Frequently Asked Questions

Are prices indicated for the two stringers?
Are steps/treads included?
No. 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 step supports. The following standard materials or equivalent are recommended :

2x10s or 1" hardwood treads: up to 36 inches wide
2x12s or 1¼" hardwood treads: up to 48 inches wide
What about railings and risers?
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.

There are two simple methods for attaching railings (not included) to your stairs:

1. with railing posts fastened from inside the perforated steel stringers and railing boards fastened to posts above stringers (easiest method)
2. with railing posts and system attached to the top of the treads
Are Fast-Stairs stringers code compliant?
Yes. Our A model (7 7/16" riser height) and B model (7¾" riser height) stringers are residential stair building code compliant everywhere in the US and Canada. Our C model (8¼" riser height) stringers are OSHA compliant. Our P models (6⅞" riser height) are commercial/public space code compliant.
How do I determine which Fast-Stairs model I need
for my stair project?
Fast-Stairs provide a unique, quick and easy way to build long lasting, free-standing 2½ to 13 ft high stairs. No stair stringer calculator required. No more figuring out the rise and run of steps. Simply measure your floor to floor vertical height and then choose the Fast-Stairs adjustable model that fits the desired height of your stairs. Make sure you have the necessary bottom floor horizontal run and that your top floor opening is large enough (usually 75% of the horizontal run measurement) for an 80" head clearance.
Helpful Tips
In coastal areas or anywhere rust is a threat, we strongly recommend that you give the assembled stringers an extra coat of Rust-O-Leum, Tremclad brush or spray rust-proofing paint products. It will give you the opportunity to change the color of the stringers and add years of worry-free, no-maintenance ownership.

You can add lighting to your finished stairs by running thin LED light strips inside the C-channeled stringers.

Where needed, the use of intermediate outside support posts and/or fastening full-sized risers between treads will add rigidity to your finished stairs.
