1. Material & Anti-Corrosion Performance

Constructed from heavy-gauge carbon steel, this hinge offers superior strength and rigidity to support heavy doors and panels. The zinc plating provides a reliable barrier against rust and corrosion, making it suitable for use in indoor industrial environments, workshops, and other dry to moderately humid conditions.

2. Integrated Oil Cup for Long-Term Lubrication

The built-in oil cup allows for easy periodic lubrication of the hinge pin. This feature ensures smooth, quiet operation and prevents seizing or jamming even after years of frequent use, significantly extending the hinge’s service life and reducing maintenance requirements.

3. Heavy-Duty 6-Point Mounting

With six strategically placed mounting holes, this hinge distributes weight and stress evenly across the mounting surface. This configuration provides exceptional stability and resistance to pull-out, making it ideal for heavy, large, or frequently opened doors.

4. Generous Size and Robust Construction

Measuring 150mm in length, this hinge provides ample surface area for secure mounting and excellent load distribution. The thick steel construction ensures it can withstand the rigors of industrial use without bending or failing.
