This is a high-performance architectural hinge designed for durability, fire safety, and long-term use. It is certified to EN 1935:2008 Grade 11, meaning it meets a high standard of strength and operational performance for door hardware. The hinge has been fire tested for 30 and 60-minute fire doors (FD30/FD60) when used with an intumescent hinge pad, helping to maintain fire resistance in door assemblies. It is built for heavy-duty use, tested to 200,000 opening and closing cycles, and offers Grade 4 corrosion resistance, making it suitable for environments where reliability and moderate exposure to moisture are important.
