Stairways, stairs flights of stairs, spirals stairs and staircases, there are many different names for them, but they are all designed to do the same thing, to get you from one level to the next as safely as possible. They bridge a large vertical distance by dividing that large distance into smaller vertical distances.
Â
If it was not for staircases we would be using ropes and ladders to bridge vertical distance which is really not safe or particularly practical for the very young, elderly, disabled or sick. Stairs come in many different shapes and sizes and can be round or spiral to save space or flat as is more common in a modern environment.
Â
Stairs are generally constructed of two major components, the riser and the tread. The tread is the part of the stair that is actually stepped upon and is horizontal and the riser is the vertical part connecting the treads together. Occasionally the riser will not be present, this is called an open staircase or open stairs.
Â
Stair cases also are often accompanied by a banister or balustrade also known as hand railings. These are for the purpose of being held on to while ascending or descending the stairs and provide balance and stability. These can come in the form of steel balustrades, glass balustrades or wooden balustrades.
Â
Over the centuries stairs have evolved considerably and are now constructed from a multitude of materials including brass, steel, glass, marble, granite and bronze. Stairs are also often constructed of wood and covered in carpet to reduce noise and provide insulation.
Â
Building a staircase is a highly skilled task and requires highly skilled craftsmen and detailers. Highly skilled teams are required to make the structural calculations needed to ensure the safety and stability of a stair case. Newly designed stairs will first be assembled in a workshop by a skilled team before being installed onsite.
