    I-shape

    stair

    I-shaped or straight stairs
    Compared to L shaped and U-shaped stairs, I-shaped stairs are the most affordable staircase solution. Also, the work related to measuring and installing I-shaped stairs is simpler and the risks are lower and can be performed even by a moderately experienced builder. I-shaped stairs are an important element of interior design, giving the opportunity to achieve a simple and minimalist style or by placing space in the middle to dominate the interior design.

    If the choice is in favor of an I-shaped staircase, the need for more space must be taken into account at the expense of interior space. Compared to alternative staircases, longer I-shaped stairs require more consideration of the safety of the stairs and the safety risks associated with the use of the stairs.
    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.
