Stair Types & Construction
Concrete zigzag stairs, also known as “dogleg” stairs, are a popular choice for their space-saving design and distinctive visual appeal. The zigzag shape, with turns at angles, allows the stairs to change direction while keeping the footprint compact. These stairs are ideal for smaller homes or spaces where a traditional straight stairway wouldn’t fit.
Step-by-Step Guide to Building Concrete Zigzag Stairs
1. Planning and Measurements
Before beginning any construction project, precise measurements and planning are essential.
Measure the Total Rise: The total rise is the vertical distance from the ground level to the upper floor. This determines the number of steps.
Calculate Step Height and Tread Depth: In general, the height of each step should be between 7" to 8" (175 mm to 200 mm), while the tread depth (the horizontal part you step on) should be between 10" to 12" (250 mm to 300 mm). You’ll need to divide the total rise by your step height to get the number of steps, and divide the total horizontal distance (run) by the tread depth to determine how much space the stairs will take.
Determine the Zigzag Pattern: Zigzag stairs have turns that require accurate layout planning. The number of turns and the angle between them will influence the layout and space required.
2. Build the Formwork
Constructing the Forms: To pour concrete for the steps, you need a solid formwork (frame) that holds the concrete in place. Start by constructing wooden forms along the calculated rise and run of each step. The forms should be strong enough to withstand the weight of the concrete, so use high-quality plywood or lumber.
Form the Zigzag Shape: For the zigzag pattern, you'll need to cut and assemble forms in such a way that each turn is accounted for. The forms should be built according to the angle and step measurements you’ve planned.
3. Pour the Concrete
Mix the Concrete: For stair construction, it’s important to use a strong, durable concrete mix. A typical mix would consist of 1 part cement, 2 parts sand, and 3 parts gravel, with water added until the mixture reaches a pourable consistency.
Pouring the Concrete: Begin by pouring concrete into the first section of the forms (the first flight of steps), filling each step carefully. Use a trowel to smooth the surface and ensure the steps are level. Once the first section is done, move on to the next, ensuring the correct angle and continuity of the zigzag pattern.
Let the Concrete Cure: After pouring, allow the concrete to cure for at least 24-48 hours. This curing period is crucial for the concrete to reach its full strength.
4. Remove the Forms and Finish
Once the concrete has set and cured, carefully remove the wooden forms. You may need to smooth out edges and fill in any gaps or imperfections with additional concrete.
Add Texture: If desired, you can add a non-slip texture to the surface of the steps, such as by using a broom to lightly drag across the wet concrete before it fully hardens.
Polish or Paint: For a more refined look, you can polish the concrete or paint it with a durable concrete paint.
Aluminium and glass stair railings are a modern and elegant choice, providing safety while maintaining a light, airy look. The combination of aluminium for the structure and glass for the balustrades offers a sleek, minimalist style that works well in contemporary interiors. Here's how to install them:
Step-by-Step Guide to Installing Aluminium and Glass Stair Railings
1. Measure the Staircase
Determine the Length of the Railing: Measure the total length of your stairs to ensure you have enough materials for the railing. Include measurements for the top and bottom landings, as well as any intermediate posts.
Height of the Railing: The standard height for a stair railing is between 36" to 42" (91 to 106 cm). Measure the desired height from the surface of the stairs, ensuring it is consistent along the entire staircase.
2. Prepare the Aluminium Posts
Cut the Posts to Size: Aluminium posts are typically installed at the start, end, and at regular intervals along the staircase for support. Use a saw designed for metal or a hacksaw to cut the posts to the desired height.
Install Base Plates: Secure the base plates of the aluminium posts at the designated locations along the stairs. These base plates will anchor the posts to the floor or the edge of the stairs. Use a drill to pre-drill holes for bolts or screws.
3. Install the Aluminium Rails
Attach Horizontal Rails: Once the vertical posts are in place, install the horizontal rails that will hold the glass panels. These can be either top-mounted or bottom-mounted, depending on your design preference. Use screws or brackets to attach the rails securely to the posts.
Level the Rails: Ensure that the horizontal rails are perfectly level and aligned before tightening them into place.
4. Install the Glass Panels
Fit the Glass: Carefully place the glass panels between the aluminium posts. Glass panels typically come pre-cut to fit your measurements. Ensure the glass is securely held in place by the rails, with protective rubber or silicone spacers to prevent direct contact with the metal, which can cause scratching or damage.
Secure the Glass Panels: Use clamps or U-channel brackets to hold the glass securely. These clamps will allow for a tight grip while leaving a slight gap for expansion. Some glass systems use a silicone adhesive to bond the glass to the aluminium frames, offering additional stability.
Check for Stability: Once all the glass panels are in place, double-check that the railing system is secure and the glass is properly seated. Ensure there is no wobbling or movement.
5. Finishing Touches
Clean the Glass: After installation, thoroughly clean the glass panels to remove any dust or smudges. Use a glass cleaner and a soft cloth to ensure a streak-free finish.
Touch Up the Aluminium: If needed, touch up any areas of the aluminium posts or rails with a matching paint or powder coating for a consistent look.
Building concrete zigzag stairs and installing aluminium and glass stair railings is a rewarding project that can enhance the functionality and aesthetic of your space. The concrete stairs offer a durable, space-saving solution with a distinctive design, while aluminium and glass railings provide a modern, transparent look that adds sophistication without obstructing light. By following the steps outlined above, you can create a stylish, safe, and functional staircase that will stand the test of time.
Metal floating stairs are an iconic and modern design choice, offering a sleek, minimalist aesthetic that enhances any space. Their “floating” look—where the steps appear to be suspended in mid-air—gives an airy, open feeling to interiors. This design is especially popular in contemporary and industrial-style homes, creating a striking visual statement while maintaining a sense of openness.
Building metal floating stairs involves a combination of precision craftsmanship and structural integrity. In this guide, we will walk you through the step-by-step process to help you design and construct your own floating stairs with a metal framework.
Metal floating stairs are a type of staircase that combines metal supports (usually steel or aluminum) with floating steps, which are typically made of wood, concrete, or glass. The “floating” effect is achieved by securing the steps to the side or central support structure without the use of visible vertical risers or supporting columns.
This creates the illusion that the steps are suspended in mid-air, providing a visually striking look while maintaining a sense of openness and space. Metal is a popular material choice for floating stairs because of its strength, durability, and sleek modern look.
1. Design and Planning
Before you start constructing, precise planning is essential to ensure the staircase is both functional and safe. Consider the following:
Measure the Space: The first step is to take accurate measurements of the area where the stairs will be installed. Measure the total height (rise) from the lower floor to the upper floor and the total horizontal distance (run) for the stairs.
Determine the Step Dimensions: Based on the rise and run, determine the number of steps needed and their dimensions. For comfortable use, the height of each step (riser) should be between 7" to 8" (175 mm to 200 mm) and the tread depth (the horizontal part of the step) should be around 10" to 12" (250 mm to 300 mm).
Decide on the Material for Steps: Metal floating stairs typically use a combination of a metal frame and other materials for the steps. Common options include:
Wood: Solid wood steps offer a warm, natural look that contrasts well with the industrial feel of metal.
Concrete: Concrete provides a more industrial, heavy-duty aesthetic and works well with modern designs.
Glass: Glass treads can provide a more contemporary and transparent look.
Choose the Type of Support Structure: Floating stairs can be supported by a side beam, a central spine, or a combination of both. The support structure will determine how the steps are mounted and how they achieve the “floating” effect.
2. Fabricating the Metal Frame
The metal framework is the backbone of the floating stairs, providing the structural support needed to carry the weight of the steps. Typically, steel is used for the frame because of its strength and durability.
Cutting the Steel: Using steel beams (either square or rectangular tubing), cut the pieces to the required length for the stringers (the structural supports on which the steps rest). For side-supported floating stairs, you will need one or two long beams that run along the side of the steps. For central spine-supported stairs, a single, thick steel beam will run down the center, with steps attached on either side.
Welding the Frame: Using a welding machine, weld the steel beams together to form the stringers and any additional supports. This is a critical part of the process, as the frame must be strong and perfectly square to ensure the stairs are stable.
Reinforcing the Frame: Additional cross supports or brackets may be welded to ensure the frame is rigid and won’t warp over time. The metal frame needs to be able to bear the weight of the steps and the people using them.
3. Installing the Metal Frame
Once the frame is fabricated, it’s time to install it in the stairway opening.
Mount the Side Beam or Central Spine: Depending on the design, install the metal stringers along the side or center of the staircase. For side-supported stairs, the stringers should be securely attached to the wall or floor at the base. For central spine stairs, the spine should be fixed to the wall and the floor at the bottom.
Ensure Plumb and Level: Use a level to ensure that the frame is perfectly plumb (vertical) and level (horizontal). This is crucial for both the aesthetic and safety of the stairs. You may need to adjust the frame to ensure that each step sits evenly.
4. Attaching the Steps
Once the frame is in place, the steps themselves can be installed.
Prepare the Steps: Cut the treads (steps) to the desired size. If you're using wood, ensure that the pieces are properly sanded and treated to prevent damage. For concrete or glass steps, the fabrication process will differ.
Mount the Steps: The steps are mounted onto the metal frame using brackets, bolts, or welded supports. The treads are typically bolted to the side or top of the frame. For side-supported stairs, you will likely need to attach the steps to the metal frame using heavy-duty steel brackets.
For wood steps, screws or bolts are used to secure the steps into the metal frame.
For concrete steps, a more robust attachment method such as welding or bolting is needed.
For glass steps, custom supports are used to attach the glass securely to the frame, often with rubber or silicone to prevent direct contact with the metal.
Spacing Between Steps: Be mindful of the spacing between each step (riser height). Make sure it complies with building codes for safety.
5. Installing the Handrails and Guardrails
Safety is paramount when building stairs. Floating stairs typically include a handrail or guardrail to prevent falls and provide support.
Select the Material for the Railing: For a modern, industrial look, steel or stainless steel is a popular material for the handrail. For a more transparent look, glass railings can be used with a metal frame.
Install the Posts: Start by securing the posts for the handrail at regular intervals along the staircase. These posts are usually mounted to the side or at the landing of the stairs.
Attach the Handrail: The handrail is then fixed to the posts, either by bolting or welding. The railing should be at a comfortable height, usually between 34” to 38” (85 cm to 95 cm) from the stair tread.
Add Glass Panels (Optional): If using glass guardrails, install tempered glass panels between the posts, ensuring that the panels are secured tightly to prevent any movement.
6. Finishing Touches
Sanding and Polishing: If you're using wood for the steps, sand the surface to achieve a smooth finish. For metal, make sure the surface is free from any sharp edges or rough spots, and polish the metal to give it a clean, shiny look.
Painting and Sealing: Consider painting the metal parts of the staircase with a high-quality, durable finish to prevent rust and corrosion. Powder coating is a popular method for a long-lasting finish. For wood steps, apply a protective sealant to prevent moisture damage.
Lighting (Optional): To enhance the floating effect, consider installing LED strip lights along the underside of the steps. This adds a dramatic, modern touch and increases safety by illuminating the steps.
Building metal floating stairs is a rewarding and complex project that can completely transform the look and feel of a space. The key to success lies in precise planning, careful material selection, and proper construction techniques. Whether you opt for a side-supported or central-spine design, metal floating stairs add a sleek, contemporary edge to your home or commercial space.
Building timber stairs can be a rewarding project that enhances the aesthetic and functionality of any home. Timber stairs offer a natural, warm feel, blending well with both traditional and modern interiors. Whether you're upgrading an old staircase or building a new one, creating timber stairs from scratch is a manageable DIY project for those with some woodworking experience. This step-by-step guide will walk you through the process of designing, cutting, and installing your very own timber stairs.
Before you start building timber stairs, it’s essential to plan your project carefully. Proper design will ensure that the stairs are not only functional and safe but also aesthetically pleasing.
Determine the Staircase Dimensions:
Total Rise: Measure the total vertical distance from the lower floor to the upper floor where the stairs will end.
Total Run: Measure the horizontal distance from the base to the top of the staircase.
Step Height (Riser): Divide the total rise by the number of steps you want. A comfortable riser height is typically between 7” to 8” (175 mm to 200 mm).
Step Depth (Tread): The tread should be between 10” to 12” (250 mm to 300 mm) to provide a comfortable step size.
Choose Your Timber:
For timber stairs, you’ll need high-quality hardwood that can withstand wear and tear. Popular options include oak, maple, beech, or walnut. These woods are sturdy, long-lasting, and can be finished beautifully with stains or varnish.
Select a Staircase Style:
Straight Stairs: The simplest design, where the steps go straight up without any turns or landings.
L-Shaped or U-Shaped Stairs: These designs have turns or landings, adding complexity and style to your staircase.
Spiral Stairs: This is a more advanced design that saves space and offers a unique look.
Before you begin building your timber stairs, gather all the necessary materials and tools.
Materials:
Timber for Treads: Plan for durable hardwood planks.
Timber for Stringers: Typically, thicker timber such as 2x12 boards.
Nails or Screws: Galvanized or timber-specific screws for fastening.
Wood Glue: For additional strength.
Wood Finish or Stain: To seal and finish the wood, enhancing its durability.
L-brackets (optional): For extra support.
Tools:
Measuring Tape: For accurate measurements.
Circular Saw or Table Saw: To cut the timber to the correct size.
Drill and Drill Bits: For making holes for screws.
Miter Saw: For cutting angles and corners.
Level: To ensure the steps are even and aligned.
Wood Plane: To smooth the wood edges.
Clamps: To hold the timber in place while you work.
Hammer or Screwdriver: To secure the pieces together.
Stringers are the structural backbone of your stairs and will support the treads (the horizontal parts of the steps). They are cut at an angle to accommodate the rise and run of each step.
Measure and Mark:
Using your total rise and total run measurements, mark out the locations for the treads along the timber for the stringers. A stringer calculator can be helpful in determining the precise measurements for the rise and run of each step.
Cut the Stringers:
Using a circular saw or jigsaw, carefully cut the timber stringers along the marked lines. Ensure your cuts are straight and even, as the stringers will serve as the primary support for the stairs.
After cutting, use a level to check that the stringers are even and aligned.
The treads are the horizontal steps you will walk on, and the risers are the vertical parts that sit between each tread.
Cutting the Treads:
Using your measuring tape, cut the tread pieces from your hardwood timber. Each tread should be slightly longer than the total width of the stringers (usually about 1 inch on either side to overhang the stringers).
The depth of each tread should be between 10” to 12” for optimal comfort.
Cutting the Risers:
Risers are cut from the same timber as the treads but are typically thinner. Measure and cut the riser pieces to fit between each tread.
Smoothing the Edges:
Use a wood plane to smooth the edges of the treads and risers, ensuring they fit together neatly and have no rough edges.
Now that you have your stringers, treads, and risers cut, it’s time to assemble the stairs.
Attach the Risers to the Stringers:
Start by securing the risers to the stringers using wood screws or nails. Apply wood glue to the edges of the risers before fixing them in place for extra strength.
Attach the Treads:
Next, attach the treads to the stringers, ensuring they align properly with the risers. Use wood screws to secure each tread to the stringers, and make sure there is no movement when pressure is applied.
Check for Level:
As you secure the treads and risers, continually check that the structure is level. This ensures that the stairs will be even and safe to use.
Add Support (Optional):
For added stability, especially for longer flights of stairs, you may want to install L-brackets or additional support beams along the underside of the stringers.
Once the structure is assembled, you can focus on finishing the timber stairs to enhance both their appearance and durability.
Sand the Surface:
Use sandpaper or an orbital sander to smooth the entire surface of the stairs. This will remove any rough patches or imperfections and create a smooth, polished finish.
Stain or Paint:
Apply a wood stain or paint to the stairs to enhance the timber’s natural beauty or match your home’s interior. Make sure to use a wood finish that is durable and suitable for high-traffic areas.
If you prefer a natural wood look, apply a clear varnish or lacquer for protection.
Install Railings:
To finish off the stairs, install railings for safety. You can opt for timber railings, or go for a metal or glass design for a modern twist.
Clean Up:
Finally, clean up any dust or debris from the sanding process, and make sure all tools are properly stored.
