Meet IStair.

ISTAIR is a patented residential stair system built off-site in a quality-controlled factory. Our proven system uses your plans or measurements to build the stair to fit your job. ISTAIR arrives fully assembled to the job site, ready to be installed at any stage of construction.




The Process.

The stair arrives.

Once you have placed your order with MPI Concepts, we will build and ship your stair to the job site. When the stair arrives, it is immediately ready for installation and can be completely installed less than 15 minutes. ISTAIR is Building Code compliant and ready for use upon proper installation.

Lift the stair in to place.

Our stairs can be easily installed by two men in less than 15 minutes. Once installed, you will be able to focus on the rest of your project, so you can get done faster, better and safer.

Fasten the stair in place. Done.

Once you have followed the 5-step installation process, you are set to go. The ISTAIR represents the most efficient and safe permanent framing method for staircases.
