A Systems Solution To Custom Stairs


Designed Stairs Inc. (DSI) has spent the past several years analyzing the stair needs within the building systems industry, resulting in two product lines specifically designed for the modular/systems built/panelized home building concepts.

The first product line is the “Production Seriesâ€? Pre-Assembled Rail and Staircase Units. These components allow manufacturers to greatly increase the quality and structural integrity of their stair construction while actually lowering their labor and overall costs. These rail units boast true American craftsmanship and materials and will completely blow away any “out of the boxâ€? rail systems available to the modular industry. Home buyers will notice the difference when they look at your competitors “expand-o-rail.”

The second product line is our “Builder’s Choiceâ€? Premium Oak Staircase. These beautifully milled staircases give modular manufacturers the ability to offer their builder network an optional staircase that exceeds the custom look that even their “stick builtâ€? competition can offer.  These staircases are custom built to the exact specifications that we receive from your engineering department, all of the components are pre-cut and pre-drilled. Your builders can install the average modular design in under four hours and they are available pre-finished, and your production line can completely eliminate the stair process within your plant!
