• Durability – The plastic used is heat stabilised.  Furthermore it has been UV stabilised for in excess of 10 years (they wont melt in the sun nor will UV affect them);
• Sturdier and lighter – They are lighter but sturdier than the metal equivalent which allows them to start up more quickly.  Slow start up can result in leaks;
• Beautiful – The quality is exceptional. Expect an aesthetically very pleasing product.  The colour is in the material so can’t and doesn’t peel off;
• Exceptionally free moving and squeak free – The 2 x Sealed bearings make this unit exceptionally free moving – starts in a whisper of a breeze;
• Flexible – the plastic is slightly flexible and is unlikely to dent in most hail storms;
• Theft “proof” – the plastic does not have a scrap value so they are unlikely to be stolen – theft it is a real issue with anything metal;
• Chemical tolerant for highly corrosive environments; and
• Comprehensive 5 year guarantee
