(Polidomes International ) manufactured structures to have the CE mark as proof of compliance with the Construction Products Directive (CPD), as a result of which we are able to introduce our building structure elements to the European Union markets.
A prerequisite for conducting conformity assessment is the organization and possession of a described, implemented and certified Factory Production Control (FPC) system by Polidomes International.


PN-EN ISO 3834-2 certification assures 2KB Karolina Bertman & Krzysztof Bućko s.c. (‘Polidomes International’ ) meets all quality requirements for welding metallic materials. It concerns the quality of services of welding plants, as well as establishes quality standards for welded products that must be met in order for the products to be admitted to the market.
