Metal round staircase is an attractive and practical choice in duplex houses, villas and even small units; But beauty alone is not enough. If the standard dimensions of the round metal staircase for the home are not chosen correctly, the result can be a staircase that is tiring, unsafe or even dangerous to walk on. On the other hand, if everything is designed properly, the round metal staircase takes up little space and creates a smooth and safe movement.
Why is the standard dimensions of round metal stairs important for the house?
In this article, I will explain the standard dimensions of round metal stairs for home in simple but precise language: from the diameter and radius to the height of the step, the width of the floor, the proper slope, the railing and the bump distance. Also, I bring implementation and experience-oriented tips so that when ordering, you know exactly what you want and how to make the best decision. Throughout the text, some practical suggestions for basic ordering from Damavand Firouzkoh round staircase collection are provided to make your selection process faster and more reliable.
Basic definitions before selecting dimensions
Before entering the numbers, let's clarify a few key terms, because they will come in handy when calculating the standard dimensions of round metal stairs for your home:
- Floor to floor height: the finished distance from the floor of the lower floor to the finished floor of the upper floor.
- Riser or step height: the amount of height of each step.
- Stair floor or step depth: the part on which the foot is placed. In round stairs, the bottom of the stairs has different sizes at different points of the width.
- Diameter of the step: diameter of the overall circle of the stairs.
- Diameter of the central column: the diameter of the main pipe or column to which the stairs are connected.
- Line of movement: the common path of stepping on the stairs, which is usually considered close to the middle of the width of the stairs.
When we talk about the standard dimensions of round metal stairs for the home, we mean that the sizes are chosen so that the steps are comfortable and safe on the line of travel, not just on the narrow edge of the stairs.
Standard diameter of round metal stairs for home
One of the most important parts of the standard dimensions of round metal stairs for the home is the diameter of the stairs. The diameter determines how much space the stair takes up and at the same time how easily it can be walked on.
Experience oriented and common in residential buildings:
- Diameter about 120 to 150 cm: It can be used for limited spaces, but it becomes more difficult for two people to travel and it is more difficult to carry large items.
- Diameter about 160 to 200 cm: It is a very suitable choice for most duplex houses and villas, it has a good balance between taking up space and comfort.
- Diameter above 200 cm: It is suitable for larger spaces and feels more luxurious. it creates, commuting becomes smoother and the possibility of designing the floor of the stairs in the line of movement will be better.
Important note: If your home is a place of daily and frequent travel, choosing a diameter that is too small may become annoying in the long run. In order to choose the standard dimensions of the round metal staircase for the home, it is better not to see the diameter only based on the empty space; The way to carry things, the type of use and the number of family members are also important.
If you are hesitant to choose the diameter between the two options, Damavand Firouzkoh Round Staircase can recommend the best diameter according to the space and use of your home with a visit and accurate measurement, so that later you will not face the problem of narrow path or difficulty of commuting.
The standard height of each step (riser) in round metal stairs
The height of each step is one of the most key criteria in the standard dimensions of round metal stairs for the home. A high riser causes fatigue and pressure on the knee, a low riser also increases the number of steps, and in round stairs it may increase the rotation and length of the path.
In residential use, common and appropriate range:
- About 16 to 18 cm for the height of each step
If we want to look very practical, many comfortable stairs in houses have a riser of about 17 cm. Of course, the exact number depends on the height of your floor to floor. For example, if the floor to floor height is 300 cm, dividing by 17 gives approximately 18 steps. Then the designer may adjust the number slightly so that all the risers are the same and accurate.
Very important implementation point:
In round metal stairs, the difference of even a few millimeters in the height of the stairs can create a feeling of insecurity. So, one of the requirements of the standard dimensions of the round metal stairs for the house is that all the risers are made completely uniform.
In order for the risers to be executed precisely and evenly, it is suggested to leave the construction and installation to a team that has measuring tools and experience in implementing metal round stairs in residential projects. Damavand Firouzkoh Round Staircase is particularly sensitive to the precise implementation and uniformity of the height of the stairs.
The width of the stair floor in the round metal staircase (the actual measure on the line of movement)
The stair tread is a critical issue in a round staircase, because on the side near the central column, the stair tread narrows and on the outer side, it is wider. Therefore, when we talk about the standard dimensions of round metal stairs for home, we should put the criterion on the line of movement, not on the narrowest part.
Application guide:
- In the line of movement, the bottom of the stairs should be about 24 to 30 cm so that the steps can be taken naturally.
- In the narrow part near the central column, it should not be so low that the foot gets stuck or feels like slipping.
That is why the diameter of the stairs and the distance of the central column have a direct effect on the comfort of the stairs. The more suitable the diameter and the more accurate the design, the more standard the stair floor will be in the actual walking path.
Additional note:
If your family has children or the elderly, it is better to adjust the movement line so that the floor of the stairs is bigger and safer in that direction, and the surface of the stairs is anti-slip.
Standard slope and feeling of comfort in round metal stairs
The slope of the stairs is the result of combining the height of the stairs and the bottom of the stairs. In the standard dimensions of the round metal staircase for the home, the goal is not to make the slope too steep, because the round staircase itself has a turning path, and if it is steep, the risk of slipping and fear of heights increases.
In practice:
- Riser about 16 to 18 cm
- Step floor on the movement line about 24 to 30 cm
This combination usually gives a slope that is suitable for everyday use. If your space is very limited and you have to make the stairs smaller, you should increase the safety by increasing the accuracy of the railing, footrest and anti-slip.
How is the number of steps and the degree of rotation determined?
One of the key questions when ordering is how many steps and how many turns the round staircase will take. This issue is one of the standard dimensions of round metal stairs for the home, because it determines the rhythm of walking on the stairs.
General process:
- The height of floor to floor is measured.
- A suitable riser is selected.
- The number of stairs is obtained.
- Then, based on the diameter and conditions of the opening, the rotation angle of each stair is adjusted so that the entry and exit of the stair is in the right place.
Important note:
In real houses, the entrance to the stairs and the exit should be in harmony with the passage, doors and furniture. A numerical design is not enough and a map and placement should also be seen.
The standard dimensions of the tread and the entrance and exit of the stairs
Many people think that a round staircase is always without a footrest, but in some projects, the presence of a small footrest or an entry and exit platform makes transportation easier and safer. In the standard dimensions of round metal stairs for the home, there should be enough space in front of the first and last step so that the user can start or finish the path without getting stuck on the wall or fence.
Simple rule:
Standard dimensions of railings and bumps in round metal stairs
The railing in the round staircase is not just a decorative component. The fence is the main part of safety and should be taken seriously in the standard dimensions of round metal stairs for the home.
Important items:
- The height of the bump should be such that when going up and down, the hand can easily rest on it and prevent falling.
- The distance between the components of the fence should be such that there is no danger for children to get stuck or pass.
- The connections of the fence to the body of the stairs and the floor should be made firmly and without looseness.
In the round staircase, because it is a circular path, the quality of the railing and its continuity are of double importance. The bump should give a sense of integrity along the way and not confuse the user at the points of change of direction.
If safety is your priority and you want the fence to be both beautiful and standard, ask Damavand Firoozkoh Round Stairs to introduce some fence models that match the style of your home to get the best balance between appearance and security.
The standard dimensions of the central column and its effect on the comfort of the stairs
In many round metal stairs, the central column plays the main structural role. The diameter and material of this column affects both the safety and the floor of the stairs in the inner part.
If the center column is selected too large:
- The narrow part of the bottom of the stairs will become smaller and the internal path will become more uncertain.
If the central column is too small or weak:
- The possibility of vibration, noise, or reduced stability increases.
So, in the standard dimensions of round metal stairs for home, a balance should be maintained: the column should be strong enough, but the design of the stairs should be such that the footer remains in the right path. This is exactly where constructive experience becomes important.
Stair floor material and anti-slip standards
When we talk about the standard dimensions of round metal stairs for the home, it is not only the length and width that matters. The level of the stairs is also a part of the functional standard. A round metal staircase can have a metal, wooden or mixed floor. But in any case, you should pay attention to these points:
- The surface of the stairs should be non-slip, especially if wet shoes or socks are placed on it.
- The edge of the stairs should be designed so that it does not catch the foot and is not sharp and dangerous.
- The sound of footsteps on metal stairs should be managed; With proper design and accurate implementation, vibration and sound can be reduced.
Common mistakes in choosing the dimensions of round metal stairs for home
In order to correctly choose the standard dimensions of round metal stairs for the home, it is better to know some common mistakes:
Choosing the diameter based on the smallest possible space
A very small diameter may fit on the map, but it can cause dissatisfaction in everyday life. It is better to consider at least a comfortable space.
Ignoring the line of motion
If you only look at the widest part of the bottom of the stairs, you might think that the stairs are comfortable, but in actual use, people walk on the middle part. Measure the standard on the same track.
A weak or purely decorative fence
In the round staircase, the railing should be strong, continuous and comfortable. Improper fence multiplies the risk.
The difference in the height of the stairs
Even a small difference causes slippage or imbalance. All steps must be executed uniformly and precisely.
