Introduction to Stair Landing
Flight of stairs landing is a significant part of a structure giving admittance to various floors and roof of the structure. It’s anything but a flight of steps and at least one intermediate landing pieces between the floor levels. Stairs can be characterized as arrangement of steps appropriately orchestrated the reason for associating various floors of a structure.
It might likewise be characterized as a game plan of treads, risers, stringers, newel post, hand rails, and baluster, so planned and built as to give a simple and fast admittance to the various floors.
A bunch of steps shaped to make it conceivable to pass to another level by walking by putting one foot after the other via landing to ascend or down the step. Stairs landing can be made of concrete, stone, wood, steel or mix of any of these.
What Is Stair Landing?
A level stage or segment at the top or lower part of a flight of stairs. For security reasons landings are additionally used to separate in any case too long flight of stairs or they are utilized when a shift in course is required.
An intermediate landing is a little stage that is worked as a feature of the step between fundamental floor levels and is normally used to permit stairs to alter bearings, or to permit the client a rest.
A half landing is the place where a 180° course adjustment is made, and a quarter landing is the place where a 90° course adjustment is made (on an intermediate landing). As intermediate landings burn-through floor space they can be costly to construct.
Be that as it may, altering the bearing of the stairs permits stairs to fit where they would not something else, or gives protection to the upper level as guests downstairs can’t just look into the stairs o the upper level because of the shift in course.
Stair Landing Dimensions
The width of each landing will not be not exactly the flight of stairs served. Each landing will have a base element of 36 inches (914 mm) estimated toward movement. The most extreme height of riser is between 150mm 200mm.
Types of Stairs
1. Straight Staircase
2. Straight Stairs with a Central Landing
3. L Shaped Staircase
4. U Shaped Staircase
5. Spiral Staircase
6. Staircase with a curve
7. Bifurcated Staircase
The Bifurcated Staircase is a staircase that is divided into two halves.
8. Ladder Staircase
9. Staircase Winder
10. Cantilever Staircase
The stair threads on the Cantilever Staircase look to be floating in mid-air with no support. The treads are secured to one end by producing divets in a metal frame, while the other end either secures a railing system or floats freely.
11. Circular Staircase
12. Space Saving Staircase
13. Staircase with Storage
14. Bent Metal Staircase
15. Straight Stairs with Top Landing
The straight stair has a landing at the top that extends to the floor in this variation.
16. Alternating Tread Stairs
Each foot generally uses only approximately half of each tread on standard stairs, stepping out and over the unused area.
17. Crossover Stairs
Crossover stairs are typically seen in industrial settings, and they’re great for getting to equipment and mezzanines, as well as giving a method to get around machines, pipes, mechanical ducts, and other obstructions.
18. Stair Towers
19. Scissor Stairs
In Which Cases, Stair Landing Are Needed?
When the steps cover a difference of over 2.50 m levels, an intermediate landing should be provided. The landing length should extend over the whole stair width at least 1.20 m. At the top and bottom of each escalator flight landings must be provided.
The distance from the top and bottom must be longer than the stairwell width (see diagram). There should be no door on the front of any step closer than 400mm. All landings should have a gradient other than the level in the ground floor.
At least the width of the escalator should be equal to the landing in the direction of travel and the staircase should not exceed 1219mm when the staircase is straight. If a door is opened at the landing, the landing should not be less than half the required width. In addition, it shouldn’t project more than 178mm on the landing when the door is fully opened.
Stair landing on the top and bottom of each outside and inside staircase flight should be provided. Stair landing is required if a door swings towards the stair at the top of the flight. A medium landing should be provided for stairways with a straight line that have an overall rise of more than 3.65 m.

Conclusion of Stair Landing
The top or bottom part of a stair flight level stage or segment. In addition, landings are used to separate too long stair flight in any case for safety reasons or are used when a shift is necessary. A small stage of an intermediate landing is a step between the floors and usually used to allow stairs to modify the room or allow the customer to relax.
One half landing is the place to adapt the course to 180 degrees, the place to adjust the course to 90 degrees is a fourth landing (on an intermediate landing). They can be expensive to build as intermediate landings through floor space
