Calculator
Z-Stack™ Height Calculator
Enter your required vertical height and we’ll calculate the number of Z-Stack modules for both Standard and Compact towers. Z-Stack exits at the top of the tower. Finish recommendations follow SafeSmart’s planning rules below.
Finish rules (tower below target): ≤ 9.5" nothing added • 9.6–24" bridge • 24.1–48" AdjustaStairs • ≥ 48" add module
Note: This tool is intended for quick planning. Final selection depends on site conditions and project requirements.
Standard Modules
Finish Recommendation
—
Standard is typically preferred when crews want a wider stair path and more room for tools/material movement.
Compact Modules
Finish Recommendation
—
Compact is commonly used when footprint is limited and a tighter tower layout is required for permanent installs.
Revolutionizing Vertical Access
Applications
Permanent Access
Z-Stack provides a safer, more practical alternative to fixed ladders and caged ladder systems in facility environments. Designed to support the movement of people, tools, and materials, Z-Stack offers stable stair access to rooftops and elevated areas without the need for ladder tie-offs or awkward climbs. The result is improved safety, easier material handling, and a permanent access solution that aligns with modern facility standards.
Temporary Access
Z-Stack is purpose-built for fast, repeatable access on active construction sites. Its modular design allows crews to build, adjust, and reposition stair towers as the job evolves—delivering safer access than ladders or scaffold stairs without slowing the schedule. Ideal for short-term elevations, multi-phase builds, and changing site conditions where speed, stability, and compliance matter.
Site-Specific Access
Z-Stack adapts to site-specific access challenges across industrial plants, tank farms, processing facilities, maintenance yards, and equipment-intensive worksites. Configure modular stair towers for tank access, elevated platforms, rooftop transitions, plant maintenance, and multi-level work zones—creating a stable, repeatable route wherever vertical access is needed.
Installing Z-Stack™
Z-Stack’s lightweight aluminum construction allows entire stair towers—or individual modules—to be craned directly into position with speed and precision. Whether shipped flat-packed, in modular sections, or fully assembled, Z-Stack is designed to deploy efficiently on site, minimizing handling time while maximizing flexibility across changing access requirements.
