~ Here at Unique Spiral Stairs, all units are designed to fit your individual space requirements ~

Standard Series Stairs

Unique's standard stair designs consist of four series of staircases available as interior or exterior models.

3QT Series - three quarter turn spiral stairs in seven standard designs ranging from 4' 6" to 7' diameter.

HT Series - half turn stairs in seven standard designs ranging from 6' 6" to 14' diameter

QT Series - quarter turn stairs in two standard designs - 14' and 16' 11" diameters.

ST Series - straight stairs available in standard 36" and 42" widths.

Unique's standard stairs have been engineered at a height of 114" and demonstrate impressive weight capacities for both tread and total stair capacity (see our specs page). This is particularly important when considering multiple person occupancy on the stair at one time. For longevity and stiffness all spiral stairs are constructed of multi-laminated all hardwood plies for the supporting stringer and handrail sets. Depending on the design - typical treads are made of solid 1 1/2' hardwood stock* with both ends recessed and bolted into their respective stringer mortises along with adhesive to assure a permanent fitment. All of Unique's hardware is fully concealed to retain the beauty of the wood stairs.

*Alternative species of hardwoods are available - see our Hardwood Options link on this page

Custom Series Stairs

Unique is proud to offer our superior custom curved stair designs. The challenge of designing what others are unable or unwilling to create is always welcomed by our craftsmen. Whether constructing to a specific diameter or designed to fit your specifications, Unique can provide the custom stair to meet your requirements. - "Throw us a curve"

Exterior Spiral Stair

Unique's exterior stairs are true works of beauty and are made to withstand the most demanding climate and weather conditions. You can select from fine lumber such as redwood, red cedar, white cedar, cypress, brazilian cherry, mahogany or teak in standard or custom designs.

Straight and Straight/Curved Combination Stairs

Unique can produce a straight run staircase complete with rails and drilled for balusters in a matter of days. Compare that to a site built stair. Substantial savings could result by just installing a pre-manufactured stair in place that is already assembled to the proper height.

If your project needs require a straight / curved combination stair, Unique has you covered with their crafty custom stair design capability.

Custom Landings and Balcony Rail Systems.

Unique also provides custom landing platforms in a standard square / rectangular configuration or in a custom curved fashion. Unique offers curved laminated fascia beams for circular openings, matching curved or straight balcony rail and nosings to dress the edge of the opening. We also provide millwork and hardwood accessories to add the finishing touch to your spiral stair application.
