    In a world where dependency on technology grows each passing day, renewable energy and accordingly the electrical energy became an inevitable aspect of social life. Electrical energy consumption is one of the most important indicators of economic and social development.

    Especially in our developing country, we face urbanization and industrialization, which emerged as a result of fast population growth, through the increased demand of electrical energy. Therefore, the increase of life standard in Turkey causes the growth of electrical energy demand. We aim to continue our improvement of our place by reaching the growth rate we had planned without making any concessions from quality standard principles in energy sector, which has increasingly growing importance.

    In GGN Engineering, being the new investment towards this direction, we fabricate,

    in our 6000 m² factory established on an open area of 19.000 m²:

    • Geothermal power plants

  • Quality

    Quality Assurance System (QA) and Quality Control System (QC)

    " Quality is a respect shown towards the customer "

     As GGN Engineering, we meet the customer need and expectation at a maximum level. For the purpose of realizing the aimed quality of our company, we continue our customer-based production through Quality Assurance System (QA) and Quality Control System (QC), which we can define as the combination of planned and systematic activities. For this purpose, we have our production certified with ASME S, U Stamp and PP certificates.

    Besides within the framework of continuous quality understanding, our company has ISO 9001, EN ISO 3834-2, EN ISO 1090-2 EXC-2, ISO 14001 and ISO 45001 certificates.

    As GGN Engineering, we have contracted with TUV Austria which is being the notified body and third party inspection company as our quality control unit as being second party for our full time productions.

    Our Quality Control System improves the product quality, and with our Quality Control System it finds the mistakes on the products that are produced through focusing on the result, and thus we enable the continuation of the quality in fabricating the most quality products we can.

    Through our continous Quality Assurance System (QA) the prevention of further mistakes are tried to be achieved by merely focusing on the procedure; and through Quality Control System (QC) we try to produce the most quality products by finding mistakes in the product claimed to have been completed. 

    The role of quality control is to reveal the mistakes within the product after the product is produced and before it is released into the market. Thus, the product quality is protected.

    Quality Assurance (QA), creates a good quality management system, and the evaluation of this system is conducted by inspecting the suitability of the operational system to this quality system by reviewing the quality management system itself. Quality Control (QC) on the other hand is applied by finding the resources of the quality problems and eliminating them by using tools and equipment in order to guarantee that the needs of the customers are always met.

    By November 2016, GGN Engineering has started the preparations for the approval of Nuclear NPT and NR stamps.

  • Steel Fabrication

    The steel usage increased as a result of the industrial development in the 19th and 20th century. Thanks to its wide area of usage, possibility to shape (such as pipe, profile, round iron, flat steel) and technical specifications, steel became the most important construction material of the 21st century. In addition to all of these, steel is the most commonly recycled material in the world. This creates resource and energy conservation.
