Stainless Steel Fire Door Hinges
DIROCK stainless steel fire door hinges are engineered to maintain the integrity of fire door assemblies under extreme thermal and mechanical stress. In a fire event, hinge failure can render an entire doorset non-compliant; our hardware is built to prevent this by combining certified fire resistance with precision mechanical performance.
Our stainless steel fire door hinges use a two-ball bearing design to ensure consistent, low-friction operation across 200,000 cycles while preventing door sagging—an essential requirement for high-traffic commercial and public applications. Manufactured from Grade 304 stainless steel with Grade 316 available for corrosive environments, and offered in a range of architectural finishes, such as brushed stainless steel (SSS), matte black (MB) and polished brass (PB), they adapt to varied project specifications without compromising safety or durability.
Designed to integrate with standard European fire door preparations and compatible hardware systems, DIROCK CE hinges provide architects, contractors, and distributors with a dependable foundation for compliant, long-lasting installations.
