    L-shape

    stair

    L- shaped or 90 degree turn staircase

    Compared to I- and U-shaped stairs, L-shaped stairs are the most common. L-shaped stairs are the most compact in the solution and enable economical use of the building’s interior. L-shaped stairs are an important element of room interior design. Compared to I-shaped stairs, there are more options for different designs. More difficult to measure and install than an I-shaped staircase. Requires previous stair installation experience. L-shaped stairs are more expensive than I-shaped stairs, but cheaper than U-shaped stairs.

    L-shaped stairs can be solved as a fan shaped tread staircase or with a landing or a stair platform. A fan shaped tread staircase requires less interior space than a staircase with a landing. However, the space under the stairs is more spacious and has a greater use in the case of a staircase with a landing. The staircase with a landing provides an opportunity for a safer staircase solution and, if necessary, facilitates a rest stop for the user of the stairs when moving up the stairs. A fan shaped tread staircase allows the user with a normal health to move faster between floors. A staircase with a landing is easier to measure and install, it is cheaper than the equivalent fan shaped tread staircase. The fan shape tread staircase contributes to minimalist modern room design. When choosing the shape of the stairs, it is definitely worth consulting an architect, interior designer or STAIR24 specialists to find the most suitable solution.

    Stringer

    Stringers of the Staircase

    The stringers of the staircase are the main supporting structure of the staircase, on which the treads rest. Stringers can be traditional with a linear edge shape, in which case they are called classic type stringers, or with a stepped edge shape, in which case they are referred to as modern type stringers. For unfinished, lacquered, oiled, or stained stairs, the stringer material is laminated wood made from a wood species chosen by the customer. For painted stairs, the stringer material can be either laminated wood or laminated wood covered with HDF material.

    Classic Type Stringers

    In the case of classic type stringers, the treads are fixed between the stringers, into mortises processed into the sides. The joint between the tread and the stringer is made with a screw connection. Before installing the treads, the mortises are treated, which, in addition to strengthening the staircase construction, helps prevent creaking sounds caused by the movement of staircase components.

    Modern Type Stringers

    In the case of modern type stringers, the treads are supported by dowel joints on the horizontally processed upper edges of the stringers. For modern staircase stringers, the term “saddle stringer” is sometimes also used.

    Riser

    In the case of open staircases, the space between the treads is open or partially closed with a safety strip for security reasons. The safety strip can be chosen as an optional accessory. Safety strips are attached under the treads with screws. An open staircase is more affordable than a closed staircase and also allows better light distribution in the room. In many countries, the maximum gap between the treads is regulated.

    An important structural component of closed staircases are risers installed between the treads. Risers are typically finished in the same tone as the stringers and posts. If a covering paint is chosen for the risers, they are made from MDF board. However, if the risers are to be finished with lacquer, stain, oil, or left unfinished, they are made from laminated wood of the same species and quality grade as the treads. A closed staircase is structurally more rigid and capable of bearing a greater load than an open staircase. Additionally, a closed staircase can be used to create space divisions within a building if needed.

    Handrail and railing position

    The placement of stair handrails should be optimal for the comfort and safety of users. It is essential to consider the mobility of the staircase users and the national construction regulations in the specific country. It is important to decide whether the staircase needs one or two handrails and how to secure the handrails. As a standard, the handrail on the inner curve of the staircase is attached with balusters fixed to the stringer. The handrail on the outer curve is generally attached to the wall with handrail brackets. If the staircase is situated between walls, it can either be without handrails or have handrails attached to one or both sides with brackets. The height of the handrails is measured from the front edge of the tread to the top line of the handrail. The standard height for handrails at Stair24 is 900 mm.

    Materials and finishing

    Treads, Handrails

    When choosing materials for the steps and handrails, it’s important to consider their durability, ease of maintenance, and suitability for the interior style. Stair steps and handrails are typically manufactured from the same material and use a similar finish.

    Well hole shape

    UP

    Stairwell refers to the opening inside the ceiling structure where the stairs are positioned, forming the staircase. A well-functioning staircase with sufficient headroom requires an optimally sized stairwell. It is advisable to finalize the choice of staircase model, layout, and dimensions during the building design phase. Stairwells are typically either rectangular or L-shaped.

    Number of steps

    The number of steps must be optimal to ensure comfortable use of the staircase. Too few steps can cause discomfort, while too many can make using the staircase difficult. The formula used to calculate a comfortable staircase is 2H + B = 630 (where two times the rise height plus the tread depth should equal 630 or a value close to it). If there is not enough space for a comfortable staircase, the initial solution is to recalculate the staircase by reducing the number of steps. This staircase formula is universal and applicable for calculating the number of steps for any staircase. Monitor the parameters control bar above the staircase drawing; if the values are green, it indicates a comfortable staircase. In special circumstances, use the advice provided by our system to make decisions.

    Well hole railings

    Well hole railings Staircase barriers, or floor barriers, are crucial safety and design elements. Depending on the building layout, choices can be made regarding which sides of the staircase opening actually need barriers. The design of staircase barriers typically resembles the solution used for stair handrails. The height of staircase barriers depends on specific building regulations in each country and ranges from 900 to 1200 mm. Staircase barriers with a length of up to 3,500 mm can be manufactured without intermediate posts. The components of staircase barriers include the base rail, end posts, intermediate posts, balusters, and handrails.

    Child security gate

    Safety gates attached to the structure of the staircase allow the staircase to be used without closing off the stairway, minimizing risks associated with children or pets using the stairs. The safety gates can be installed to close off only the bottom, top, or both staircases. In our selection, you will find economically priced options like the white-colored Flexi variant with fixed profiles, or the Design variant executed to match the profiles and finish of the staircase railing. The safety gates can be installed separately from the staircase installation by the customer and can be easily removed later.

    Safety steps

    Tread risers provide the opportunity to reduce the open space between staircase steps in the case of an open staircase, ensuring maximum height to comply with building regulations when necessary, and minimizing risks associated with children or pets using the stairs.

    Ceiling cover plate

    As an optional accessory, it is possible to choose a ceiling cover plate for an open staircase. The cover plate is used to cover the upper edge of the landing between the stair stringers. There are two different ceiling cover plates available: one made from the same material and finish as the step, or one that matches the material and finish of the stair stringer.

    LED lights

    LED lighting on stairs serves both a design and practical function.

    Safety: LED lighting on stairs helps illuminate the steps and makes stair usage safer by reducing the risk of falls, especially at night or in dim lighting conditions.
    Directional lighting: LED lighting can be customized for various purposes, such as directional lighting on the steps or lighting on the stair handrail, which can help users grip the stairs more securely.
    Energy efficiency: LED lighting is more energy-efficient than traditional lighting solutions, helping to reduce energy consumption and save on electricity bills.


    In summary, LED lighting on stairs is a versatile solution that not only enhances stair safety but also adds aesthetic value. It provides energy-efficient and long-lasting illumination.

     

    Anti-slip protection

    Anti-slip protection on stairs helps reduce the risk of slipping and enhances stair safety. Anti-slip grooves on wooden stair treads and rubber strips are both effective ways to decrease slipping and increase safety. Each solution has its advantages:

    Rubber strips: Rubber anti-slip strips or pads installed on stair treads to improve grip and reduce slipping. Rubber strips are typically rubberized and offer a soft yet highly grippable surface, making stairs safer and more comfortable to use.

     

    Anti-slip grooves on wooden treads: Cuts or grooves machined into stair treads designed to provide better traction. These create textured areas on the tread surface that reduce the risk of slipping.

    Both anti-slip grooves and rubber strips are effective ways to reduce slipping on stairs, but the choice depends on preferences, stair material and design, and budget. Both options help increase stair safety and provide a more comfortable and secure user experience.

    Step covers

    MDF Step Covers

    When a staircase is installed in a building where renovation or construction work is being carried out, the structural parts of the stairs must be covered to prevent potential damage.

    To protect the steps, you can order a Stair24 step cover set, which consists of 2.5 mm thick MDF material, produced to the exact size of each step, along with adhesive tape.‎
    ‎
    Properly installed step covers allow sufficient protection of the stair treads from the effects of stepping in work shoes during construction work.

    The step covers must be removed within 30 days at the latest to avoid possible fading of the steps and to prevent the adhesive from the tape used for fastening the covers from being absorbed into the finish layer.
