Our staff, which specializes in metal processing and assembly, has become a preferred company for many years by the leading Transformer manufacturers in the market.

First periods…

In the process of growth, we replace the low-tech construction products that we have already manufactured; In recent years, we have received transformer and boiler accessories which undergo very precise manufacturing procedures and which constitute a significant complementary production stage of the Transformer industry, subject to the latest technology testing and calibration controls.

Long-term success…

With the energy sector that we have met the demands of metal construction for many years, with the confidence of being able to speak the same language; In the production of metal components we produce in the quality and specifications required in the sector, starting from the pre-operations of the raw metals, we can serve with capacities above the average of our sector in separate production lines for machining, assembly welding, sandblasting, painting, dismantling and reassembly stages.

We grew up…

As DETSA family; We have been evaluating the synergy obtained by combining our warm and intimate relationships with our partners, executives, employees and customers with a professional perspective, DETSA Transformer, which has all the ISO Quality Certificates that have more than 100 employees and 6,000 m² closed area..

Our Works


Heavy Steel Constructions

With our flexible manufacturing processes, we have been successfully implementing project-based special manufacturing orders for all sectors, primarily the energy sector, for many years. Thanks to our production area and machine park capacity we proudly offer to our customers, we are able to manufacture heavy metal in special sizes in our own world.

Metal Processing

By mobilizing the technological possibilities that we have achieved through the harmonious work of our Project Management, Manufacturing, AR-GE and quality units, we have meticulously processed a variety of steel materials in our machine park, which consists of highly sensitive and automated systems.

Exclusive Welded Constructions

Mortar between the bricks of the buildings and the basic elements holding the nails together in the wooden structures is the most important factor which ensures that the weld metal structure stays together in the metals. We, as Detsa, show all the necessary dedication to our welding technology and workmanship in our production processes.


Steel Sandingblasting

The sandblasting process for preparing the metal surfaces before dyeing is carried out in our high-capacity special sanding chambers. Small, medium, large, complex geometric structures and sensitive parts can be sandblasted into our bodies.

Steel Painting

All kinds of metal surface primer and topcoat applications are made by our experienced employees in our factory. Appropriate painting procedures are applied according to the ground and the paint thickness is subject to continuous quality control processes at micron level.

R & D

Our company has made very serious contributions to manufacturing processes in fields such as welding, precise lathe, CNC programming, laser cutting with support of AR-GE unit, MARKA, TÜBİTAK and KOSGEB collaborations and expert engineer staff.
