Bi-fold hinges are a unique type of mechanical bearing that diverges from standard hinges in their functionality. Unlike the typical two-leaf design, bi-fold hinges consist of three leaves, two knuckles, and two pins, allowing for a dual-direction swing. This means that surfaces such as doors equipped with bi-fold hinges can be opened by either pushing or pulling, offering a more versatile range of motion.

The construction of bi-fold hinges enables them to provide this multi-directional rotation. The two outer leaves attach to the respective surfaces, while the central leaf acts as the pivot point for the swinging motion in both directions. This design not only enhances convenience but also maintains the simplicity of installation, mirroring the process used for standard hinges.

Material selection for bi-fold hinges is crucial, especially in environments prone to moisture. Stainless steel is a common choice due to its resistance to corrosion, attributed to its chromium content, which forms a protective layer against rust. This makes stainless steel bi-fold hinges a reliable option for areas with high humidity.
