Bloxer Ronchi has built fire-rated glazed doors, windows and screens in steel, stainless steel and aluminium at Villafranca Padovana since 1985. Its certification page names the third-party bodies behind that work explicitly — Efectis France, Istituto Giordano and CSI — against UNI 9723, EN 1634-1 and EN 1364-1. In 2025 it obtained certification from Istituto Giordano for pedestrian doorsets on escape routes under System 1 attestation, referencing UNI EN 14351-1. Further published certifications cover smoke tightness to class Sa, VKF approval for the Swiss market and an Intertek mark. The certificate numbers themselves sit inside the technical login area.
