Self closing door hinge

Types of self closing door hinge

A self closing door hinge is a hinge that automatically draws the door to a close and holds it in place when the door is released. Self-closing door hinges are essential for safety and security because they ensure that doors are closed, especially those leading to fire exits.

These hinges come in various types, depending on the requirements of the doors on which they will be used. Some of the commonly used self-closing door hinges are as follows:

• Spring Hinges

  Spring hinges are also called door spring hinges. They are commonly used as self-closing door hinges because they are versatile and available in varying sizes and finishes. They are used for both interior and exterior doors. Spring hinges are fitted with a coiled spring inside the hinge pivot that provides tension. When the door is opened, the spring expands. As soon as the door is released, the spring contracts, pulling the door towards the closed position.

• Automatic Door Closers

  Automatic door closers are also known as hydraulic door closers. They are specifically designed for heavy doors and high-traffic areas. These self-closing door hinges are made with a strong metal casing that houses a hydraulic cylinder and a piston. When the door is opened, hydraulic fluid moves through a controlled passage. When released, the fluid moves back, closing the door smoothly and quietly.

• Concealed Hinges

  These are also known as hidden hinges. They are popular as self-closing door hinges for cabinet doors. They are designed to be invisible when the door is closed. Concealed hinges are made with a metal cylindrical body that contains the pivot point and spring. They are installed inside the door and frame, allowing for a clean and seamless appearance. When a concealed hinge is properly fitted, it provides an excellent self-closing action and a smooth, quiet operation.

• Pivot Hinges

  Pivot hinges are used for heavy doors like those used in commercial or industrial spaces. They are installed at the top and bottom of the door's corners. Pivot hinges are designed with a top pivot that is mounted on the door frame and a bottom pivot that is attached to the floor. They are constructed with heavy-duty materials like steel or brass to support the weight of the door. Pivot hinges provide smooth and controlled closing.

• Ball Bearing Hinges

  These hinges are not explicitly self-closing but can work with door closers to ensure the door is securely closed. They are made with ball bearings that reduce friction and enable smooth operation. They are used for heavy doors in commercial settings.

Self-closing door hinges are available in different materials, such as stainless steel, brass, and zinc. Each material has its own advantages. Stainless steel is often preferred because it is resistant to rust and corrosion. This makes it suitable for areas with high moisture levels.

• Weight Capacity:

  It is important to consider the weight of the door when choosing a self-closing hinge. Heavier doors may require hinges that can support more weight. Most manufacturers indicate the weight capacity of the hinge on the product description. Check the weight capacity list to ensure the hinge is suitable for the weight of the door.

This is because it will allow the contractor to make the necessary adjustments to fit the user's requirements.

• Closing Mechanism:

  Self-closing door hinges can come in different closing mechanisms. For example, hydraulic, spring-powered, and ball bearing. Hydraulic hinges provide smooth and quiet closing. Spring-powered hinges are more traditional but may produce more noise. It's important to consider the closing mechanism to ensure it fits the needs and requirements of the user.
