How to Choose the Right Floor Spring for Commercial Glass Doors
Commercial glass doors are widely used in office buildings, shopping malls, hotels, airports, restaurants, hospitals, and luxury residential projects. While the glass door itself attracts attention, the floor spring hidden beneath the floor is the key component that ensures smooth operation, safety, and durability.
Selecting the right floor spring can significantly improve door performance, reduce maintenance costs, and extend the lifespan of the entire door system. This guide explains everything architects, contractors, builders, and project managers need to know when choosing a floor spring for commercial glass doors.
What Is a Floor Spring?
A floor spring is a concealed hydraulic door control device installed below the floor surface. It controls the opening and closing movement of a door while maintaining a clean and elegant appearance.
Unlike traditional overhead door closers, floor springs are designed to support heavier doors and allow double-action opening, making them ideal for frameless glass door systems.
Key Benefits of Floor Springs
- Concealed installation
- Elegant architectural appearance
- Adjustable closing speed
- Double-action opening
- Heavy-duty load capacity
- Long service life
- Smooth and quiet operation
Because of these advantages, floor springs are commonly used in modern commercial and architectural projects.
Why Choosing the Right Floor Spring Matters
A floor spring is one of the most important components in a glass door system. An undersized or low-quality floor spring can result in:
- Difficult door operation
- Door misalignment
- Hydraulic oil leakage
- Increased maintenance costs
- Safety risks
- Reduced product lifespan
Choosing the correct floor spring ensures reliable performance even in high-traffic environments.
Key Factors to Consider When Choosing a Floor Spring
1. Door Weight
Door weight is the first factor to evaluate.
Different floor spring models are designed to support specific door weights.
| Door Weight | Recommended Floor Spring |
|---|---|
| Up to 100kg | Standard Duty |
| 100kg – 150kg | Medium Duty |
| 150kg – 250kg | Heavy Duty |
| Above 250kg | Extra Heavy Duty |
For shopping malls, hotels, and office entrances, heavy-duty models such as BTS80 floor springs are often recommended.
Always verify the manufacturer’s load capacity specifications before purchasing.
2. Door Width
The width of a glass door directly affects the amount of force applied to the floor spring.
As door width increases, the required closing force also increases.
Typical recommendations:
- Door width under 1000mm
- Door width between 1000mm and 1200mm
- Door width above 1200mm
For oversized commercial entrances, select a floor spring specifically designed for wide-door applications.
3. Traffic Volume
Commercial environments often experience thousands of opening and closing cycles every day.
Examples include:
- Airports
- Shopping malls
- Hotels
- Hospitals
- Government buildings
- Corporate offices
For these applications, choose a floor spring that has been cycle-tested for durability.
High-quality floor springs are commonly tested for more than 500,000 opening and closing cycles.
4. Door Material
Floor springs can be used with:
- Frameless glass doors
- Aluminum doors
- Wooden doors
- Steel doors
Different door materials have different weight distributions and operational requirements.
Always ensure the selected floor spring is compatible with your door type.
5. Hold-Open Function
Many commercial projects require doors to remain open at a specific angle.
Typical hold-open positions include:
- 90°
- 105°
- 120°
Hold-open floor springs are commonly used in:
- Shopping centers
- Hotels
- Conference halls
- Public buildings
However, some fire-rated applications may prohibit hold-open functions. Always check local building regulations.
6. Adjustable Closing Speed
A quality floor spring should provide independent adjustment for:
- Closing speed
- Latching speed
- Backcheck function
These adjustments improve:
- User comfort
- Safety
- Door control
- Long-term performance
Adjustability is especially important in commercial buildings where environmental conditions can vary.

Floor Spring vs Door Closer
Many project managers compare floor springs with traditional door closers.
| Feature | Floor Spring | Door Closer |
|---|---|---|
| Appearance | Concealed | Visible |
| Double Action Opening | Yes | Usually No |
| Glass Door Compatibility | Excellent | Limited |
| Heavy Door Support | Excellent | Moderate |
| Architectural Aesthetics | Premium | Standard |
For frameless glass doors and high-end commercial projects, floor springs are generally the preferred choice.
