Classification of Staircases Used Commonly

When deciding to build a stair, you need to know what type of stair you want to use. For this, you need to be well versed in stair terminology. Today, we will talk about the types of stairs in use throughout common building practices.

Types of Stairs: The Types of Stairs that are common in residential and commercial buildings are -

1. Straight Stairs
2. L Shaped Stairs
3. U Shaped Stairs
4. Winder Stairs
5. Spiral Stairs
6. Curved Stairs
7. Ladders

Now let us see about them in detail.

Straight stairs: Straight stairs will be stairs without any adjustments in heading. They are certainly one of the most widely recognized sorts of stairs found in both residential and commercial properties. Below are examples of straight floating stairs made with an assortment of stringer styles, railing types, and wood species.

Straight stairs with a central landing: On longer flights of stairs, a landing is embedded to separate the flight. Building codes require this for floor heights over 12 feet. Especially in commercial buildings, straight stairs frequently have platforms halfway up the run of the stairs.

Pros of Straight Stairs:

a. Straight stairs will in general be the most straightforward to go up and down, or, rise/dive, as we state in the industry.
b. They are typically the most effortless to build, in any case, this relies a lot upon the level of detail in the design.
c. Straight stairs only should be associated at the top and the base (no middle supporting structure is required).

d. They function admirably with minimalist designed homes due to their inborn simplicity.
e. By selecting more slender tracks, open risers, and slim metal stringers, straight stairs can be made more straightforward than different sorts of stairs, allowing less obstruction to the view past.
f. No landing is required if the number of risers is held under 16 or the overall vertical tallness is less than 12 feet.
g. It's relatively simple to build railings and handrails for straight stairs.
h. Measuring for railings for straight stairs is simpler than for other stair designs.

Cons of Straight Stairs:

a. Straight stairs use up a considerable measure of linear space, which must be planned for in your design.
b. A portion of the other stair types make a protection hindrance between the floors of your home. Straight stairs don't offer this protection.
c. A stair 12-feet high requires a landing to separate the range. The expansion of a landing will use up a lot more space and in this way these sorts of stairs are seldom used in residential construction. You will see these all the more frequently in large commercial buildings.

L shaped stairs: The L shaped stair is a variety of the straight stair with a twist in some segment of the stair. This curve is usually accomplished by including a landing at the progress point. The twist is frequently 90 degrees, in any case, it doesn't need to be. On the off chance that the landing is closer to the top or base of the stairs it is now and then alluded to as a long L stair or a quarter turn stair.

Pros of L Shaped Stairs:

a. L shaped stairs can be all the more visually fascinating.
b. They give a visual obstruction between floors in this way, they can include some protection.
c. L shaped stairs can help to some degree with sound transmission between floors if the stairs are contained inside walls.
d. Some believe they are more secure than straight stairs as the central landing reduces the number of tracks one could fall in a given flight.
e. The landing can give a place to stop and rest while climbing.
f. They can be located in a side of a room if this works better for your design.

Cons of L Shaped Stairs:

a. L shaped stairs are more difficult to build than straight stairs.
b. A support is typically required for the landing in a L type stair. Frequently, this is built into the surrounding walls so it goes unnoticed. In present day dwellings, in any case, it is usually desirable to open up the space by leaving the stair structure visible. In these cases, the supporting structure can be visually limited by exploiting the quality of steel to make slim supporting individuals. Through careful engineering, it is possible to eliminate the landing support altogether.
c. Handrails for these sorts of stairs require more skill and planning to construct than handrails for straight stairs.
d. In climates where storm cellars or basements are used, stairs are typically stacked over one another for proficient use of room. Since basements are regularly used for capacity, large things can be difficult to move all through the storm cellar.

U Shaped Stair: U shaped stairs are essentially two parallel flights of straight stairs joined by a landing that makes a 180-degree turn in the walk line.

Pros of U-Shaped Stairs:

a. U shaped stairs can be simpler to fit into an architectural plan.
b. They offer some architectural intrigue.
c. The landing(s) can offer a resting point partially up the stairs.

Cons of U-Shaped Stairs

a. These sorts of stairs are more difficult to build than simpler stair types.

Winder Stair: Winder stairs are a variety of a L shaped stair but rather than a flat landing, they have pie-shaped or triangular strides at the corner progress.

Pros of Winder Stairs: The primary bit of leeway of winder stairs is that they require less space than numerous different kinds of stairs. They are exceptionally basic in older homes and frequently used as an optional staircase. For example, they are regular in homes where the stupendous staircase is in the passage. In these cases, the winder stair is frequently used as an entrance to the kitchen.

Also, they do have more visual enthusiasm than other stair types. Winder stairs appear to make a progressively seamless change, visually, as they wander around corners. Thus, they have picked up popularity in present day homes. Their smallness has also made them alluring in sustainable home designs.

Cons of Winder Stairs:

a. Winder stairs are a little harder to explore than L stairs.
b. It tends to be increasingly difficult to add a handrail to these than a portion of different kinds of stairs.
c. Like with L shaped stairs, an inside support is typically required.

Spiral Stair: Spiral stairs follow a helical bend. They usually have a minimized design and the tracks transmit around a central pole.

Pros of Spiral Stairs: One of the key favorable circumstances of spiral stairs is their conservativeness. They are extremely popular on sea shore front decks where space is at a premium. They are also used extensively on city lofts for a similar explanation.

Spiral stairs can be appealing and there are numerous minor departures from railings styles which can majorly affect the overall appearance of the stair.

Since the middle pole and landing typically offer the structural help for the stairs, they needn't bother with much in the method for additional support structures, making installation simpler than with numerous different kinds of stairs.

Cons of Spiral Stairs: Spiral stairs are more difficult to explore than different sorts of stairs. It is hence that codes don't allow them to be used as the essential access to a full second floor of a home. Walkability improves as the outside width gets larger, so in the event that you have space, you might need to consider going somewhat larger. We suggest going 5 feet in breadth in the event that you can.

It is difficult to convey large things up spiral stairs. Only one individual can go up or down the stairs simultaneously.

Curved Stair: Like spiral stairs, curved stairs follow a helical circular segment. In any case, they will in general have a much larger radius and typically don't make a full circle. Curved stairs add elegance to any home or business. Consequently, they are almost always located at the section where they establish the best first connection.

Pros of Curved Stairs:

a. Curved staircases are frequently elegant and traditional but this kind of design can equally be adjusted to contemporary architecture.
b. They are relatively simple to walk up if the radius is large.

Cons of Curved Stairs: Curved stairs are by a long shot the most difficult to build of the various kinds of stairs. Truth be told, building curved stairs speaks to a pinnacle of accomplishment for any stair builder or fabricator. Therefore, they are the costliest to build.
