KONČAR – Metal Structures

Precision shaped by experience. Modern welded components for energy, mobility and industry.

KONČAR – Metal Structures

Experts for large-scale solutions - from the first spark to the finished product

We harness our machinery and expertise to manufacture large-scale, customer-specific welded components. Such impressive solutions pose a challenge even for the largest companies in the industry, but we excel at advanced projects where we can best showcase our capabilities.

Our core products are transformer tanks, and we also deliver generator components, rail vehicle  components and isolated phase busbars. Our dominant technology is welding and metalwork, and our manufacturing capacity is defined by cranes with a lifting capacity of up to 2x63 tons and a maximum lifting height of 11 meters.

Transformer tanks

Transformer tanks

We manufacture customer-specific transformer tanks for large (LPT) and medium (MPT) power transformers. In addition to structural steel, we also use non-corrosive stainless steels, such as aluminium and copper. 

Our impressive solutions are completely customer-specific, to best meet all of their needs and requirements. We participate in all stages of the project, from design to commissioning.

Components for generators and motors

Components for generators and motors

Experience didn't come quickly or easily. We are at the forefront of our industry, manufacturing advanced, dynamically loaded and machined components for HPPs and wind farms, as well as HV electric motors. 

We also manufacture welded structures for nuclear power plants that meet rigorous quality requirements.

Isolated phase busbars

Isolated phase busbars

Our isolated phase busbars are customer-specific products. Design, development and manufacturing of these precision solutions also involves prefabrication of load-bearing structures.All components are assembled on-site, and we support our customers throughout the entire process, up to the commissioning.

Heating, impulse voltage, and short-circuit current tests are conducted for each distinct busbar type.

Rail vehicle components

Rail vehicle components

In 2009, we obtained the highest industry certification HRN DIN EN 15085-2 Level CL1 under the supervision of SLV and Deutsche Bahn. We then branched into the development and manufacturing of the most complex steel structures and components for rail vehicles.

We utilize state-of-the-art robotic welding technologies, large-scale machining, anti-corrosion protection, and various non-destructive testing methods, and consistently monitor these advanced procedures.
