Spiral Stairs, Kamloops, BC
Custom steel spiral staircases for Kamloops, space-saving interior and exterior spirals, including rooftop-deck access for valley-view homes, fabricated at our Burnaby shop.
Spiral Stairs, Kamloops
Custom steel and aluminum spiral staircases for interior and exterior applications, engineered to BC Building Code for residential and commercial use.
Spiral staircases solve a footprint problem, and in Kamloops that comes up most on bench-top lots where a loft, a rooftop deck overlooking the Thompson valley, or a basement suite needs a stair that does not eat the floor plan. We fabricate spiral stairs in steel at our Burnaby shop, centre column, welded tread brackets, and a curved railing, and install in Kamloops as a planned trip. Exterior spirals up to a rooftop deck are common here given the valley views, and those get the full dry-climate exterior spec: UV-stable finish, galvanizing where it touches grade, and thermal-movement allowance. Interior spirals to a loft or suite are powder-coated to match the interior. Every spiral carries a sealed engineered drawing.
Kamloops is our anchor city in the BC Interior. We fabricate at our Burnaby shop and run completed assemblies up the Coquihalla (Highway 5) to Kamloops sites, a model that suits the larger institutional, commercial, and custom-residential scopes the city generates. Our reference project here is the stair fabrication and installation we delivered for Interior Health at Royal Inland Hospital. Kamloops sits at the confluence of the North and South Thompson rivers in a semi-arid valley: hot dry summers above 35°C, intense UV, low annual precipitation, and wide day-to-night temperature swings. Those conditions change the metalwork brief, UV-stable powder coat over salt-driven galvanizing logic, and thermal-movement detailing on long steel runs that you don't worry about on the coast.
Configurations we fabricate
Kamloops context
Kamloops's climate, building stock, and permit process shape every spiral stairs project we deliver here.
Climate
Design snow load for Kamloops is roughly 2.4 kPa ground. Coastal exposure is none. Interior seismic zone, lower demand than the coast, but connections still detailed per CSA W47.1. These are the numbers the engineer pulls when sizing steel for a spiral stairs here.
Permits
City of Kamloops requires building permits for new staircases, structural modifications, and load-bearing guardrail work. Confirm scope with the Kamloops building department before fabrication.
Local neighbourhoods
We work throughout Kamloops, including Sahali, Aberdeen, Lower Sahali, Upper Sahali, Downtown / City Centre, North Kamloops, Brocklehurst, Westsyde. Most sites are a 3.5 hours via the Coquihalla (Highway 5) drive from our Burnaby shop.

Process
1. Site visit and opening check. Confirm the opening diameter, headroom clearance, and floor-to-floor height for code compliance.
2. Engineering. Sealed drawing sizing the central column, tread brackets, and guard system to code.
3. Shop drawings. Tread layout, column section, guard detail, and finish schedule.
4. Fabrication. Central column, tread brackets, and guard fabricated at our Burnaby shop.
5. Finishing. Powder coat for interior; hot-dip galv + powder coat for exterior applications.
6. Installation. 1 to 2 days for a residential spiral; longer for complex commercial applications.

FAQs
Answers to the questions we hear most often from Kamloops homeowners, architects, and GCs on spiral stairs projects.
Spiral stair cost in Kamloops depends on diameter, tread count, interior versus exterior, railing detail, and finish. Exterior spirals to a rooftop deck cost more than a simple interior loft spiral because of the weatherproof spec. The Burnaby delivery is one planned install. <a href="/request-a-quote/">Request a quote</a> and we'll follow up with project-specific pricing.
Yes, and it is a common request given the valley views. Exterior spirals get hot-dip galvanizing where the structure meets grade, a UV-stable topcoat for the strong Interior sun, and thermal-movement detailing so the column and treads handle the wide day-to-night temperature swing. The City of Kamloops permit and a sealed engineered drawing apply.
Spiral diameter is driven by the BC Building Code requirements for tread depth and headroom, and by whether the stair is a primary or secondary route. We size the diameter to the opening and the use, and confirm headroom at the upper landing before fabrication, there is no room to adjust a welded steel spiral on site.
Yes. We fabricate the column, treads, and railing complete in Burnaby, then deliver and install in one mobilization up the Coquihalla, the same model behind our Interior Health stair work at Royal Inland Hospital.
A duplex system, hot-dip galvanizing plus a UV-stable powder topcoat. The dry climate is easier on steel than the coast, but a rooftop spiral takes full sun, so colour-stable topcoat matters more here than corrosion protection alone.
