If you’re in need of stair stringers, then you’ve come to the right place. At Metro Steel, we supply a wide range of pre-cut RHS and SHS steel for stair stringers or we can tailor a steel stringer solution to meet your exact specification and requirement.
What are stair stringers?
A stair stringer is the part of a staircase to which the treads and risers are fixed. As such, it plays a critical role in supporting the treads so that the stairs remain stable and safe for people to walk up and down on.
Typically, there are two stringers, one on either side of the staircase. When one side of the staircase lies flush against a wall, then the stringer which connects the treads and risers is known as a wall stringer.
Types of stair stringers
Stair stringers can be designed to hide or ‘house-in’ the edge of the stairs keeping them out of view or cut and mitred to match the shape of the stairs in order to expose the tread profile.
At Metro Steel, we can help you choose a stringer style that best suits your needs and matches the style of your home or commercial building.
Mono Stringers – for open staircases
One of the most popular styles of stringer is known as a mono or centre stringer. These form part of an open plan staircase with the stringer usually placed in the centre of the treads, although it can be offset. While mono stringers typically support treads made from timber, they can conceivably support treads made from a variety of materials including stone, glass, or steel.
When compared to traditionally styled stairs, mono-stringers stair designs are usually airier and more open because they’re not hidden by supports on either side of the treads. The metal stringers are usually less apparent because they’re placed beneath the treads themselves, usually in a central position. This gives the staircase a feeling of lightness and openness which is popular in modern buildings, especially.
It’s important that mono stringers are made from a strong material such as steel to give the stair structure the support it needs and make it stable and safe. Modern engineering methods and materials also mean that quite long spans can be achieved using mono stringers. Also, when compared to traditional stairs, mono stringers rely more on fabricated structural components, which we can supply at Metro Steel, such as laser-cut folded metal plates and square hollow steel sections.
Our approach to fabrication
Here at Metro Steel, we customise bespoke saw-type stringers, where space in which to fit the treads is cut away from the stringer profile. Alternatively, you may need the stringers to be located at the bottom of the treads, so they don’t interfere. In this case, some additional support will be required such as a steel plate and gusset method. Rectangular hollow section or SHS is usually the easiest and most efficient method of constructing mono stair stringers.
