Stairways may be straight, round, or may consist of two or more straight pieces connected at angles. We will introduce the stairs components to help the customer order the right stair composition.

The Stairs composed of:

Sunny Medium Stairs l Egypt Marble

The tread is the part of the stairway that is stepped on. It is measured from the outer edge of the step to the vertical “riser” between steps.

Riser is the vertical portion between each tread on the stair. This may be missing for an “open” stair effect.

Nosing – An edge part of the tread that protrudes over the riser beneath.

Starting step or Bull nose – Where stairs are open on one or both sides, the first step above the lower floor may be wider than the other steps and rounded and the where the balustrade or the handrail typically form a semi-circle around the circumference of the rounded portion and the handrail has a horizontal spiral. The starting steps allow the balusters to form a wider, more stable base for the end of the handrail.

Winders are steps that are narrower on one side than the other. They are used to change the direction of the stairs without landings. A series of winders form a circular or spiral stairway. When three steps are used to turn a 90° corner, the middle step is called a kite winder.

Stringer board is the structural component that supports the treads and risers. There are typically two stringers, one on either side of the stairs; though the treads may be supported in many other ways.

Trim is normally applied where walls meet floors and often underneath treads to hide the reveal where the tread and riser meet.
Balustrade is the complete system of railings and balusters that prevents people from falling over the edge.

Anti Slip Stairs Tiles and floors

EMG  is offering anti-slip stairs & flooring, it is the finishing technique that grooves a pattern into the existing surface creating instant traction improvement to slippery stairs & floors. 

The shallow groove acts like a tread and removes the film of water preventing hydroplaning on the sole of your shoe. Smooth surfaces underfoot seem somewhat precarious, but mixed with water can become potentially lethal.
Slip-resistant stairs and floors can prevent serious injuries.  Anti-slip finishing is most suitable for stairs, outdoor floors and in swimming pool areas.

Stairs Tiles measurements

The rise height of each step is measured from the top of one tread to the next. It is not the physical height of the riser; the latter excludes the thickness of the tread.

The tread depth or length is measured from the edge of the nosing to the vertical riser.

The total run of the stairs is the horizontal distance from the first riser to the last riser. It is often not simply the sum of the individual tread lengths due to the nosing overlapping between treads.

The total rise of the stairs is the height between floors (or landings) that the flight of stairs is spanning.

The slope of the stairs is the total rise divided by the total run (not the individual riser and treads due to the nosing). It is sometimes called the rake or pitch of the stairs. The pitch line is the imaginary line along the tip of the nosing of the treads.

Headroom is the height above the nosing of a tread to the ceiling above it.

Walks line – For curved stairs, the inner radius of the curve may result in very narrow treads. The “walk line” is the imaginary line some distance away from the inner edge on which people are expected to walk. Building code will specify the distance. Building codes will then specify the minimum tread size at the walk line.

To avoid confusion, the number of steps in a set of stairs is always the number of risers, not the number of treads

Stairs Tiles guide measurements

The easiest way to calculate the rise and run is to use a stair stringer calculator. Standard dimensions can be determined by following

Riser: maximum riser height, typically 8.25 inches (210 mm). A minimum riser height is often 5 inches (125 mm).

Tread: minimum tread length, typically 9 inches (229 mm) including the nosing for private residences

Nosing: maximum nosing protrusion, typically 1.25 inches (32 mm) to prevent people from tripping on the nosing.

Handrail: height of the handrail is typically between 34 and 38 inches (864 and 965 mm), measured to the nose of the tread. The minimum height of the handrail for landings may be different and is typically 36 inches (914 mm).

Handrail diameter: the size has to be comfortable for grasping and is typically between 1.25 and 2.675 inches (37 and 68 mm).

Balusters of the handrail: in between space maximum typically 4 inches (102 mm).

Openings(if they exist) between the bottom rail and treads are typically no bigger than 6 inches (152 mm).

Floor and landings in between maximum vertical height between should allow people to rest and limits the height of a fall.
