Poly Synthesis is a Brisbane-based leader in thermoplastic fabrication, delivering engineered solutions using polyethylene (PE), polypropylene (PP), and a wide range of engineering plastics. We fabricate from both sheet and pipe, producing custom components and systems for industrial, civil, mining, water, and infrastructure sectors across Australia.
With deep technical expertise and an adaptive approach, we specialise in high-integrity, made-to-order builds that perform in demanding conditions—where off-the-shelf products simply won’t do.
As a trusted prefabrication partner, we work closely with engineers and contractors to deliver fully assembled, install-ready systems that reduce on-site time and ensure quality outcomes.
Our core capabilities include:
● Custom tank design and manufacturing (chemical storage, dosing, treatment)
● Fabrication of pipe systems and spooling from PE, PP, and engineering plastics
● Thermoplastic welding: butt fusion, electrofusion, and extrusion
● Sheet plastic fabrication and CNC machining for housings, covers, and enclosures
● Bunding, liners, and secondary containment systems
● Wastewater and stormwater solutions, including grease arrestors
● Site services: shutdown works, repairs, and retrofitting
● Custom manifolds, pipe transitions, and specialised assemblies
We’re known for our ability to solve complex fabrication challenges with practical, compliant, and cost-effective solutions.
