Classic Methods for Measuring Staircases, Stairwells and Handrails
Measuring Tape
You often use a tape measure because it's the most common and accessible method. It is used to measure the horizontal and vertical dimensions of steps, risers and stringers. Although this method is simple, it can be prone to human error, particularly on complex staircases.
Bubble Level and Ruler
You can also use a spirit level and a ruler to check the angles and levels of the different parts of the staircase. These tools often complement the tape measure. They ensure that the staircase is correctly aligned and level, guaranteeing the safety and comfort of users.
Templates and Walking Templates
These tools are essential for winding or spiral staircases, where the dimensions vary from step to step. Templates allow you to reproduce the exact shapes and angles required.
Inclinometer
The inclinometer measures the angle of slope of the staircase. This is crucial for ensuring the comfort and safety of the staircase.
Our technique: Laser scanning
At 3D Scan Bat, we use an advanced laser scanning method to measure a staircase, stairwell or handrail. This technique offers unrivalled accuracy and captures the smallest details using a point cloud.
Advantages of Laser Scanning
- Accuracy High The laser scanner captures millions of points, creating an extremely accurate 3D model of the staircase.
- Speed Measuring is quick, reducing the time spent on site and minimising potential interruptions.
- Detail You capture the smallest details, allowing you to better understand and document the structure of the staircase.
Illustration with a Point Cloud
We have illustrated our comments with an image of a point cloud of a wooden staircase with a metal handrail. This point cloud highlights the accuracy of our survey, even on complex structures.
Limitations and solutions
Reflective Materials
Some materials, such as iron or stainless steel, reflect the laser's rays, creating a haze and reducing the accuracy of the reading. However, we have developed techniques to minimise this inconvenience, such as :
- Scanning with Little Light You reduce the ambient brightness, which reduces reflections and improves the quality of the reading.
Conclusion
Laser scanning remains an excellent method for measuring a staircase, handrail or stairwell, particularly when the surfaces are made of wood or masonry. For non-glossy metal surfaces, we get good quality readings. However, we do not recommend this technique for glass, mirror or shiny metal surfaces. Thanks to our innovative solutions, we overcome some of the challenges associated with measuring reflective materials, guaranteeing optimum accuracy.
