Industries We Serve: Stainless Steel Process Equipment for Australian Manufacturers
Stainless Tank & Mix is a Sydney-based stainless steel process equipment manufacturer, designing and building tanks, silos, mixers, blenders and turnkey systems for Australian manufacturers since 1974. From individual vessels to complete process equipment projects, our team fabricates and develops equipment around production needs, site constraints and operating conditions.
Every industry brings its own specifications for hygiene, materials, fabrication, testing and documentation. Food and beverage equipment may need hygienic design and cleanability, while pharmaceutical applications can call for tighter surface finishes, traceability and documentation. Chemical and industrial processes may place greater emphasis on corrosion resistance, containment, pressure constraints, or material compatibility. Rather than adapting a general fabrication approach to every application, STM considers these factors at the design stage and builds equipment to suit the process and environment in which it operates.
Explore the industries we work with to see how our approach applies to your application. If your industry is not listed, talk to our team about your needs. We can work through the product, process, materials, operating conditions, and documentation involved to determine the right equipment for your application.

Industries We Serve
STM has completed numerous projects for dairy manufacturers, including milk silos, storage and mixing tanks, cheese and yoghurt vats, and batch pasteurisers. Equipment is designed for CIP (Clean-in-Place) cleaning, allowing vessels to be cleaned without disassembly and supporting hygienic production. STM incorporates relevant industry standards and hygienic design principles, including 3-A principles and AS 1692 where applicable. Applications range from smaller batch equipment to large-capacity storage and processing vessels.
Projects
Recent projects include a 1,000 L jacketed batch pasteuriser and 76,000 L hot water silo. Explore STM’s range of dairy tanks and silos for your process and product needs or see our industry solutions.
For the food and beverage industry, STM designs and fabricates process tanks, silos, powder blenders, pressure vessels and pipework systems. Each solution is developed with HACCP principles in mind, supporting the identification and control of food safety hazards, with food-grade finishes where required. STM considers hygiene, cleanability, material selection and process conditions at the design stage, delivering vessels and processing systems suited to liquid processing, powder handling, storage and batching.
Projects
Completed projects include a cereal coating spray bar and control system, seafood continuous product cleaner, 750 L chocolate melt tank, 55 t / 127,000 L flour silo and turnkey food processing system. Explore STM’s industry solutions.
STM designs and fabricates GMP process tanks and IBC mixers for pharmaceutical applications, with consideration for TGA GMP principles, 316L stainless steel, surface finishes of ≤0.4 Ra and comprehensive documentation. For a multinational pharmaceutical company, STM redesigned an IBC mixer after the existing unit showed signs of fatigue and larger batch sizes were needed. Other pharmaceutical solutions include heated mixing tanks, vacuum transfer systems and equipment lifters, developed around hygiene, batch handling and production requirements.
Projects
Other projects include an equipment lifter and vacuum transfer unit, 160 L heated mix tank, and pharmaceutical-grade process tanks. See how STM supports different industries and applications.
STM has designed and fabricated chemical mixing and storage tanks, jacketed vessels, and contra-rotating and high-shear mixers for chemical and cosmetics applications. Material selection is based on the product and process, with 316L stainless steel, duplex grades or Hastelloy material used where required. Pressurised vessels are designed to AS 1210 where applicable, while Ex-rated components can be incorporated for hazardous areas. Each solution is developed around chemical compatibility, mixing performance, temperature control, and safe operation.
Projects
A few projects STM have worked on include: 22,000 L chemical mix tank, 316-grade chemical storage tank, collection mix tanks for a high-end cosmetics company, 3,000 L vacuum contra-mix kettle and an ETFE-lined vessel for chemical recovery. Discover STM’s solutions for your industry.
STM brings process engineering, fabrication and project delivery together under one roof. Capabilities include P&IDs, 3D modelling, FEA, skid systems, automation, turnkey plants and commissioning, helping integrate individual components into a complete process solution.
Projects
Previous work includes turnkey processing facilities, flexible production systems, a mobile skid with a feeder tank for viscous products, and batching and bulk storage systems. By combining engineering and fabrication in-house, STM can develop solutions around your process, site and production needs. Find the right process solution for your industry.
Water treatment solutions include chemical dosing and storage tanks, process and feedwater tanks, trade-waste and permeate tanks, and dosing skids. Material selection can include 316L stainless steel or duplex grades based on chloride levels, while AS/NZS 4020 can be considered for applications involving drinking-water contact. Each solution is developed around the water quality, process conditions and site requirements.
Projects
Some projects STM has worked on include process water storage tanks, 6,000 L boiler feedwater tank, replacement trade waste tank, and 4 × 5,000 L open-top specialty water tanks. See STM’s industry-specific solutions.
STM also works across specialised industries including research, defence, mining and energy, as well as one-off and custom equipment applications. These projects often involve unique operating conditions, tight specifications, or specialised fabrication requirements that call for an individual approach.
Projects
Previous work includes a product lump breaker for a nuclear science organisation, radioactive ore drum loaders, a replacement mobile mix tank for a defence organisation, stainless steel engine after-coolers and a small high-pressure explosive test vessel. STM can work from an existing design or develop a solution around a specific application. See how STM designs for different industries and processes.
Standards and Hygiene by Industry
Different industries require different standards for hygienic design, materials, fabrication, testing and documentation. There is no single Australian standard for the design of dairy or food tanks; these are built to the customer’s specification and the guidelines their regulators require. The table summarises what we typically design and document.
| Industry | Typical standards and requirements |
|---|---|
| Dairy |
|
| Food & Beverage |
|
| Pharmaceutical |
