Frequently Asked Questions

What is the advantage of a continuous geared hinge?
Unlike traditional butt hinges, continuous geared hinges distribute the door's weight along the entire frame. This prevents door sagging and significantly reduces stress on the hardware, extending the lifespan of both the door and the frame.
Are these hinges suitable for fire-rated doors?
Yes, our hinges are fire-rated for up to 3 hours on metal doors and 90 minutes on wood composite doors when used with the appropriate studs.
What materials and finishes are available?
The hinges are made from high-quality aluminum alloy. Standard finishes include anodized silver and black, but customized colors are available upon request to match your building's design.
Do geared hinges help with safety?
Yes. Because there is no gap between the door and the frame along the hinge side, it prevents fingers from being pinched, making it a safer option for schools, hospitals, and public buildings.
Can I request a custom length?
Absolutely. While our standard lengths are 83'', 95'', and 119'', we can provide customized lengths to fit your specific door height requirements.
What is the weight capacity for these hinges?
Our heavy-duty continuous geared hinges can support doors weighing over 75kg, ensuring smooth operation even for high-use, heavy-traffic entrances.
