Stair and Platform Access System: Zero Welds, Built Faster.
3 minute read
Published 23 July 2026
The SlotPro Stair and Platform System is a modular t-slot aluminium alternative to welded steel access structures. Engineers, machine builders, OEMs, and facility teams across New Zealand use it for stairs, platforms, and walkways. This avoids the cost and downtime that welding brings.
The Stair and Platform System, or SPS, sits alongside SlotPro’s wider range of t-slot aluminium components.
Why Welded Access Systems Are Falling Behind
Welded steel stairs and platforms have been the default access systems in NZ facilities for decades. But the process comes with fixed costs that don’t go away.
Every welded structure needs a qualified welder, a fabrication shop, and lead time to cut, weld, and finish steel before it ever reaches site. If a layout changes after installation, the fix usually means grinding out welds, recutting steel, or starting again.
SPS removes that dependency. It is assembled from t-slot aluminium profiles using a single 5mm hex key. No welding and no specialist fabrication required.
What the Stair and Platform System Offers
SPS is designed around the same principles as the rest of the SlotPro range: modular, flexible, and simple to work with.
Key features include:
- No welding: Structures are bolted together with t-slot connectors, so there’s no heat distortion, no fabrication shop booking, and no welding certification required on site.
- Reconfigurable design: If a production line moves or a platform needs to be extended, SPS can be adjusted or relocated. A welded structure is fixed and can’t be modified.
- Faster installation: As components arrive precision machined to spec, assembly is a matter of bolting sections together rather than cutting, welding, and finishing steel on site.
- Consistent quality: Every profile is machined to the same tolerance, every time, which removes the variability that comes with manual welding.
This matters most for stair and platform access system projects where layouts change often, such as machine builds, packaging lines, and maintenance walkways.
The Cost Case
The price difference between welded and modular access systems isn’t just about materials. It’s about labour, time, and rework.
A welded stair or platform ties up a qualified welder and a fabrication bay for the full build. Any design change during the project means rework which is slow and expensive.
SPS is priced and built differently. Profiles are stocked locally in New Zealand and precision machined to spec, so lead times are shorter and labour is limited to assembly rather than fabrication. For facility and maintenance managers working to a budget, that difference shows up directly on the invoice and the project timeline.
Built for Safety Compliance
Access platforms and stairs in New Zealand workplaces need to meet clear safety standards, particularly around fall prevention and safe egress. Health and safety managers evaluating any access system, welded or modular, should reference current guidance from WorkSafe New Zealand when planning platform height, guarding, and stair design.
SlotPro’s CAD support helps teams design and build SPS to the specific height, guarding, and access requirements of their site, so compliance is built into the layout from the start.
Who SPS Is For?
The Stair and Platform System is for:
- Machine builders and OEMs needing standard access points across multiple builds
- Fabricators looking to cut labour hours on repeat projects
- Facility and maintenance managers who need platforms that can move as operations change
- Engineers and designers who want CAD-ready components instead of custom steel drawings
Getting Started with the SPS
SlotPro offers CAD support for teams designing with SPS, so layouts can be modelled and adjusted before any material is ordered. Full specifications and part options are available on the Stair and Platform System product page.
Teams already using SlotPro’s t-slot range for guarding or framing can view compatible components through the 1Guard modular guarding range or explore the full catalogue via SlotPro’s shop.
