When it comes to building a spiral staircase, dimensions are crucial to ensure it fits the space and is safe to use. Here are some important dimensions to consider:
- Diameter: The diameter of a spiral staircase is the sum of its treads and central column. It determines the amount of space it will occupy. A smaller diameter is more suitable for spaces with limited floor space.
- Height: The height of each tread or step is an important dimension that determines the ease of climbing up or down the staircase. The height should be consistent throughout the entire staircase to avoid any tripping hazards and ensure user safety.
- Tread Depth: The tread depth is the horizontal distance between the centerline of the staircase and the forward edge of the step. It should be deep enough to provide a secure foothold and ensure comfort when climbing up or down.
- Rise: The rise of a step is the vertical distance between the top of one tread and the top of the next. It should be consistent throughout the entire staircase to ensure user safety and comfort.
- Handrail Height: The handrail height is an important dimension that ensures user safety. It should be at a comfortable height for users to grip and provide support when ascending or descending the stairs.
Before building a spiral staircase, it is important to consult with a professional to ensure that you correctly measure every dimension. A professional can also help you choose the right materials and design for your specific needs and budget.
