Floor Springs: The Hidden Strength Behind Smooth and Secure Door Movement

When it comes to door hardware, most people focus on handles, locks, and hinges. But if you've ever walked through a glass door that closed effortlessly behind you without a sound, chances are it had a floor spring installed. Often hidden beneath the surface, floor springs are essential components in modern architecture, ensuring smooth, controlled, and secure door operations—especially in commercial and high-traffic environments.

In this blog, we’ll explore what a floor spring is, how it works, where it’s used, and why it’s a smart investment for homes and businesses alike. And of course, if you’re looking to buy the best quality floor springs online, That Hardware Store has you covered.

What is a Floor Spring?

Floor springs are installed in the floor directly below the door to close it. They help control the door's movement, allowing it to open smoothly and close automatically and silently. Unlike overhead closers, floor springs are concealed, making them ideal for aesthetically pleasing spaces like glass doors, office entries, showrooms, malls, and hotels.

These closers are especially popular with heavy or frameless glass doors, where both function and form are equally important. Floor springs support both single and double-action doors, meaning the door can swing in both directions and return to the closed position automatically.


How Does a Floor Spring Work?

A hydraulic mechanism powers a floor spring. Here's a breakdown of its components and functions:

  • Hydraulic Cylinder: Controls the speed at which the door closes to prevent slamming.

  • Cam Shaft: Transfers rotational force from the door movement into the spring mechanism.

  • Adjustable Valves: Allow fine-tuning of the closing and latching speed.

  • Cover Plate: Offers protection and easy access for maintenance.

When someone pushes or pulls the door, the cam rotates, compressing the spring. The spring returns to its original shape as the force is released, bringing the door back to its closed position.

Benefits of Installing Floor Springs

1. Aesthetic Appeal

Because floor springs are concealed beneath the floor, they don’t interfere with the visual appeal of modern interiors, especially when used with frameless glass doors or minimalist office designs.

2. Improved Door Control

With adjustable speed settings, you can ensure your door never slams shut or remains half-open—offering a safe and professional experience for users.

3. Durability and Strength

Heavy-duty floor springs handle high-traffic doors. Whether it’s a steel door in a factory or a 10 mm glass door in a hotel lobby, floor springs ensure long-term durability with minimal maintenance.

4. Accessibility and Convenience

Because they allow bi-directional movement, doors with floor springs are easier to access for individuals with disabilities or while carrying items—ensuring compliance with modern accessibility standards.

5. Safety and Security

Controlled closing ensures the door shuts fully, helping maintain internal temperature, reduce noise, and enhance security—especially in commercial buildings or retail spaces.


Common Applications of Floor Springs

  • Glass Doors in malls, offices, and showrooms

  • Main Entry Doors of commercial spaces and hotels

  • Fire-rated Doors in commercial and industrial premises

  • Metal or Timber Doors in hospitals, schools, and airports

  • Double-Action Doors in busy cafes, restaurants, and lobbies

Types of Floor Springs Available

At That Hardware Store, we offer a curated selection of high-quality floor springs suited for various door sizes and functions. The main types include:

1. Single Action Floor Springs

Ideal for doors that open in only one direction. These are typically used in commercial spaces like offices and corridors.

2. Double Action Floor Springs

Perfect for doors that swing in both directions. Common in hotel lobbies, restaurants, and other busy environments.

3. Heavy-Duty Floor Springs

Engineered for industrial doors or large glass panels, these are designed to handle greater weight and higher cycles per day.

How to Choose the Right Floor Spring

When selecting a floor spring, consider the following:

  • Door Weight and Width: Each floor spring model supports a specific weight and width range.

  • Type of Door: Glass, wooden, or metal doors may need different models and fittings.

  • Traffic Frequency: For high-traffic areas, opt for heavy-duty models.

  • Closing Force Required: EN-rated standards indicate the power of the spring (e.g., EN 2–5). Choose the correct rating to avoid under- or over-powered closers.

Not sure which one to pick? Our experts at That Hardware Store are always ready to assist.

Installation and Maintenance Tips

While floor springs offer superior performance, correct installation is key. Here are some quick tips:

  • Ensure level flooring before installation.

  • Use the correct spindle size for your door thickness.

  • Check alignment of the pivot and door center line.

  • Regularly inspect the hydraulic fluid and cover for wear or damage.

If you're unsure, it's always best to hire a professional installer to guarantee safety and longevity.
