Certificates
For KJG, the most important factor in production and services is quality; this is also demonstrated by the number of STN and ISO certificates relating to the quality and durability of the company’s products.
In addition to the production process, the quality factor is also conditioned by the properties of the input raw materials. For this reason, KJG cooperates primarily with European suppliers with the certified quality management ISO 9001.
