Stainless Steel Fabrication Services: Design, Build, Install and Repair
Talk to our teamStainless Tank & Mix provides stainless steel fabrication services for Australian manufacturers, from the first sketch to equipment installed and running on your site. We’ve been designing, building, installing and repairing tanks, silos, mixers and process equipment in Sydney since 1974.
The same team carries a job all the way through. The engineers who model your vessel talk to the welders who build it, and the crew that installs it knows how it went together. When something needs repairing or changing years later, we already know the equipment.

Our Services
Design & Engineering
Every job starts as a 3D model. We work out what your equipment has to do, model it in SolidWorks and send you views to review and comment on until the design is agreed. FEA checks the structure, pressure and loads, and CFD models flow and mixing, before any steel is cut, and the same model becomes the fabrication drawings. We design new equipment, work from your drawings, or redesign equipment that has failed or outgrown its job.
29,700 L milk silo (three design rounds to fit under an awning), 3D-modelled IBCs for powdered product, specialised mixer design and 5,000 L replacement reactors.
Custom Fabrication & Pipework
One-off stainless steel equipment built to your process, in 304, 316, 316L or duplex. Alongside tanks and mixers, our Minto workshop fabricates process pipework, platforms, frames, chutes, skids and all the parts that don’t come out of a catalogue. Every weld is to AS/NZS 1554.6, and every job is built under our ISO 9001 quality system. We also source hard-to-find stainless steel items, from chain, wire rope and connectors to floats, hinges and special valves.
Custom fabrication of large tanks, a large stainless steel platform, a stainless steel jib crane and production line brackets.
Tank Installation & Relocation
Our installation team delivers and sets up silos, tanks, vessels, vats, mixers and the equipment around them. We run our own trucks and lifting gear, and because we built the equipment, we know how it should be lifted, positioned and connected. We also move existing equipment, whether that’s one tank across a production room or a whole line to a new site.
See tank installation and relocation ›Tank Repairs
A tank that’s been sucked in, cracked or worn out may still be worth saving. We assess the damage first and tell you whether a repair makes sense. We repair tanks we built and tanks from other makers, and we replace bases that have been patched too many times. We qualify our tradesmen for the jobs that call for it, and we work on site with as little disruption as we can manage.
Repairing a 24,000 L mix tank, a shear mixing head repaired, vacuum damage from poor design and ribbon blender maintenance.
Upgrades & Replacement Equipment
When a tank or mixer can’t be repaired, or your batch sizes have grown, we build the replacement to fit the space and the connections the old one left behind. We also upgrade what you have: new agitators, drives and fittings on existing vessels.
Replacement tank in 7 days, a replacement 500 L cooking kettle, a mixer upgrade and an upgrade to an existing anchor and shear mixer.
Our Services at Every Stage of a Project
Most customers use us for the whole job. Some bring us in for one stage. This is what we do at each one.
| Stage | What we do | What you receive |
|---|---|---|
| Design | Work out the duty, model the equipment in 3D and revise it with you | 3D views and a general arrangement drawing to approve |
| Engineering checks | FEA on structure, pressure and loads; AS 1210 design where the vessel is pressurised | Calculations and design documents |
| Fabrication | Build in our Minto workshop under ISO 9001 | Material certificates and weld records |
| Testing | Factory Acceptance Testing (FAT) before the equipment leaves the workshop | FAT records |
| Delivery and installation | Transport, lifting, positioning and connection on site | Equipment installed and ready to run |
| Repairs and upgrades | Assessment, on-site repairs, base replacement, upgrades and replacements | Equipment back in service |
Designed, Built and Installed by One Team
Everything we make is designed and fabricated at our workshop in Minto, NSW, from 2 litre vessels to tanks of 600,000 litres and more.
Size decides how a tank reaches you. Up to 3.5 m in diameter, it travels by road without an escort. Above that it needs an escort, and larger again a police escort, with bridges and overhead wires setting the real limit. When a vessel is too big to travel, we move the fabrication line to your site and build it there. That’s how we built a 600,000 litre tank at a power station.

Frequently Asked Questions
Do you install or repair equipment you didn't build?
Yes. We repair and service tanks from other makers as well as our own, and we can install or relocate equipment built elsewhere. We’ll look at it first, so we know how it was made before we lift or cut anything.
Can you relocate an existing tank?
Yes. We move tanks and process equipment within a site or to a new facility. We plan the lift, the transport and the reconnection, so the tank goes back into service quickly.
Can a damaged stainless steel tank be repaired?
Often, yes. Stainless steel is hard to bring back to new condition, but a tank damaged by vacuum or impact can usually be repaired to a sound, workable state. Where the base has been repaired too many times, we replace it on site.
Can you work from our drawings?
Yes. We can build from your design, or develop one from your process and site. Either way, we model it in 3D first so you can see the finished equipment before fabrication starts.
