  • About Us

  • GKFORGE Company commenced its operations in 1983 as ZAKŁAD KUŹNICZY Karol Grelowski [Karol Grelowski FORGING PLANT]Since its establishment, the Company has been involved in the production of die forgings and open die forgings. Constantly implementing the development plan and expanding our production base, we work on the implementation of new technologies that guarantee high quality products. GK FORGE Grelowski company has over 30 years of experience in the production of forgings for the automotive, construction and gas industries as well as for the mechanical and agricultural sectors.

    As a universal forge, we have a modern machine park comprising lines of presses with a pressing force ranging from 100 to 1600 tons and induction heating forging machines (1 to 3 inches). Thanks to these machines we can produce forgings weighing from 0.05 to 7 kg using steel of various grades such as e.g. carbon, alloy, stainless and acid-resistant steel as well as brass. Our entire production line is located in one plant, which allows us to shorten the production process to the minimum, and at the same time we can obtain repeatability and high quality products, while maintaining the workpiece prices at an attractive level. Our company can boast of short delivery times. We are able to start production within 3-4 weeks after the order placement date, and thanks to our extensive experience and modern equipment we can meet our customer requirements quickly.
