1830 × 25 × 1mm Florentine-Bronze Steel Piano Hinge

This 1830mm steel piano hinge, also known as a continuous hinge, measures 25mm wide when fully open and 1mm thick. Its Florentine-bronze plated finish gives the steel a darker, traditional bronze-coloured appearance for visible cabinet and joinery installations.

Piano hinges were originally developed to hinge the long keyboard covers and lids fitted to pianos. They are now commonly used in cabinet making, furniture, boxes, cases, access panels and other joinery requiring support along an extended hinged edge.

Continuous hinges are also used in some security-conscious door and panel designs because the hinge connection and fixing positions extend along the joint. This product has no declared security classification, load rating or fire-door certification, so suitability must be assessed for each installation.

Supplied as one complete 1830mm hinge length. It may be cut to a shorter required length using suitable metal-cutting equipment.

What is a Florentine-bronze finish?

Florentine bronze is a decorative dark-bronze plated finish applied over the steel base material. It provides an aged, traditional bronze-coloured appearance without making the hinge solid bronze.

Why use a continuous hinge?

A continuous hinge extends along the hinged edge instead of concentrating the connection at several separate hinge positions. This can help distribute movement along a long lid, door or panel and maintain alignment across its length.

Cutting and installation

1. Measure and mark the required finished length carefully.
2. Use suitable metal-cutting equipment and personal protective equipment.
3. Remove sharp edges and metal swarf after cutting.
4. Position and align the complete hinge before marking fixing points.
5. Select fixings appropriate for the substrate, hinge holes and application.
6. Test alignment and movement before final tightening.

Fixing screws are not confirmed as included. Do not advertise included fixings unless the physical product has been checked.
