What Does Tread Mean In Construction?
Tread refers to the horizontal portion of a stair assembly and is measured by its depth; this depth must be at least 10 inches to ensure a legal stair.
Treads are used in combination with risers, which are the vertical surfaces between each step, to form the overall shape and size of a staircase.
Generally speaking, treads provide more surface area for stepping on than risers, allowing people to easily traverse the stairs with greater stability compared to if only risers were present.
What Is The Purpose Of Stair Treads?
Stair treads are essential for any stairway as they protect the stairs from daily wear and tear by absorbing the impact of traffic and helping to reduce scuffs, scratches, and stains that can mar the surface.
Not only do they provide protection but they also improve safety by providing a slip-resistant surface, allowing people to traverse stairs with ease and confidence.
Furthermore, their use helps to prolong the lifespan of stairs, ultimately reducing maintenance costs in the long run.
How Long Is The Stair Tread?
Stair treads typically range between 8 and 10 inches in length, with 9-inch stair treads being the most common size; however, longer treads may be used on larger staircases.
To find the right-sized tread for your stairs, measure from the back of the step to the front to get an accurate measurement.
What Is The Minimum Tread For A Step?
The minimum tread for a step is 0.30m for outdoor stairs and between 0.28-0.35m for indoor stairs with a maximum of 0.18m riser height.
When the stairs cover a difference in the level of more than 2.50 m, an intermediate landing should be provided to ensure safe passage.
How Thick Should Treads Be?
The ideal tread depth on residential stairs should be no less than 10 inches with nosing and 11 inches without nosing, ensuring the treads are sufficiently thick enough to provide safe footing.
Maximum tread depth variation should also be kept under 3/8 of an inch for each step, as any variations outside this range can lead to potential tripping hazards.
It’s important to ensure tread depth is consistent in order to create a safe and secure staircase for those who use it.
What Is The Formula For Tread And Riser?
The formula for tread and riser is generally 7.5 inches for the riser height and 10 inches for the tread depth, resulting in a total of 17.5 inches per stair.
This rule-of-thumb formula for interior stairs is specified in Architectural Graphic Standards to ensure a safe and comfortable environment when ascending or descending.
It is important to adhere to the staircase proportions so that the user will not feel a sudden stride when climbing and enjoy a pleasant overall experience.
What Are The Different Types Of Stair Treads?
Stair treads are the horizontal surface of a step on which a person walks. The different types of stair treads include wood, glass, tile, composite, stone, and steel.
- Wood treads provide a natural finish that can be stained or varnished to create a unique look.
- Glass treads bring an elegant and modern touch while also providing transparency to the staircase design.
- Tile is practical and great at resisting wear and tear while also available in various colors and patterns.
- Composite treads are made from recycled materials such as sawdust, making them more affordable than other options.
- Stone treads are durable but heavy which can reduce noise transmission between floors in multi-level homes.
- Finally, steel is highly resistant to fire but can be slippery when wet.
