Pacific Stair has designed a stacking stair system that solves many of the common problems found in the construction industry; access, elevation issues and tolerance build up. Stack-A-Shaft™ systems are flown into place and are ready for use in typically under one hour providing immediate access for your crews.  Our Stack-A-Shaft™ is designed for multiple building configuration and construction techniques.

SAS™-LG Light Gauge Steel Structures

• Designed to connect directly to light gauge members
• Self Supporting, no need for additional steel for stair     openings or support      

SAS™-WF Wood Framed Structures

• SAS™ come with connections for wood joists or 

           beams

SAS™-PT Concrete Post Tension Slab Structures

• Installed BEFORE slab is poured, helps to confirm elevations

SAS™-HS Heavy Structural Steel Structures.

• Multiple attachments available, bolting or welding as required
• Ability to set stairs without the need to have all decking in place

With Stack-A-Shaft™ trades are using the stairs during the construction phase

Access to the highest working deck

Eliminate the cost and the need for temporary stairs, wood ladders or manlifts to get workers to the highest working platforms

Keeps your project OSHA compliant from

day one

Finish floor elevations are pre-determined by the Stack-A-Shaft™ system and are easier to control

Floors are framed to the Stack-A-Shaft™ eliminating the guess work

Discrepancies are better controlled by having a fixed reference point to work from

Needed changes in elevation are more precise with Stack-A-Shaft™ system

Combining Stack-A-Shaft™ technology with our new Quiet Tread™ or our new post consumer Versa-Tread™ gives customers and contractors a product that not only allows for immediate access, but helps to control building costs as well

No need for comeback work to fill treads

Discontinue the use and disposal of wood blocking on poured treads

No more concrete clean up after pouring and prior to painting

Versa-Tread™Allows for two working surfaces, a construction surface and a finished surface

With Versa-Tread™ simply turn the tread over to expose the finish surface with the treatment of your choice
