The baserail is a critical component in the construction of a staircase. They provide support, stability, and aesthetic cohesion to the railing system. Anchoring the balusters and aligning them with the handrail ensures that the staircase is both safe and visually appealing. The proper placement of the base rail along the stringer, on landings, or at the start of the staircase is essential for a well-functioning and attractive staircase design.
Use of a Base Rail:
- Supporting Balusters:
The primary function of the baserail is to support the balusters, which are the vertical spindles that connect the base rail to the handrail. The balusters are inserted into pre-drilled grooves or slots in the base rail, keeping them securely in place and evenly spaced. This ensures that the railing system is stable and safe. - Providing Stability:
By anchoring the balusters, the base rail adds structural stability to the entire railing system. It prevents lateral movement of the balusters, ensuring that the handrail remains strong and capable of withstanding pressure from people leaning on it or grabbing it for support.
Placement of a Base Rail:
- Along the Stringer:
Sitting upon the top of the stringer is the usual placement of a base rail in traditional staircases. Running diagonally from the bottom to the top of the staircase, the baserail sits upon the stringer. Aligned with the incline of the stairs, the base rail follows the same angle as the stringer. This placement ensures that the balusters are positioned vertically and are securely anchored between the base rail and the handrail. - On Landings and Balconies:
When placing base rails on landings or balconies, we position baserails directly on the floor, parallel to the landing & handrail. The rails below the handrail, known as balusters, rest on the base rail for lower support. The handrail, located above, provides the upper support. This setup helps create a continuous railing system that extends around the landing or along the edge of the balcony.
