Different subtypes of glass door floor springs and floor springs for door closers made for doors of diverse materials consist of the following:

• Single Action 

1. Compatible with wooden, aluminium, and glass (framed or frameless) doors.
2. The door swings in one direction (inward or outward) and is often a non-handed or specific-handed model.
3. Varies by size, e.g., 60 kg, 80 kg, 100 kg.

• Double Action (Bi-Directional)

1. Compatible with wooden, aluminum, and glass (usually frameless) doors.
2. The door swings in both directions (inward and outward) and returns to a centre closed position.
3. Varies by size, typically 80 kg, 120 kg, 150 kg, up to 300 kg for heavy-duty.

• Hold-Open (with Back-Check)

1. Compatible with non-fire-rated doors (wooden, glass, metal)
2. It includes an adjustable mechanism to hold the door open at a specific angle (e.g., 900, 1050, or 1200) and usually a hydraulic back-check (cushioning) to prevent the door from slamming open.
3. Varies by size—medium to heavy-duty, e.g., 80 kg - 250 kg.

• Non-Hold-Open

1. Compatible with fire-rated and standard doors
2. Does not include a hold-open function. So, it’s essential for the fire doors to ensure they close and latch automatically.
3. It varies widely by size; it is often available in sizes EN 1-6.

• Adjustable Closing Force (e.g., EN 2-4 or EN 3-6)

1. Compatible with various types of wooden, glass, and metal doors.
2. Allows the installer to adjust the closing force/power size (EN standard) to match the door weight and width on-site and offers flexibility.
3. Covers a range of capacities, e.g., EN 4 is typically for doors up to 100 kg / 1100 mm width.

• Heavy-Duty/Super Heavy-Duty

1. Compatible with large, oversized, or high-traffic doors (e.g., banks, public entrances).
2. Having a larger body and components that are designed for maximum durability. Has a high load-bearing spindle.
3. Can handle high capacity, e.g., 180 kg, 250 kg, 300 kg.

• Concealed/Overhead Floor Spring

1. Compatible with metal or wooden doors.
2. It is a variant where the mechanism is installed within the overhead transom of the door frame, offering a concealed look without breaking the floor.
3. The capacity varies widely; they are often available in sizes EN 1-6.

The key design and functional characteristics consist of:

• Adjustment Valves: Almost all modern hydraulic floor springs feature adjustable valves to independently control two key speeds:

1. Closing Speed: The speed at which the door moves from its maximum opening angle (e.g., 1300 down to about 150).
2. Latching Speed: The final speed of the door from the last 150 or 200 to the fully closed position, ensuring that the door closes securely into the latch or frame.

• Body & Mechanism: Typically feature a cast iron body set within a zinc-plated cement box for installation.  The mechanism uses a spring compressed by a worm wheel in hydraulic fluid.
• Aesthetics/Finish: The visible components are the cover plate and the pivot eyelet, usually available in materials like Satin Stainless Steel (SSS), Polished Stainless Steel (PSS), or other metallic finishes to blend with surrounding hardware.
• Compatibility:

1. Glass Doors: Require additional patch fittings (top patch, bottom patch, and pivot) to connect the frameless glass panel to the floor spring and the top pivot.
2. Framed Doors: Connect directly to the floor spring spindle using a bottom pivot accessory.

When selecting a floor spring, the maximum door weight and maximum door width are the most critical factors to ensure proper function and longevity.
