Frequently Asked Questions

  • What are the benefits of custom plastic tank fabrication?

    Custom plastic tanks are designed specifically for the intended application, which means better fit, greater efficiency and reduced maintenance over time. Unlike generic tanks, custom builds can be tailored to include specific fittings, inlets/outlets, supports and reinforcements. Using materials like HDPE, these tanks offer excellent resistance to chemicals, corrosion and impact—making them ideal for industrial, agricultural and mining use.

  • Can custom plastic tanks be made for underground or above-ground use?

    Yes, plastic tanks can be fabricated for both underground and above-ground use. Underground tanks often require additional structural support or specific shapes to handle soil pressure, while above-ground tanks focus more on accessibility, UV protection and thermal stability. Design requirements depend on the tank’s application, installation environment and the type of materials it will store.

  • Are custom plastic tanks compliant with Australian safety standards?

    When fabricated by qualified professionals, custom plastic tanks can be built to meet Australian safety and industry standards. This includes compliance with AS/NZS standards related to chemical storage, pressure testing and load-bearing structures. It’s important to work with a fabricator who understands the specific requirements for your industry to ensure the finished tank meets both functional and legal expectations.
