- Sodium hypochlorite tanks, uPVC (PVC) and UV-stabilised HDPE, bulk and dosing.
- Alum dosing tanks, Liquid alum coagulant for water treatment.
- Glycol tanks, HVAC, brewery, food processing glycol storage and expansion.
- Effluent tanks, Industrial wastewater storage, equalisation, pH adjustment, settling.
- Truck & trailer tanks, Water cartage, dust suppression, fuel transfer, field spray.
- Tank liners & relines, HDPE/PP liners for galvanising, plating and chemical dipping tanks.
- Custom & one-off tanks, Pillar page covering full design-fabricate-deliver workflow.
How we work
The same five step process on every job, from first contact to delivered fabrication.
- Brief and specifications review. Send drawings, specs, an SDS or a written description of the duty. An engineer reviews every enquiry. Site visits by arrangement on confirmed projects.
- Engineering design. Material selection, wall thickness calculations, CAD fabrication drawings, weld plan and inspection and test plan. You sign off the design output before fabrication starts.
- Material procurement. Certified plastic stock, traceable to mill certificates where required.
- Fabrication. Brisbane workshop under ISO 9001 control. Welders qualified to DVS 2207, in-process inspection, pressure or leak testing as applicable.
- Delivery and documentation. Crated, palletised or oversize transport Australia-wide, with on-site fit-up where scope requires. Material certificates, weld records and test results are handed over with the job.

Standards we build to
| DVS 2205 | German thermoplastic tank design standard, static design calculations, wall thickness, chemical resistance, and structural verification for plastic tanks and apparatus. Applied as the design baseline for every tank we fabricate. |
| DVS 2207 | German plastic welding standard, welder qualification, weld procedures, and weld testing for thermoplastic fabrication. Significantly more stringent than minimum AS/NZS welder qualification. |
| ISO 9001:2015 | Quality management system. Industrial Plastics is independently certified by SGS. |
| AS/NZS 4766 | Polyethylene storage tanks for water and chemicals, design, construction, testing. |
| AS/NZS 4020 | Products in contact with drinking water, long-term safety. Applied on potable applications. |
| AS/NZS 4129 / 4130 / 4131 | Polyethylene pipe and fittings, specifications and qualification for plastic pipework integrated with tank installations. |
| AS 1940 | Storage and handling of flammable and combustible liquids, informs bund design and venting on fuel and chemical containment. |
| FSANZ Standard 1.4.3 | Articles and materials in contact with food, applied on food-grade tank applications. |
Sectors we serve
We fabricate for mining, water treatment, food processing, energy and galvanising and powder coating. Each industry page sets out the scope we deliver, the standards that apply and named project examples. For the full list, see Industries we serve.
Why Industrial Plastics
Industrial Plastics has fabricated engineered thermoplastics from its Brisbane workshop since 1971. Every job runs under an SGS audited ISO 9001:2015 quality system, with welding by DVS 2207 qualified welders and per weld traceability, standards that sit above the AS/NZS minimums. Process and project engineers review every enquiry, and every delivery carries its documentation: material certificates, weld records, inspection and test plans, and as built drawings.
The workshop at Hemmant covers 2,000 square metres with hardstand for full volume hydro testing. Local, national and international shipping is available.
Frequently asked questions
Chemical storage tanks for acids, caustics, hypochlorite, alum, ferric chloride, glycol and ammonia, plus dosing day tanks, effluent tanks, glycol tanks, truck and trailer tanks, tank liners and relines, bunds, and fully custom one off tanks. The material is matched to the chemistry.
Tanks are designed to DVS 2205 and AS/NZS 4766 and welded to DVS 2207 by qualified welders. Potable applications are fabricated to AS/NZS 4020 and food contact applications to FSANZ Standard 1.4.3, under an ISO 9001:2015 quality system certified by SGS.
It depends on the chemical, concentration, temperature and UV exposure. HDPE is the workhorse for chemical storage and water, polypropylene suits hotter service, and PVC and PVDF cover specific chemistries. Send the SDS and duty and we confirm the selection.
Yes. Polyethylene pipe and fittings integrated with tank installations are covered by AS/NZS 4129, 4130 and 4131.
