Certified by the Instytut Techniki Budowlanej (ITB) according to the PN: EN 1303:2015-07 standard, it is assigned class 6.0, ensuring high durability, security, and corrosion resistance. End-users and facility managers value its use in environments where frequent operation and compliance with recognized quality standards are critical.
