Engineering Standards & Fabrication Capabilities

When Standard Tanks Don't Fit the Job

Off-the-shelf plastic tanks rarely match the exact capacity, footprint, or fitting layout a job demands. Custom fabrication becomes the practical choice when you're working with irregular installation spaces, aggressive chemicals that require specific material grades, or process systems that need bespoke inlet and outlet configurations.

Perspex Online fabricates tanks to your supplied dimensions and specifications - whether that's a compact 50-litre dosing vessel or a multi-thousand-litre industrial storage unit with internal baffles and a bunded base.

Industries and Applications

Plastic tanks are the preferred containment solution across sectors where metal corrosion is a liability and chemical compatibility is non-negotiable. The material selection - polypropylene , HDPE , or PVDF - is driven by the media being stored, the operating temperature, and the regulatory requirements of the site.

Common applications we fabricate for include:

  • Chemical storage and secondary containment (acids, alkalis, solvents)
  • Electroplating and surface treatment baths
  • Water treatment and dosing systems
  • Mining process and reagent tanks
  • Agricultural liquid fertiliser and chemical storage
  • Wastewater, effluent, and leachate containment

Fabricated in a Professional Plastics Workshop

Perspex Online's tank fabrication is backed by the infrastructure and trades experience of P&M Plastics, a professional plastics fabrication workshop with the equipment and capacity to handle structurally demanding builds. This means access to proper welding rigs, precision cutting, and the ability to manage complex multi-compartment or bunded tank configurations that smaller operations can't support.

Every tank is pressure tested before it leaves the workshop, and site installation is available for projects where positioning, levelling, and commissioning need to be handled on location.

Material Selection Matters

Choosing the wrong tank material for a given chemical or temperature range is a costly mistake. HDPE suits a broad range of general chemical and water storage applications; polypropylene handles higher temperatures and is widely used in process and plating tanks; PVDF is specified for the most aggressive chemical environments where other materials would degrade.

If you're unsure which material grade is appropriate for your application, our team can advise based on the media, concentration, and operating conditions you provide.

Plastic Tank Fabrication FAQ

What types of plastic tanks do you build?
We fabricate chemical storage tanks, water tanks, secondary containment bunds, dosing tanks, mixing tanks, and custom process vessels from 20 litres to 10,000 litres capacity.
What materials are used for plastic tanks?
Most tanks are built from polypropylene or HDPE for chemical resistance. We also fabricate in PVC for specific chemical environments and can advise on the best material for your application.
Are your tanks certified?
We manufacture to AS/NZS 4766 for polyethylene tanks and follow industry standards for welded thermoplastic vessels. Tanks can be supplied with hydrostatic test certificates and weld inspection reports.
Can you add fittings, flanges, and level indicators?
Yes. We install threaded fittings, flanged connections, sight glasses, level indicators, overflow pipes, drain valves, and lifting lugs as part of the build.
Do you offer on-site installation?
We can coordinate delivery and installation for Perth metro and regional WA. Interstate, tanks ship on pallets via standard freight and are designed for straightforward on-site positioning.
