Welcome to Design Flow's Matrix Panels Web Site


Design Flow Pty Ltd is an Australian privately owned company established in 2001.  We specialise in the development, manufacture, marketing and distribution of innovative plastic products under the MatrixTM brand. Our products are sold around Australia and overseas to the retail hardware, building, industrial, mining, marine and primary production sectors.


Our products are pided into three main groups: Matrix Screening & Fencing, Matrix Flooring and Matrix Panels.

Matrix Panels are 2.4m x 1.2m plastic sheets manufactured in Australia from either virgin or recycled PolyEthylene (PE) and PolyPropylene (PP) thermoplastic resins in any thickness from 6mm to 65mm, in smooth or textured finish and in a range of colours.  


Design Flow is the only company in Australia that manufactures thick plastic sheets locally - all other major suppliers are importers.


Common thicknesses are available ex-stock in black HDPE, but if we don't have what you need in our warehouse, our lead times times from order to delivery are very short - we are usually able to deliver within 1 week. 


Because we manufacture Matrix Panels in Australia, we can produce custom combinations of sheet thickness, material and colour (minimum order quantities apply - please contact us for a quote).  We can also manufacture Matrix Panels to order in ABS and Polystyrene.



Unlike timber based sheets or panels, Matrix Panels are tough, strong & durable, will not rot, crack, swell, delaminate, mildew or be affected by termites.  Matrix panels can withstand continuous contact with water and corrosive chemicals that would destroy most metals.  UV-stabilised grades are designed for long outdoor life.


Matrix Panels are 100% solid plastic sheets, they are not foamed like some other plastic sheets.  This makes Matrix Panels much stronger and better suited to heat welding using specialized plastic welding equipment, especially for use in manufacture of liquid tanks, pipeline components and other demanding applications.


The consistent properties of Matrix Panels throughout the thickness of the sheet make them ideal for cutting and machining into various shapes.   Matrix Panels can be sawn, routed, drilled and machined using standard equipment and tools made for timber.  The cut edges will look the same as the faces of the sheet.


Standard sheet size tolerance is 2400+40/-0mm x 1200+20/-0mm, sheet squareness tolerance is within 5mm.

Sheet thickness tolerance is ±5% or +/-1mm, whichever is greater.  Sheet thickness can vary within one sheet and between sheets.



Matrix Panels can be used for a huge range of applications in many industries including Agriculture, Aquaculture, Building & Construction, Chemical, Equine, Manufacturing, Marine, Materials Handling, Signage, Transport, etc.  Click on the Applications link at left or go to the Polyethylene and Polypropylene pages for more information.
