All our staircase stringers are manufactured to the highest quality standard and come in a range of widths and lengths.

Stringer Options For Your Staircase


What Is A Staircase Stringer?

A stair stringer (also called ‘string’ or ‘stringer board’) is the housing on either side of a flight of stairs, into which the treads and risers are fixed.

A staircase will have two stringers, one on either side of the steps. If one edge of the flight sits flush against an adjacent wall, the stringer that connects the treads and risers to the wall is referred to as a ‘wall stringer’.

Staircase stringers may be manufactured to ‘house in’ or hide the edge of the stairs from view, or cut and mitred to the shape of the stairs so as to expose the tread profile.

Cut Stringer Or Closed Stringer?

We can supply staircase stringers in a variety of different styles and materials. We sell pre-made stringers and can also manufacture custom stringers to your specifications. The two main forms of stringer are closed stringers and cut stringers. Closed stringers are designed to ‘house in’ or hide the edge of your stairs from view.

We sell pre-made standard stringer boards to 32mm thickness and 244mm height. These are available in 2.4, 3.6 and 4.2m lengths direct from our online shop. We strongly recommend using stair stringers of a minimum width of 32mm, as anything less can result in squeaky treads in your staircase.

Cut stringers on the other hand are cut to the shape of your stairs to display the side profile of each step. As with many of our stair parts, stringers are available treated for external installations. These cut stringers are supplied in lengths of 1m for 3 steps, or 1.6m for 5 steps, manufactured to 48mm thickness and 260mm height, and are produced to a 35° pitch (the angle of the stairs from top to bottom).

Pre-made interior cut stringers are not available to order although we do manufacture them as part of your staircase design. Thanks to the expertise of our experienced staff, we can even produce curved stringers where required, for use with curved staircases. We can also produce cut stringers with brackets. These stringers incorporate a decorative outside bracket, as well as showcasing the side profile of the stairs.

We don’t stock pre-made cut strings with brackets in our online shop. Get in touch with our design team to discuss the type of outside bracket you might want – we can produce brackets to our standard design, or to a design specified by you.

Routed Staircase Stringers

Routed stringers (sometimes called ‘box stringers’) are a type of staircase stringer which has been ‘routed out’ (‘hollowed out’) to incorporate notches into which treads, risers and wedges can be inserted.

It then acts as a supporting joist for each tread. Routed stringers can be used to increase the ease of staircase installation. Only closed stringers can be routed.

Stairs installed using routed strings are sometimes called ‘housed and wedged’ stairs. Sorry, custom and pre-made routed stringers are not available except as a complete staircase.
