TYPES OF HINGES NAMES USES BUYING GUIDE
Hinges are among the most overlooked parts of any building or piece of furniture. They hold doors, cabinets, gates and lids in place, carry their weight for thousands of cycles, and decide whether movement feels smooth or stiff. Pick the wrong one and you get sagging doors, squeaks, rust or early failure.
This guide covers the main types of hinges, with their names, uses, mechanisms, materials and grades, plus a practical buying checklist.
How a Hinge Works: The Basic Mechanism
Almost every hinge follows the same basic hinge mechanism. Two plates, called leaves, are joined by a central pin that passes through rolled sections called knuckles. One leaf fixes to the moving part, such as a door, and the other to the fixed part, such as a frame. The pin lets the leaves rotate against each other, which creates the swing.
Variations on this idea give us the different types of hinges below. Some add bearings to cut friction, some hide the mechanism inside the door, and others use springs or a pivot point in place of a side-mounted pin.
Types of Hinges and Their Uses
1. Butt Hinge
The butt hinge is the most common of all hinge types. Two rectangular leaves are recessed into the door edge and frame, so they sit flush when closed.
Uses: Interior and exterior doors, wardrobes, windows, and general woodwork. It is the default choice for most residential doors.
2. Ball Bearing Hinge
This is a butt hinge with ball bearings between the knuckles. The bearings reduce friction and wear, so the door swings quietly and carries more weight.
Uses: Heavy doors, entrance doors, and high-traffic commercial buildings such as offices, schools, and hotels.
3. Concealed Hinge
A concealed hinge is hidden when the door is closed, which gives a clean, uncluttered look. Many models allow adjustment in three directions, so you can fine-tune alignment after installation.
Uses: Modern interior doors, flush doors, kitchen cabinets, and wardrobes.
4. Pivot Hinge
A pivot hinge rotates the door around a vertical axis at the top and bottom, with no side-mounted knuckles. The door's weight is carried at the floor or lower pivot point, so even very large doors can open easily.
Uses: Oversized timber doors, glass doors, and architectural entrances.
5. Piano Hinge (Continuous Hinge)
A piano hinge runs the entire length of the door or lid. Spreading the load along the whole edge gives high strength and prevents sagging.
Uses: Toolboxes, storage chests, lockers, heavy cabinet doors, fold-down tables and display cases.
6. Spring Hinge
A spring hinge has a built-in spring that closes the door automatically. The spring tension can often be adjusted to control closing speed.
Uses: Fire doors, bathroom and kitchen doors, garden gates, and any door that must close by itself.
7. Strap Hinge
A strap hinge has long, decorative leaves that extend across the door face. They distribute weight over a wider area and give a traditional, rustic appearance.
Uses: Barn doors, timber gates, sheds, garage doors and farmhouse-style entrances.
8. T-Hinge
A T-hinge has one short leaf and one long leaf that form a T shape. It fixes onto the surface without the need for mortising.
Uses: Fence gates, shed doors, shutters and light outdoor structures.
9. Flush Hinge
A flush hinge has two staggered leaves that fold over each other, so no recess is needed. It gives a slim profile and quick installation.
Uses: Lightweight interior doors, cabinets, and furniture.
10. Security Hinge
A security hinge uses fixed pins or locking studs, so the door cannot be removed even if the pin is hammered out.
Uses: Main entrance doors, outward-opening doors and commercial premises.
11. Cabinet and Furniture Hinges
Furniture uses several specialised hinges, including cup (European) hinges, overlay and inset hinges, soft-close hinges and glass door hinges. They are designed for lighter loads, with adjustment features and smooth, quiet closing.
Uses: Kitchen cabinets, wardrobes, vanities, display units and glass shelving.

Hinge Materials: What Are They Made Of?
The material often matters as much as the type.
Mild steel: Strong and economical, but it needs a protective coating or paint to resist rust.
Brass: Attractive and naturally corrosion-resistant, popular for decorative doors and furniture.
Aluminium: Light and rust-free, suited to lighter doors and windows.
Stainless steel: Strong and resistant to moisture and staining. Grade 304 suits general indoor and outdoor use, while grade 316 offers extra protection in coastal, marine and chemical environments.
Cast iron: Heavy and durable, often used for antique-style gate and door hardware.
For bathrooms, kitchens, balconies, and seaside locations, stainless steel is usually the best long-term choice.
Understanding Hinge Grades
You may see hinges described by grade, which indicates how much use and weight they can handle.
ANSI/BHMA grades (common in the US): Grade 1 is heavy-duty and suited to high-traffic commercial use, Grade 2 is medium duty, and Grade 3 is light duty for residential doors.
EN 1935 (common in Europe and the UK): Hinges are rated across a numbered scale based on durability, load capacity, corrosion resistance, and fire suitability, and higher grades are generally required for fire doors.
Always check the grade and any fire certification against the requirements of your project and local regulations. Residential doors rarely need top-grade hinges, but commercial and fire-rated openings usually do.
How to Choose the Right Hinge: A Buying Guide
Use this checklist before you buy:
Door or lid weight. Heavy doors need ball-bearing, pivot, or continuous hinges. Light furniture doors can use flush or cabinet hinges.
Number of hinges. Most doors need three. Tall, wide, or heavy doors may need four.
Location. Use stainless steel or coated hinges in damp, coastal, or outdoor areas.
Visibility. Choose concealed hinges for a seamless look, or decorative strap hinges where the hardware is part of the design.
Opening direction and angle. Check whether the door opens inward or outward, and how far it needs to swing.
Security needs. Outward-opening and entrance doors benefit from security hinges.
Size and thickness. Match hinge height, width and plate thickness to the door size.
Finish. Satin, polished, black, antique and brass finishes should match handles, locks and other fittings.
Standards and certification. Look for recognised grades and, for fire doors, the right fire certification.
Supplier reliability. Consistent quality, accurate specifications and dependable delivery matter, especially for bulk or project orders.
Common Hinge Problems and Fixes
Squeaking: Lubricate the pin, or switch to ball-bearing hinges for heavy use.
Sagging door: Tighten screws, use longer screws that reach the frame, or add a hinge.
Rust and staining: Replace with stainless steel or coated hinges in humid areas.
Door not closing properly: Adjust concealed hinges or add shims behind the leaf.
Worn pins: Replace the hinge early before damage spreads to the door or frame.
Installation Tips
Mark hinge positions accurately and cut clean, correctly sized recesses. Use screws of the right length and material, and fit all hinges on the same line so the door hangs straight. A common layout puts the top hinge about 150 mm from the top of the door and the bottom hinge about 225 mm from the bottom, with a third hinge in the middle. For heavy, fire-rated or expensive doors, use an experienced carpenter.
Final Thoughts
The right hinge depends on the weight of the door, how often it is used, where it is installed, and how it should look. Butt hinges handle most everyday doors, ball bearing and piano hinges suit heavy use, concealed and pivot hinges deliver modern style, and spring, strap and security hinges cover specific needs. Choose the right type, material, and grade, and your doors and furniture will work smoothly for years.
