We constantly monitor and improve the quality of our products. We develop our products in our in-house modern specialized research and development department. We use technically advanced equipment and machinery to determine the important parameters of the product. Our products are subject to external certification in the Technický a zkušební ústav stavební Praha, s. p., (Technical and Test Institute for Construction), branch office Pilsen. For the entire period of certificate validity, proper operation of the production control system is periodically supervised as well as compliance with requirements set down on the products. On the basis of the results, we issue certificate of conformity according to the applicable legislation.
To guarantee stability and effectiveness of production process, we have introduced the international standard for quality management system ISO 9001 in 2008. We are re-certified each year.
