What’s Unique About Continuous Hinges?


Heavy-duty piano hinges provide unmatched stability thanks to their ability to deliver smooth, consistent rotation throughout their length. Unlike traditional hinges with concentrated stress points, piano hinges spread stress evenly, minimizing wear and extending their lifespan. Their design enhances security, as they’re welded on, making them harder to tamper with or remove. Our hinges are available in lengths ranging from 12 to 71 inches, offering flexibility for various applications.

Each hinge can be designed to the exact size needed to fit your specific project requirements. Additionally, they ensure smooth, reliable motion for heavy-duty use across doors, lids, or panels. Whether your application is industrial, commercial, or residential, our selection ensures durability and functionality.

Wide Range of Applications


Piano hinges offer strength and a sleek, modern look that architects favor for contemporary designs. Engineers rely on their flexibility to suit custom projects. At the same time, the corrosion-resistant satin and plain finishes ensure durability in interior and exterior settings, even in moisture-prone or high-movement environments. These hinges are ideal for residential or high-traffic commercial spaces, combining style, reliability, and performance.

  • Residential Furniture: Used in foldable tables, cabinets, storage boxes, and hidden compartments for durability and smooth functionality.
  • Commercial Doors and Partitions: Ideal for high-traffic areas like office doors, restroom partitions, or storage rooms for stability and strength.
  • Toolboxes and Equipment Cases: Common in industrial-grade tool chests, medical equipment cases, and custom storage solutions.

Our piano hinges undergo rigorous cycle testing and quality controls to ensure lasting durability. This ensures they deliver reliable performance across various applications. Their easy installation makes them an essential component for functional and stylish designs.
