Piano Hinges

Piano hinges, also known as “continuous hinges,” extend the entire length of a door or flap. These 304 grade stainless steel hinges are welded on making them a good solution for industrial equipment and other sheet metal applications that need to stand up in corrosive environments.

Sugatsune offers a wide variety of hinges crafted in stainless steel ensuring durability that will last for many years of consistent wear and use.

What’s Unique About Continuous Hinges?


The strength of piano hinges is that they offer smooth and continuous rotation along the entire length resulting in a consistent and stable movement. Stress points along the length of the continuous hinge are also minimized by its design adding to its longevity and being welded on, it is more difficult to tamper with or remove, enhancing the security of the door or lid. 

Best of all, our hinges are designed to provide smooth motion and are available between 12 to 71 inches long and can be simply cut to fit your specific applications.
