About Polymaster: Storage Tank Manufacturers & Suppliers

Home About Us

“Since 1994, my family has believed that resilience is engineered from the ground up. Today, as we continue to lead the business forward, our promise remains the same: whether it’s for a farmer in the Mallee or a Tier 1 mine site in the Bowen Basin, we don’t just supply products; we build partnerships founded on trust.” — Daniel Steele, General Manager

	The Polymaster Difference	Standard Supplier
1. Reliable by Design (Innovation & Quality)	In-house R&D & Engineering Team. We don’t just mould plastic; we engineer solutions. From self-supporting tank roofs to baffled septic systems, our certified designs guarantee strength across every sector.	Sales-only focus. Standard, generic designs often copied or imported with limited technical innovation.
2. Reliable Service (Support & Logistics)	Expert Support for Every Customer. Whether you need a dedicated Project Manager for a mine site or a responsive expert for a farm install, we provide the logistics and technical advice to get the job done.	Transactional. “Delivery at gate” only. Limited technical support once the product is sold.
3. Reliable Partnerships (Trust & Stability)	Global Strength, Local Heart. Backed by the financial stability of Tank Holding Corp, we offer the security of a global leader with the care of a local partner. We will be here to honour your warranty in 20 years.	Uncertain Long-term Stability. Smaller, local-only operators may lack the financial backing to guarantee long-term warranty support.
