Continuous Hinge

A continuous hinge, also known as a piano hinge, is a long hinge that runs along the entire length of a door, lid, or panel.

This design helps distribute the load evenly across the full hinge length, improving durability and reducing the risk of door sag compared to standard separate hinges.

Continuous hinges are commonly used in applications such as electrical cabinets, furniture cabinets, storage boxes, lids, folding tables, and various industrial equipment.

Typical technical specifications of continuous hinges include:

- Length: usually manufactured in long bars such as 1.8 m, 2 m, or 3 m and can be cut to the required size.
- Width when fully opened: commonly ranges from 20 mm, 25 mm, 30 mm, 40 mm, 50 mm to 75 mm or 100 mm.
- Leaf thickness: typically 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, up to 2.0 mm depending on load requirements.
- Pin diameter: generally from 1.5 mm to 4 mm to ensure a strong rotating joint.
- Opening angle: can reach approximately 270° to 360° depending on installation and design.

Thanks to their ability to distribute force evenly and provide high durability, continuous hinges are widely used in applications requiring stability and long-term reliability.
