Floating Staircase Manufacturer

Floating staircase, also known as a suspended staircase, is a modern and visually striking architectural feature where the steps appear to “float” in mid-air with no visible support.

This effect is achieved through innovative engineering and design, where each tread is securely attached to a wall or central spine, creating the illusion of unsupported steps.

The treads of a staircase can be made from a variety of materials, including wood, metal, glass or stone, offering a wide range of design possibilities to match any interior style.

Despite their delicate appearance, suspended stairs are actually very sturdy and safe, capable of supporting considerable weight.

Known for their sleek, modern look, floating staircases are made up of several basic components:

– Cantilevered Treads
The treads are the horizontal steps you walk on. In a floating staircase, these treads are cantilevered, meaning they are only fixed at one end.

– Hidden Supports
In some designs, a hidden central spine or support beam runs through the center of the staircase, providing the necessary support while keeping the steps visually floating.

– Stringers (optional)
Stringers can be side mounted, center mounted, or even completely hidden within the wall.

– Railings and Balusters
Common materials include glass, metal, and wood. Glass railings are particularly useful for floating staircases because of their transparency, which enhances the floating effect.

– Handrails
Handrails can be mounted on the wall or integrated with the railing system. Wall-mounted handrails are often used to maintain the open feel of the staircase.

– Support Brackets and Fixings
These are essential for securing the treads to the wall or central pillar. They must be strong enough to support the weight and use of the staircase.

– Anti-slip Surfaces
To prevent slips, especially on glass or polished stone treads, use an anti-slip coating or insert. This can be a textured surface or a clear coating that provides grip without changing the appearance.

Suspended stairs create the illusion that the steps are “floating” in mid-air with no visible support.

1. Treads
Anchor points: One end of each tread is usually anchored to a load-bearing wall or hidden central pillar, while the other end is unsupported, creating a floating effect.
Hidden supports: The supports are hidden in the wall or in the tread itself so that they are not visible to the naked eye, thus maintaining the illusion of floating steps.

2. Structural engineering
Load-bearing wall: The wall to which the tread is anchored must be a load-bearing wall capable of supporting the weight of the staircase and the additional load from foot traffic.
Central spine: In some designs, a central spine runs through the center of the staircase, supporting each tread from below. This spine is often narrow or recessed so that it is not visible.

3. Material selection
Strong materials: The treads are made of a material that is strong enough to support weight at a single point of attachment, such as hardwood, metal, or reinforced glass.
Reinforcement: The material is often reinforced with an internal steel frame or rod to ensure stability and strength while maintaining a slim profile.

4. Minimalist Design
Open Risers: Floating stairs often have open risers (vertical spaces between treads), which enhances the feeling of openness and lightness.
Transparent Railings: Glass railings or minimalist metal railings are often used to provide security without obstructing the visual effect of the suspension.

5. Hidden Masts
Hidden Masts: When masts are used, they are often hidden within the wall or designed to be minimalist and unobtrusive. This allows the focus to be on the floating treads.
Side-Mounted Beams: In some cases, side-mounted beams that blend in with the wall or treads can be used to provide additional support while being hidden from view.

There are many different materials used for staircases, but to maintain the beauty and structural integrity of a suspended staircase, we recommend the following materials:

– Wood
Hardwood: Oak, walnut, maple, and teak are popular for their durability and natural beauty. These woods can be finished in a variety of ways, including staining, painting, or oiling, to enhance their appearance and longevity.

Faux Wood: Faux wood treads offer stability and resistance to warping, making them a practical choice for suspended staircases. They consist of a hardwood veneer on a composite core, giving the look of real wood with extra strength.

– Metal
Steel: Stainless steel or powder-coated steel is often used for treads and brackets because of its strength and modern aesthetic. Steel can be formed into thin, sturdy brackets to maintain the illusion of suspension.

Aluminum: Aluminum is lighter than steel, resistant to corrosion, and suitable for both indoor and outdoor applications. It has a sleek, modern look and can be anodized or powder-coated in a variety of colors.

– Glass
Tempered Glass: Tempered glass is used for treads, railings, or banisters, providing a clear, airy feel that enhances the suspended effect. Tempered glass is strong and shatter-resistant, ensuring safety.

Laminated glass: Laminated glass consists of multiple layers of glass and plastic interlayers, which provide additional safety and strength. Even if it breaks, it stays together, reducing the risk of injury.

– Stone
Marble: With a luxurious and elegant appearance, it is a popular choice for high-end residential and commercial projects. Marble treads are strong and durable, but require regular maintenance to prevent staining and scratching.

Granite: Known for its durability and wear resistance, granite is a practical choice for indoor and outdoor suspended staircases. It comes in a variety of colors and patterns, adding a unique touch to each staircase.

Artificial stone: Made of crushed stone and bonded with polymer resins, artificial stone combines the beauty of natural stone with additional durability and uniformity.

– Composite materials
Fiberglass: Lightweight, strong, and moisture-resistant, fiberglass is a great choice for outdoor suspended stairs. It can be molded into a variety of shapes and painted in different colors.

High-density polyethylene (HDPE): This durable plastic material is impact-resistant, moisture-resistant, and UV-resistant, making it suitable for indoor and outdoor use.

Our designers and factory craftsmen have extensive experience in stair design and construction, and they are either talented or skilled. Engineers can ensure that the stair design meets all structural requirements, including load-bearing capacity and anchoring methods.

At the manufacturer of the stair, we ensure that the treads are deep and wide enough to ensure safety and comfort. Typical requirements are a tread depth of at least 10 inches and a riser height of no more than 7.75 inches. All treads and risers should be uniformly sized to prevent tripping hazards. The tread surface should use a material or coating that provides adequate traction to prevent slips.

Install railings and handrails on at least one side of the staircase. The height from the nose of the tread to the top of the railing should be between 34 and 38 inches. The gap between any railing should not exceed 4 inches to prevent falls and meet child safety standards. Guardrails are also recommended for stairs that are 30 inches above the ground.

Based on our experience in stair customization over the years, floating stairs have certain advantages over traditional stairs:

– Aesthetic Appeal
Modern Design: Floating stairs have a sleek, modern look that enhances the overall aesthetic of a space. The minimalist design can be a focal point for residential and commercial interiors.
Visual Lightness: The open, airy structure of a floating stair creates a sense of spaciousness, making the room feel larger and more open.

– Space Efficiency
Under-Stair Utilization: Floating stairs often leave the space under the stairs empty, which can be used for additional storage space, seating area.
Light Flow: The design of a floating stair allows light to pass through, improving the distribution of natural light in the room, which is particularly useful in smaller or darker spaces.

– Customization Flexibility
Material Diversity: Floating stairs can be built with a variety of materials, including wood, metal, glass, and stone, allowing for greater customization to suit different design preferences and functional needs.
Design Options: A variety of shapes and configurations (straight, L-shaped, U-shaped, spiral) can be customized to suit specific spaces and styles.

When implementing a floating stair design, you need to pay attention to and avoid the following problems,

– Inadequate structural support
Underestimating load requirements: Failure to correctly calculate load-bearing capacity can lead to structural failure. Ensure that the anchor system and treads are designed to support the expected weight, including dynamic loads.

Improper anchoring: Inadequate or incorrect anchoring to the wall or central spine can compromise stability.

– Improper material selection
Weak materials: Choosing materials that are not strong enough to support the structure can cause premature and severe wear on the stairs. Choose durable materials such as hardwood, steel, tempered glass or artificial stone.

Incompatible finishes: Choosing finishes that do not match the intended use can cause maintenance issues.

– Lighting Overview
Inadequate lighting: Inadequately lit stairs can be dangerous and reduce the visual impact of the stairs. Integrate lighting solutions to improve visibility and aesthetics.

Glare issues: Avoid placing lights in locations that will create glare or harsh shadows on the stairs. Properly positioned lighting can improve safety.

– Inadequate planning and testing
Not conducting a trial installation can lead to unexpected problems during installation. A trial installation helps to identify and resolve any problems before final installation.

Calculate the total rise (vertical distance from the lower floor to the upper floor) and divide by the desired rise per step (typically between 7 and 8 inches). For instance, if the total rise is 96 inches and the rise per step is 8 inches, you will need 12 steps (96 ÷ 8 = 12).

Calculating the number of steps for a floating staircase isn’t difficult. There are a few key points to consider to ensure your staircase is both functional and comfortable.

– Measure the total height
Total height: The total height is the vertical distance from the lower floor to the upper floor.
Tools needed: Use a tape measure to measure the height from the lower floor to the upper floor.

– Determine the ideal riser height
Standard riser height: Generally, comfortable riser heights for stairs range from 7 inches (178 mm) to 7.75 inches (197 mm).

– Calculate the number of steps
Number of steps = Total riser height / Required riser height

– Determine tread depth
Comfortable tread depth: Standard tread depth (the horizontal portion of the step) is generally about 10 inches (254 mm) to 11 inches (279 mm) for a comfortable footing.

– Calculate the total run
Formula: Total run = Number of treads * Tread depth
Note: The number of treads is generally one less than the number of risers.

– Consider Headroom and Stair Width
Headroom: Make sure there is enough headroom above the staircase for safe passage, typically at least 80 inches (2032 mm) from the tread surface to the ceiling above.
Width: The width of the staircase should be convenient for use, with a minimum width of about 36 inches (914 mm) for residential stairs.

Suspended stairs are a beautiful, modern statement piece in any setting, but like all architectural features, they require proper care to remain beautiful and safe.

– Regular Cleaning
Dusting: Regularly dust the treads and railings with a soft cloth or duster to prevent dust buildup.
Vacuuming: Use a vacuum cleaner with a brush attachment to remove dust and debris from hard-to-reach areas, such as between treads and at wall anchors.
Wiping: Clean the treads with a damp cloth and a mild detergent appropriate for the material.

– Material-Specific Care
Wood:
Polishing: Regularly polish wood treads with a suitable wood polish to maintain their shine and protect the surface.
Protect: Apply a protective sealer every few years to protect against scratches and moisture.
Metal:
Rust-Proofing: Check for signs of rust, especially in areas with high humidity. Clean with a metal cleaner and apply a rust inhibitor if necessary.
Polishing: Use a metal polish to keep the treads and railings shiny and rust-free.
Glass:
Cleaning: Use a glass cleaner and a microfiber cloth to remove fingerprints, stains, and dust.
Check: Check regularly for chips or cracks and address any damage promptly to prevent further problems.
Stone:
Sealing: Apply stone sealer to prevent stains and moisture.
Cleaning: Use a pH-neutral cleaner to avoid damaging the stone surface.

– Safety Inspection
Check anchors and supports: Check the integrity of anchors and supports regularly to ensure they are secure and show no signs of wear or damage.
Tighten fixings: Tighten any bolts or screws regularly to maintain the stability of the staircase.
Check railings and handrails: Make sure all railings and handrails are securely attached and in good condition. Tighten any loose fittings and repair or replace any damaged parts.

– Preventive Measures
Use carpets or mats: Place carpets or mats at the bottom and top of the stairs to absorb dust and reduce wear on the treads.
Anti-skid mats: Consider adding anti-skid mats to the treads to prevent slips, especially if the stairs are frequently used by children or the elderly.
Avoid heavy blows: Avoid throwing heavy objects on the treads to prevent dents, scratches, or cracks.
