Spiral staircases are often chosen by many families to design for houses with a modern style and high aesthetics. However, homeowners need to pay attention to some of the following issues to ensure functionality when using.
Stairway ladder surface size
Unlike straight stairs, spiral stairs have a shape that narrows towards the central axis. Therefore, to ensure safety and comfort for users, it is necessary to consider designing the overall diameter of the stairs to reach a minimum of 1.5m to 2m.
In which, the width of the step should reach from 20 - 25cm, no less than 10cm at the narrowest point near the rotating axis. This size ensures that the user's feet have enough contact area, minimizing the risk of missing steps.
Ensure static height
Because the steps are stacked on top of each other vertically, it is necessary to pay attention to the distance from each side of the steps to limit injuries due to impacts when moving. Static height does not need to reach at least 2m at any location on the stairway.
Handrail and railings structure
For spiral stairs, the handlebars also need special attention to help maintain balance when moving. The handlebar system needs to be designed seamlessly, without interruption from the starting point to the ending point, with a standard height of 90cm to 100cm.
In particular, the distance between the bars (cones) of the railing must not be more than 10cm to ensure maximum safety, especially for families with young children.
Surface materials and stair lighting
Homeowners should also consider choosing materials for the stair surface, for example, shiny wood or granite, so limit use because it is very easy to slip and fall. At the same time, it is also necessary to consider installing sliding splints at the edges of steps or using specialized carpets.
In addition, the lighting system also needs to be arranged along the staircase axis or lighted up each step for users to conveniently go up and down, reducing steps in low-light conditions on the stairs.
