Fabrication Capabilities
The lead shop, for contractors & installers
The Okanagan's duct & sheet-metal fab shop.
A dedicated duct and sheet-metal fabrication facility in Lake Country. We build to your drawings and field dimensions, close to the job.
Fabrication built around the job, not the catalogue.
Every run is different. We cut, form, and assemble duct and sheet metal to match your drawings, so your installers get parts that fit the first time.
- Rectangular duct
- Custom rectangular duct, offsets, and transitions built to your sizes and pressure class, sealed and ready to hang.
- Round & spiral duct
- Round and spiral pipe with matching fittings: elbows, reducers, and takeoffs cut to the run.
- Fittings & transitions
- The odd-shaped connections a job actually needs, fabricated instead of forced from stock parts.
- Plenums & equipment housings
- Return plenums, curbs, and custom housings built square and true to set on site.
- Flashing & architectural
- Custom flashing, cap and counter, and brake-formed sheet metal for the exterior and finish details.
- Specialty & one-offs
- Guards, pans, chases, and shop-drawn one-offs. Send a sketch and we build it.
The stock the trade specs.
Confirm gauges and any specialty stock with the shop when you send your drawings.
- Galvanized steel
- Aluminum
- Stainless steel
- Black iron
- Paint-grip / satin-coat
Set up to turn drawings into finished parts.
A working fabrication floor: coil-fed forming, cutting, braking, and assembly under one roof in Lake Country.
Forming & braking
Brakes and rolls for rectangular, round, and custom-formed sheet metal.
Cutting & layout
Accurate cutting and layout from your drawings, keyed to field dimensions.
Assembly & seaming
Sealed, seamed, and assembled to standard so parts arrive job-ready.
Metals & gauge reference
A quick reference for galvanized steel sheet. Thicknesses are the manufacturers' standard; the right gauge for a run depends on duct size and pressure class.
| Gauge | Thickness (in) | Thickness (mm) | Typical use |
|---|---|---|---|
| 26 ga | 0.022" | 0.55 | Small low-pressure duct, fittings |
| 24 ga | 0.028" | 0.70 | General residential and light commercial duct |
| 22 ga | 0.034" | 0.85 | Larger duct, medium-pressure runs |
| 20 ga | 0.040" | 1.01 | Large commercial duct, plenums |
| 18 ga | 0.052" | 1.31 | Heavy duct, housings, structural sheet |
| 16 ga | 0.064" | 1.61 | Heavy-gauge fabrication, curbs, guards |
Sizing follows the project spec and SMACNA. Confirm gauge and pressure class with the shop when you send drawings.
Questions from the trade
Straight answers on how the shop works. Anything else, just ask.
Do you fabricate for other contractors?
Yes. We supply general contractors, consultants, and installers with duct and sheet metal built to their drawings, as supply-only or supply-and-install.
What do you need to quote a job?
Drawings or a spec, the duct type and rough quantities, the metals and gauges required, your timeline, and the delivery site. A marked-up sketch is fine for one-offs.
What metals and gauges do you work with?
Galvanized steel, aluminum, stainless, black iron, and paint-grip. Gauges run through the common range for duct and sheet metal; confirm specific gauges with the shop when you send drawings.
What drawing formats do you accept?
PDF and common CAD formats (DWG, DXF), plus images or a ZIP of a drawing set. You can attach them straight to the quote form.
Do you deliver?
We serve Lake Country, Kelowna, West Kelowna, Vernon, and the wider Okanagan. Delivery is quoted per job based on the site and the package.
Is there a minimum order?
No fixed minimum. Send the job, whether it is a single transition or a full duct package, and we will quote it.
What is your turnaround?
Turnaround is quoted per job against the scope and the current shop schedule. We flag realistic timelines up front, not best-case ones.
Send the drawings. We quote the duct.
Rectangular, round, spiral, or a one-off. Get capacity and turnaround from the shop directly.
