When you’re navigating a bustling shopping mall or catching a flight at an airport, escalators are a part of your journey you barely notice. But have you ever wondered about the grooves on the steps? They’re not just for aesthetics or to make the escalator look fancy. These grooves serve essential purposes that prioritize safety, functionality, and efficiency.
Let’s delve into the reasons behind this seemingly simple design feature and uncover how it plays a crucial role in keeping escalator passengers safe.

The Function of Grooves on Escalator Steps
At first glance, the grooves on escalator steps may appear to be a way to prevent slipping. While they do offer traction, their primary purpose is far more technical and essential.
1. Smooth Transition with the Comb Plate
When escalator steps reach the top or bottom, they align perfectly with a comb-like plate called the comb plate. The grooves on the steps fit seamlessly into this comb plate, ensuring a smooth transition for passengers.
This alignment has two major benefits:
- Prevents Items from Getting Stuck: The grooves minimize the chances of objects—like shoes, bags, or clothing—getting trapped between the steps and the floor.
- Improves Operational Safety: Without these grooves, foreign objects could jam the escalator, potentially causing it to malfunction or pose a hazard to passengers.
2. Water Drainage and Slippery Surface Prevention
Another critical purpose of these grooves is to manage spills. If liquids such as water or drinks end up on the steps, the grooves help channel the liquid away, preventing it from pooling on the surface.
By reducing the risk of slippery steps, the grooves play a key role in preventing accidents, especially in high-traffic areas where spills are more likely.
How the Comb Plate Works with Grooved Steps
The interaction between the grooved steps and the comb plate is a marvel of engineering.
Fitting Like Puzzle Pieces
The grooves ensure that the steps align snugly with the comb plate. This design allows the steps to retract and extend seamlessly as they cycle through their movement.

Added Safety Against Jamming
Imagine an escalator step without grooves—small items like coins, shoelaces, or dirt could easily get stuck in the gap between the step and the landing. This could not only damage the escalator but also pose safety risks to passengers. The grooves and comb plate combination effectively eliminates this issue.
Safety Brushes: The Unsung Heroes of Escalator Design
While the grooves handle the horizontal plane of the escalator, have you noticed the small brushes running along the sides of the steps? These safety brushes might seem insignificant, but they’re a vital component of escalator safety.
1. Preventing Snagging
Safety brushes are strategically placed to keep items like long coats, scarves, bags, and shoelaces from getting caught between the escalator steps and the skirt panel (the side of the escalator).
2. Triggering a Reflex Response
Interestingly, these brushes have a psychological function too. When a person feels the brush against their leg or belongings, they instinctively move away from the edge. This simple design feature helps reduce the likelihood of accidents.

3. Mandatory Safety Standards
In 2004, British and European safety standards made these brushes a mandatory feature for escalators. This highlights their importance in ensuring passenger safety and minimizing risks.
The Bigger Picture: Why These Features Matter
Escalators are used by millions of people daily, and safety is non-negotiable. Every design element, no matter how small, works toward preventing accidents and ensuring a smooth experience for riders.
The Role of Grooves in Preventing Accidents
Without grooves, items could easily get lodged in the machinery, causing the escalator to malfunction. This could lead to sudden stops, tripping hazards, or worse—serious injuries.
The Importance of Safety Brushes
Similarly, without safety brushes, loose clothing or long items could snag in the escalator’s moving parts. The consequences of such accidents could be severe, making these brushes an indispensable feature.
The Engineering Genius Behind Escalators
Escalators might seem straightforward, but their design involves meticulous planning and engineering. The grooves, comb plates, and safety brushes are just a few of the many details that contribute to their functionality.

A Seamless Blend of Safety and Efficiency
These design features not only protect passengers but also ensure that the escalator operates smoothly and reliably. Whether it’s managing water spills or preventing mechanical jams, every element is crafted with care.
Why You Should Appreciate the Design
Next time you step onto an escalator, take a moment to notice the grooves and brushes. These small, often-overlooked features are there to protect you, making escalators one of the safest and most convenient modes of transport in public spaces.
An Everyday Machine with Extraordinary Design
From the way the grooves align with the comb plate to the way safety brushes guide passengers away from danger, escalators are a testament to thoughtful engineering.
Conclusion: The Grooves That Keep You Safe
The grooves on escalator steps are more than just a design element—they are a vital safety feature. By ensuring smooth transitions, preventing objects from jamming the mechanism, and reducing slip risks, they make escalators safer and more efficient.
Paired with safety brushes, these features create a system that protects millions of riders every day. So, the next time you hop on an escalator, take a moment to appreciate the ingenuity beneath your feet. Small details, after all, can make the biggest difference.
