height), an architectural design or sketch if available, a ground investigation report, special needs such as cranes or mezzanines, and your target schedule. You can fill in the quote form even if some of this is not ready yet; we will clarify the rest together.

No. The configurator builds a typical structural system from the dimensions you enter and calculates approximate member lengths and areas. It is a preliminary estimate and does not replace structural design or a formal quotation. The final take-off and price are set in a written quotation after a site survey and engineering design.

Yes. On plots where a risky-building decision has been issued under Law No. 6306, the new building can have a steel load-bearing system. The permit process is the same as for other buildings; the structural design is prepared by a licensed civil engineer and approved by the relevant authority. On narrow plots and streets, dry assembly helps shorten site time and reduce the impact on neighbours.

The answer is specific to the building. The existing structural system is examined first and a performance analysis is carried out. If suitable, methods such as steel bracing, steel jacketing, additional frames or floor strengthening can be used. For some buildings rebuilding is the better option; the decision rests on the engineering report.

Yes. Steel-framed buildings also fall under Zoning Law No. 3194: a building permit, approved designs and building inspection are required. Exceptions for temporary or small structures vary by municipality; check with the authority before you start.
