Why Choose DM Plastics

Why DM Plastics for Irrigation

We start with application engineering – helping you choose the right diameter, pressure rating, colour, coil length and joining method to suit your project needs. When a standard SKU won’t do, our in-house R&D team can adjust lengths and assemblies, within compliance, to produce a suitable, site-ready solution.

 

We manufacture all products locally and back every meter with our ISO 9001 Quality Assurance and in-house testing facilities. Our product range spans rural, metric, LDPE poly pipes and fittings and polypropylene threaded and unthreaded risers, helping you build complete systems from one trusted supplier. When the job calls for something different, our Producing Solutions approach lets us co-engineer specials (identification colours, non-standard lengths) that meets the requirements of any project – no matter how big or small. For long distances, we supply jumbo project coils over 1km in length saving you time and money on transport, joins and installation. Proven performance, Australian made products for Australia’s toughest conditions.

Irrigation FAQs

Rural or metric — which should I use for my application?

Use rural (ID-sized) coils for farm reticulation with standard rural fittings; use metric PE for pump sheds, mains and public landscapes where AS/NZS:4130 and colour identification apply.

When lines are exposed to sun or when delivered water temperature matters (horticulture, livestock). The reflective skin helps manage heat gain and thermal movement on long runs.
Yes – for long distances we offer Jumbo Project Coils (>1km coils). These maximise transport utilisation, reduce fittings, and cut installation time. Unreeling equipment is available for hire on request.
Standard threaded BSP options in 15mm to 75mm with factory lengths from 150mm to 6000mm; special lengths can be supplied to order (priced at the next longest length, MOQ applies). Unthreaded Polpro in straight lengths is also available.

Yes – metric PE (lilac) for recycled water mains and LDPE lilac co-ex for laterals, supporting clear network identification.

Absolutely. Share your duty (pressure/flow/temperature) and block layouts; we’ll recommend pipe classes, coil/length strategy and Polpro risers for neat, serviceable take-offs.
