ORI Stairs Key Benefits

Fast, modular stair access with less site work.

The ORI stair system is designed around prepared components, exterior-ready materials and simpler installation, then supported by OBS with quoting, delivery and install coordination.

01

Quick & Easy Installation

Prepared stair components reduce on-site cutting, fabrication and repeated coordination.

02

Weather-Resistant

Steel framing and exterior-ready timber treads suit outdoor access routes when site conditions are reviewed.

03

Modular

Transportable modules help with narrow sites, repeat townhouse work and staged installation.

04

Save Time and Labour

Less carpentry-heavy stair work means fewer trade overlaps and a cleaner path to handover.

05

Reusable

The system logic supports planned components that can be reviewed, moved or adapted on suitable projects.

06

Maintenance-Free

Designed to reduce maintenance pressure compared with site-built timber stairs exposed to weather.

Stair sizes

Standard ORI stair sizes for early project planning.

ORI Stairs use a 285mm tread depth and 175mm rise as the standard step dimensions shown on the original ORI stair guide. Final suitability should be checked against the project height, landing, fixing and access conditions.

  • Step range shown from 2 to 17 steps.
  • Height above ground reference included for early set-out.
  • Custom sizes can be reviewed for suitable projects.

Traditional timber route

  1. Measure and cut timber on site
  2. Build stringers, treads and handrail
  3. Weather delays and repeated adjustments
  4. Finish, repair and coordinate access late

ORI system route

Confirm the stair height and access, deliver the prepared ORI system, then install with coordinated OBS support.

FAQ

ORI Stair questions

What information do you need for a quote?

Send the floor height, ground level, stair location, access photos and any drawings. We check width, rise, going, landings and fixing points.

Can ORI replace a timber stair build?

On suitable projects, yes. The aim is to reduce carpentry-heavy stair construction and move the site to a prepared install package.

Can OBS deliver and install the stairs?

Yes. OBS can support suitable local projects with product supply, delivery coordination and installation.

Is the stair suitable for New Zealand exterior sites?

We review exposure, drainage, fixing conditions and project requirements before recommending the ORI stair system.

Do I still need design or consent advice?

Where required, yes. OBS helps with the stair system and installation planning, but project design, consent and code responsibilities should be confirmed by the project team.

Send us your stair height, drawings or site photos.

OBS can check whether ORI Stairs are a practical fit and plan supply, delivery and installation.
