Beyond the catalogue
If you can draw it, we can usually build it
The Swhift difference
We publish what most fabricators make you ask for
Our sizes are public
Every stock diameter, length, capacity and weight is on a downloadable chart — pressure and non-pressure both. You can price and plan a job before anyone picks up the phone.
Mechanically assisted welding
Tank circumferences are closed with a continuous mechanically assisted weld rather than a series of hand restarts. Fittings are then welded in by hand by our fabricators.
A written warranty, not a promise
Five years on pressure tanks, ten on non-pressure, with the conditions stated plainly — including the chlorine limits by grade and the relief valve requirement.
One production manager per project
Each project is managed by a single production manager. You are not handed between departments, and the person you speak to knows where your tank is.

How a tank gets built
From a sketch on the phone to a tank on a truck
- 01
Tell us the job
Capacity, space, what goes in the tank, and whether it holds pressure. If you do not know a field yet, say so — consultations are free and we will work it out with you.
- 02
We quote it
Stock size off the chart where one fits, or built to your dimensions where it does not. Grade, finish, pressure test and fittings all get confirmed in writing.
- 03
We build it
Hand-rolled and hand-welded, with mechanically assisted welds on the tank circumference. Nothing leaves the shop without being checked.
- 04
We ship it
Crated and loaded for the trip. We ship across the country and worldwide, and a single production manager keeps you posted the whole way.

Plan before you buy
Tools and guides that answer the question first
Start a project
Tell us about your project
Send dimensions, a layout sheet, a photo of the space, or just a description. We will tell you what we would build and what it costs — and if a stock size gets you there cheaper, we will point you at it.
Consultations are free. Every project is managed by a single production manager, so you talk to the person who knows your job.
Prefer to just call?
You will reach the shop, not a call centre. Consultations are free, and if we are not the right fabricator for your job we will say so.
