Camax Hardware is proud to announce that our concealed door hinges have achieved UL10C 3-hour fire-rating certification. This milestone reflects our commitment to engineering door hardware that not only enhances architectural design but also guarantees safety in emergencies.
Why Fire-Rated Hardware Matters?
Today's architectural landscape demands both visual sophistication and safety compliance. Modern buildings—from luxury hotels and corporate offices to hospitals and educational facilities—require hardware solutions that maintain clean, minimalist aesthetics while meeting stringent fire safety regulations. The challenge lies in achieving seamless design integration without compromising life safety requirements during emergency situations.
In this article, we will explore what concealed fire door hinges are, why UL certification matters, and how Camax’s fire-rated invisible hinges bring both safety and elegance to modern buildings.

What Are Concealed Door Hinges?
A concealed hinge represents sophisticated engineering that operates completely flush within the door and frame assembly. Unlike traditional butt hinges, concealed fire door hinges utilize multi-link connection systems that remain entirely hidden when the door is closed, creating an uninterrupted, premium aesthetic.
When engineered for fire-rated doors, these hinges must meet strict requirements for strength, material durability, and thermal resistance. Camax Hardware produces fire-rated commercial door hinges for metal doors and fire-rated concealed hinges for wooden fire doors, ensuring compliance across various building applications. The construction typically involves high-grade steel or stainless steel materials, engineered to maintain structural integrity throughout extended fire exposure periods. This ensures the door assembly remains properly positioned, self-closing, and securely latched during emergency conditions.
1. Key Advantages of Fire-Rated Concealed Hinges
Modern design: Completely hidden hardware creates seamless door surfaces ideal for high-end commercial and luxury residential projects.
Tamper resistance: Inaccessible components eliminate traditional vulnerabilities associated with exposed hinge pins.
Smooth operation: Precision engineering ensures effortless door movement even with heavy fire-rated assemblies.
Versatile Applications: Suitable for both interior and exterior fire door installations.
Tips: What Are the Critical Differences Between Fire-Rated Concealed Hinges and Standard Concealed Hinges?
Standard fire-rated hinges provide safety but lack the aesthetic and security advantages of concealed designs. Fire-rated invisible hinges deliver both – functionality plus elegance, making them a preferred choice for architects and contractors who want design without compromise. The fire rating encompasses not only the hinge mechanism itself but also the installation methodology and supporting protection systems required to maintain door assembly integrity under extreme thermal conditions.
What Is Fire-Rated Certification?
The UL10C 3-hour fire rating represents one of the most stringent certification standards in the building hardware industry. This designation confirms that door assemblies equipped with Camax concealed door hinges can withstand continuous fire exposure for up to three hours while maintaining their protective barrier function.
So, why and when use fire-rated concealed hinges?
Fire-rated door hinges become mandatory in numerous building applications, including stairwell access doors, corridor separations, mechanical room entrances, and exit pathway components. Building codes typically require these specialized hinges in occupancies such as healthcare facilities, educational institutions, hospitality venues, and high-rise residential buildings.
Architects, contractors, and building owners consistently seek UL certification because it provides universal recognition, ensures regulatory compliance, and offers legal protection. The UL mark represents third-party verification that products meet rigorous safety standards, providing confidence for all project stakeholders.
