Why Steel Structure?


Surwey Work

Topographical elevations, axles and floor elevations, which should be on each floor of the building where the production will be made, are sent to the project group. The project group corrects possible errors between the two by overlapping the existing projects with the relay work. Makes the project to be given to production.

3D Project Preparation

The survey work from the cartographer is overlapped on the existing project and corrected if there is any malfunction or error in the system. The 3D model is then finalized. After the 3D model, the anchor system, manufacturing project , material cutting and hole marking sketches are taken, and finally the assembly sheets are taken.

Anchorage System

Production of anchorage elements from the project is made in kits and shipped to the assembly site. In place of burial anchors at the axle and elevation, the anchor is placed in place in the control of the cartographer. It is important to note that the anchorage system is mounted so that it does not move during the concrete stage.


Manufacturing Stage

Material sections and total quantity to be used in incoming order are determined and production materials are provided 
Material certificates of the supplied materials are obtained and shipped to sandblasting.
15-20 micron thick shopprimer is applied to the sandblasted material. Shopprimer prevents the rusting of the sandblasted surface.

Material After Blasting;

• Length cutting
• Marking
• Drilling
• Pre-assembly (manufacturing)
• Welding
• Cleaning
• Paint
• Packing and stock
• It goes through loading and dispatch stages. In the manufacturing stage, one or two samples are taken from the materials and cutting and tensile tests are performed.

After Welding Materials;

• Penetration Test is performed.
• Mechanical Welding Test is performed.
• Welding Films are taken.
• The paint thickness of the painted material is measured and documented by the quality control authority.
All of these tests are prepared and delivered to the customer at the end of work by preparing a quality control file.
Tests can be given in part in every material shipment upon request.
When transporting to the site, attention is paid to the delivery of materials that do not interfere with the axle assembly.


Assembly Stage

• Assembling of ancillary anchors in embedded steel
• After the completion of the relief works of burial anchorages, production will be started by placing anchorage orders.
• The buried anchorage elements will be assembled in the first stage with the topograph. 30mm Graut shall be left under the anchor plates. After the assembly is completed, graut filling will be made.
• In the assembly stage, firstly, assembly is made according to the axle and elevation according to the order specified in the work program.

The Assembly Stage;

• Anchoring system
• Column placement
• Laying of main beams
• Installation of intermediate beams
• Completing the system by tightening the bolts to the desired value
• Touch up paint
• Provisional acceptance

Measures To Be Taken At The Assembly Site;

1- The construction site chief (Civil Eng.), Occupational safety responsible, supervisor, foreman should be present at the assembly site in terms of quality and safe assembly.
2- Before the installation starts, guardrail or strip tape and warning signs should be hung around the installation site.

Additional Info;

• The materials shall be stocked in the stock area at the assembly site, with the cold stamping number on the materials.
• Installation shall be made in the order of columns, beams and floor beams.
• The assembly packing list of each material whose receipt has been cut shall be attached.
• The manufactured ankars will be assembled at the axis and elevation in the field with the topography.

Responsibilities of the Customer during Assembly;

• Storage area
• Crane installation site
• Preparation of the installation site
• Assembly work safety
• Electricity
• Water



As in all projects, Strengthening Projects are meticulously implemented by our expert staff from the project design stage to the project delivery. KONAKSAN is also beside our customers in strengthening projects.

Analysis of the current situation is very important in retrofit projects. After a detailed examination of the current situation by our expert engineers in the field, the project steps become clear. After this stage, the project plan is made and the necessary project steps are taken.

A draft project plan is prepared after the necessary technical examination and technical studies are completed based on the project plan. Afterwards, the project is finalized by sharing with the customer. After the draft project approval, the necessary technical analysis and static project studies are completed.

After the technical design and project work is completed, the necessary manufacturing plans and assembly plans are made and the project delivery is made with 100% customer satisfaction.
