Door hinges are movable connecting elements that connect a door to the door frame and allow it to rotate.

They ensure stability, smooth opening and closing and secure fastening of the door.

Below you will find the function, structure and types of door hinges, an overview of their use and information on maintenance and care:

How door hinges work:

When the door is opened and closed, the door leaf rotates around the axis of the door hinge. Depending on the design, the hinge can perform a simple rotation or a more complex movement (e.g. with concealed hinges).

Structure of door hinges:

1. Hinge parts: Two or more plates that are connected to the door and frame.
2. Rotation axis (pin, pin or ball bearing): This element enables the movement.
3. Bearing: Slide bearing or ball bearing for low-friction rotation.
4. Additional functions: Cushioning, adjustability or burglary protection.

Here are the most important aspects to look out for when buying door hinges:

When buying door hinges, various technical, functional and economic aspects must be taken into account. The wrong choice can lead to malfunctions, rapid wear and tear or even safety risks.

• Before purchasing door hinges, you should answer the following questions:
• Is the hinge intended for interior, exterior, fire-rated or specialty doors?
• How heavy is the door? Does the door hinge have to bear special loads?
• Is a 90° opening sufficient or is a 180° or swing function required?
• Does the door require additional burglary protection?
• Will the door hinge be used indoors or under extreme conditions (moisture, heat)?
• The following types of door hinges are available:
• Screw-on hinges allow easy installation. They are visible on the door and frame.
• Drill-in hinges have a discreet appearance. They are mostly used for room doors.
• Concealed door hinges allow invisible installation for a modern design.
• Sealing hinges are particularly sturdy. They are suitable for metal doors and industrial applications.
• Fire protection doors require certified fire protection hinges (e.g. in accordance with DIN 18272).
• Soundproof doors require special hinges with a sealing function.
• Swing doors are fitted with swing door hinges with opening on both sides.
• Heavy-duty doors require robust heavy-duty hinges with a high load-bearing capacity.
• The load-bearing capacity of a door hinge must match the weight of the door. The heavier the door, the more stable and resilient the hinge should be.
• It is advisable to always include a safety margin in the load capacity to prevent premature wear.
• Stainless steel or galvanized door hinges are recommended for outdoor use.
• Modern door hinges offer a combination of adjustability and damping for optimum convenience.
• The door hinges should be attached precisely to avoid jamming or squeaking.
• Professional purchasing should take standards and certificates into account:
• The DIN 18272 standard: fire protection door hinges.
• The DIN EN 1935 standard: Testing the load-bearing capacity of door hinges.
• CE marking: safety in accordance with EU directives.
• ISO certification: Quality control for durable products.
• Certified products are mandatory, especially for fire doors.
• Pay attention to the price-performance ratio when purchasing. High-quality door hinges save maintenance costs.

Paying attention to these points will ensure efficient, economical and sustainable purchasing of door hinges!
A well-planned purchase saves costs in the long term and increases the security and durability of the doors.
