A steel staircase is compromised of the following elements:

#1 Steps

Steps are comprised of two sections, the tread, and the riser. The tread is the horizontal part of the step that the foot is placed on. The riser is the vertical portions between each treat. Often in steel staircases, the riser of left out, giving the flight an “open stair” look. Nosing is the part of the tread that sticks out past the riser.

#2 Starting step (Bullnose)

The starting step is a first step that may have one or two open sides and are often larger than the rest of the steps.

#3 Stringer

Stringers are the structural element that supports the tread and risers. There are usually two – one on either side of the stairs.

#4 Winders

Winders are stairs that are narrower on one side than the other. They are used to alter the direction of the staircase (spiral staircases contain only winders).

#5 Trim

The trim is applied where the walls meet the floor or where the tread and riser meet (think to skirt for walls).

#6 Bannister (handrail)

The element of the stair for holding. Steel staircases can have one, two, or no bannister at all. In the case of larger staircases, there can be one (or multiple) handrail(s) in the middle of the flight.

#7 Volute

The end of a handrail that curves around the starting step in a spiral shape.

#8 Gooseneck

The gooseneck is a vertical handrail that vaults to reach a higher handrail or the railing of a balcony.

#9 Baluster

Balustrades are the vertical bars that connect the handrail and the tread.

#10 Newel

The newel is a large baluster that anchors the handrail. These are structural elements that often extend below the floor for greater structural integrity. In the case of staircases with an open landing, newels may extend past the landing right down to the floor.

A steel staircase will last longer, is more eco-friendly, is more cost-effective and will look better than any other building options that might come your way. If you are considering steel frames for your new staircase and would like a professional opinion, contact us.
