Stone stair steps are widely used in various buildings because of their beauty, durability and easy maintenance, but anti-slip design is a key factor to ensure their safety. The following are the key points of stone stair steps becoming anti-slip design, including material selection, surface treatment and design details.
1. Material selection
Choosing the right stone is the first step in anti-slip design. Different stones have different anti-slip properties. The following are several common stones and their anti-slip properties:
Granite: It has high anti-slip performance, low water absorption and strong wear resistance. There are more common colors and textures to choose from, suitable for indoor and outdoor stairs.
Marble: It is beautiful and generous, but it has a high water absorption rate and relatively poor anti-slip performance. It needs to undergo special anti-slip treatment.
Limestone: It has a soft texture, high water absorption rate, and average anti-slip performance. It is suitable for stairs in dry environments.
Sandstone: It has a rough surface and good natural anti-slip performance, but it has a low hardness and is easy to wear.
2. Surface treatment
Surface treatment is an important means to improve the anti-slip performance of stone stair steps. The following are several common surface treatment methods:
Flamed surface: The stone surface is treated by high-temperature flame to form a rough concave and convex texture to increase friction. Suitable for outdoor stairs and humid environments.
Sandblasted surface: Use a high-pressure sandblasting machine to form uniform tiny pits on the stone surface to increase anti-slip performance. Suitable for indoor and outdoor stairs.
Polished surface: Although the polished surface stone is smooth, it can be treated to increase the surface micro-texture and improve the anti-slip performance. Suitable for stairs with high requirements for indoor decoration.
Axe surface: Use an axe to chop out traces of varying depths on the stone surface to form a natural anti-slip texture. Suitable for outdoor and humid environments.
3. Design details
Design details are also crucial to the anti-slip performance of stone stair steps. The following are some key design points:
Step depth: The appropriate step depth can ensure that the foot has enough support area and reduce the risk of slipping.
Skirting height: The right skirting height can prevent your feet from hitting the edge of the step when going up and down the stairs, improving safety.
Grain direction: The texture of the step surface should be parallel to the walking direction to increase friction and anti-slip performance. Avoid using vertical textures as they may cause your feet to slide.
Drainage design: Stairs in outdoor or humid environments should be designed with drainage ditches or grooves to quickly drain accumulated water and reduce the risk of slipping.
Edge treatment: The edge of the step should be rounded to avoid injuries caused by sharp edges and increase anti-slip performance.
The anti-slip design of stone stair steps involves many aspects such as material selection, surface treatment, design details and regular maintenance. Through scientific and reasonable design and careful maintenance, the anti-slip performance of stone stair steps can be significantly improved to ensure the safety of users.
