Coronavirus (COVID-19) Victoria Stage 4 Restrictions


Following on from the Victorian Government’s Stage 4 Restriction announcements, we advise all customers that we are open and able to manufacture and deliver your orders.
We have updated our existing COVIDsafe operating plan to meet the new, more stringent requirements mandated by the State Government. We can get through these tough times together by continuing to service our customers with support from our suppliers while meeting the challenges before us. 
This has involved increasing our sanitation and cleaning on site, enforcing the wearing of face masks, limiting entry of sub-contractors and visitors, restricting off-site movement of staff and contact-less goods receiving and dispatch.
Through the efforts of our team, we are proud to be maintaining our lead times and quality standards while supporting so many other essential industries that we supply into. Our broad range of customers includes those involved in major infrastructure projects, marine and road transport equipment manufacture, agriculture, building & construction, waste collection and pipelines.
Rest assured that we will remain a key supplier and partner to your business.  Do not hesitate to contact us if you have any queries.

Matrix Garden Edging


Matrix Plastic Garden Edging is suited to all climatic conditions and will never rot, rust, swell or leach out the colour. It is not affected by continuous exposure to soil, moisture and salt and will not affect plants or stain paving materials.  For more information on this product range please click on the Matrix Garden Edging link at left.

Matrix Garden Edging is available in two types - Moulded and Extruded.


Moulded Garden Edging is injection moulded from 100% recycled polypropylene (PP) plastic in individual panels in several different designs. See the Moulded Garden Edging page for more details.


Extruded Garden Edging comes in 10m rolls in simulated wood finish. It is made from 100% recycled High Density Polyethylene (HDPE) plastic.  See the Extruded Garden Edging page for more details.




Matrix Pickets product range includes solid plastic pickets with galvanised & powder coated posts, rails and gate frames. They are tough, long lasting and, unlike traditional picket fencing, never need painting. Due to the non-stick nature of the plastic, graffiti washes off easily.  For more information on this product range please click on the Matrix Pickets link at left.


Matrix picket fencing is available in two types: permanent and portable.  


Matrix Permanent Picket Fencing is ideal for use in public spaces and commercial applications due to their toughness and extreme resistance to vandalism.  It is also perfectly suited to residential front fences and gates.  Simple and quick installation of pre-assembled fence panels and gates will produce professional results with a minimum of time and effort. 


Matrix Portable Picket Fencing is ideal for use during events such as exhibitions, parties, rallies, sports, etc. whenever an attractive temporary partition between areas is required.  Matrix Portable Picket Fencing is also perfect for surrounding outdoor areas in cafes and restaurants, as it can be put away at closing time. Matrix Portable Picket Fencing is light and durable and requires no maintenance other than an occasional rinse to get the dust off.  Because the posts are separate from the fence panels, Matrix Portable Picket Fencing is easy to transport and takes up very little space in storage.

Matrix Walkway Panels


Design Flow manufactures in Australia plastic Walkway Panels 1200 x 400 x 40mm from either virgin or recycled Polypropylene Copolymer resin (PP) in a range of 4 colours.  They are available at Bunnings under the Matrix Fast Floor brand.


Matrix Walkway Panels are used in many applications where a non-slip pedestrian surface is required, including jetties, pontoons, boardwalks, pedestrian bridges, viewing platforms, farm sheds, ramps, etc. They are light weight but very strong, with each panel able to support 1500kg when correctly installed.  


Matrix Walkway Panels meet the requirements of Australian / New Zealand standards for load bearing capacity and slip resistance.  Click on the Walkway Panesl link at left for more details.

Matrix Ground Mats


Design Flow manufactures in Australia plastic Ground Mats (also known as Bog Mats) 2400 x 1200mm and 2400 x 600mm from recycled High Density PolyEthylene (HDPE) in a range of colours.  Standard thicknesses are 10mm, 12mm and 19mm, and non-standard sizes or thicknesses can be manufactured.  Joiners are available in 2-way and 4-way configuration to allow mats to be joined to form a continuos roadway or a large pad.


Matrix Ground Mats are used to protect grass and soft ground from vehicle tyres and to prevent vehicles from getting stuck in soft ground.  2.4x1.2m mats have over 1600 studs on each side; one side provides grip to the tyres or tracks, while the other side grips the ground to stop the mats sliding.
They are moulded from a special grade of UV-stabilised recycled polyethylene resin which is designed for long outdoor life.  The material used allows the mats to flex without breaking even under the weight of a heavy truck, while being rigid enough to spread the wheel load.

Matrix Panels


Design Flow manufactures in Australia solid plastic sheets 2.4x1.2m from 7mm to 60mm thick under the Matrix PanelsTM brand.  Matrix Panels are manufactured from either 100% post-industrial recycled polymers or 100% virgin (new) polymers.  


Design Flow manufactures Matrix Panels from PolyEthylene (PE) and PolyPropylene (PP) polymers.  Recycled High Density PolyEthylene (HDPE) and virgin Linear Low Density PolyEthylene (LLDPE) are available in a range of colours in either smooth or textured surface finishes. Low Density PolyEthylene (LDPE) and PP sheets are available in either virgin natural (white) or recycled black.  Matrix Panels are also available as 3-layer sandwich sheets and multi-coloured JAZZ sheets.

Matrix Panels are totally waterproof and resistant to most chemicals and UV light.  They can be saw cut, drilled, machined and plastic welded into various shapes to suit your application. Design Flow offers 2D CAD product design and CNC machining services.

Pallet Separators

Matrix Pallet Separators are solid plastic panels 2000x1130x6mm with rounded edges and a recess at the bottom for forklift tine entry. Matrix Pallet Separators are used by transport companies to create a barrier between adjacent pallets of goods in order to protect them from each other or the forklift during truck loading and transportation.  
Matrix Pallet Separators prevent costly packaging damage, spillage, loss and contamination of palletised goods, especially in the food and grocery sector.  They are also ideal for protecting goods packed in bags, for example polymers, cement and stock feed.
Matrix Pallet Separators are injection moulded from 100% recycled Polypropylene (PP) and are much tougher than plywood and coreflute.  They are also significantly safer for manual handling due to their rounded edges, grip ridges and no possibility of splinters.
They can be hot foil stamped with your company name or logo to reduce the likelihood of loss or theft.
They will outlast plywood by 6-10 times, making them much more economical.  We will even buy back at scrap value any damaged Matrix Pallet Separators for recycling.
