For fire-rated metal door manufacturers, integrating non-certified hardware is a significant risk that can compromise the entire door assembly's integrity, leading to failed inspections, safety hazards, and potential legal liabilities. D&D Hardware understands this critical requirement, which is why our core concealed hinge products are rigorously tested and certified by independent laboratories to meet the most stringent European standards.

A CE door hinge is a door hinge that has been independently tested and certified to meet the European CE marking requirements under the Construction Products Regulation (CPR). For commercial fire doors, CE certification is not optional — it is a mandatory requirement in the European market and increasingly adopted in international projects that demand verifiable third-party compliance.
