What Makes Long Hinges Unique?

A striking feature of hinges, or piano hinges, is their length. They typically span the entire length of the object to which they are affixed. This design distributes the load more evenly, ensuring durability and a smoother range of motion. Not limited to pianos, their use extends to many everyday items such as toolboxes, storage chests, and even some vehicle doors.


What Materials Are Piano Hinges Made From?

Piano hinges are typically made of durable metals like steel, stainless steel, brass, and sometimes even aluminum. These materials provide robustness and longevity, ensuring the hinge can bear considerable weight over prolonged periods. This durability is a key reason why piano hinges are used in applications requiring sturdy, reliable support.
