Step/treads, Railings and Risers for Steel Stair Stringers

Step/treads, railings and risers are not included with our stringers. Customers make or get those locally to their taste and budget. All pictures on our website were sent by customers having gone through this process. Fast-Stairs® specialises in providing what is the hardest part in building stairs (the frame) and what can’t be found elsewhere: modular adjustable steel stair stringers.

We recommend the following for step/treads, railings and risers which are not included with Fast-Stairs® stringer products:


Measure and/or determine the width of your stairs and cut same size step/treads you choose (from 2x’s to the best hardwood and other fine stair finish products you’ll find locally) to screw onto the perforated steel step supports. The following standard materials or equivalent are recommended :

2x10s or 1″ hardwood treads: up to 36 inches wide
2x12s or 1ΒΌ” hardwood treads: up to 48 inches wide

Make sure that all step/tread materials you add to your Fast-Stairs® stringers comply with the materials’ load capacity.


There are two simple methods for attaching railings to your stairs:



If required, simply screw risers to the back edge of the fastened step/treads.
