Spring Hinges: How to Choose, Install, and Maintain for Long-Lasting Performance

I. What is a Spring Hinge? Why is it Important?

A spring hinge is a piece of hardware that allows a door to close or remain in a specific position automatically. It is equipped with springs inside, and the opening and closing of the door is controlled by the force of the springs. This type of hinge is widely used on doors in homes, stores, offices, and more, for convenience and added security (e.g., to prevent the door from accidentally opening).

II. How Do Spring Hinges Work?

Basic Principle

When opening and closing the door, the spring is compressed or stretched, storing energy. When released, the spring releases the energy, allowing the door to return to its original position automatically.

Two Main Functions

1. Automatic Closing: Suitable for doors that need to be closed frequently (e.g., store doors).
2. Positioning Function: Allows the door to stop at a certain angle (e.g., hospital doors can remain open).

III. Common Types and Applicable Scenes

Select by Function

Type	Feature	Applicable Scenes
Automatic Closing Type	Automatically closes the door after letting go	Shop door, office door
Positioning Type	Fixed opening angle	Hospital doors, kitchen doors
Cushioning Type	Slows down and prevents collision when closing the door	Glass door, children’s room door

Select by Material

• Stainless Steel: Rust-resistant and durable, suitable for wet environments (e.g., bathrooms).
• Aluminum Alloy: Lightweight and cost-effective, suitable for indoor dry environments.
• Plastic: Low price but not weight-resistant, suitable for lightweight cabinet doors.

Select by Installation Method
