JÄKL the brand, which has been used for more than a century in Karvina and is undoubtedly one of the iconic brands in the Czech industry. ArcelorMittal Tubular Products Karviná has long been successfully developing the production and sale of steel sections with a heavy emphasis on the precision and quality of each product. Just for the record, more than 306 thousand tonnes of these sections have been manufactured here over the past five years. If we could place them on the equator, they would circle the earth more than 2.5 times! Their length would reach even 105 thousand kilometres.
The revival comes with a new logo and slogan "KARVINA ORIGINAL," emphasizing the values and place of origin of JÄKL products. The launch of the new concept in Karvina today also reveals the brand's key values: TRADITION-PRECISION-QUALITY.
