The combination of materials means that the Fibopost can perform in extreme conditions of both cold and heat maintaining it's characteristics up to 140°C it will not melt until +220°C and even in temperatures below -40°C will still perform.
Fibopost will not rust or corrode like steel Star pickets nor will it rot or decay and is impervious to insect attach unlike timber .
The average lifespan of a PET thermoplastic (polyethylene terephthalate) plastic bottle disposed in a landfill is more than 700 years this means the part of the post in the ground is going to be there a very very long time , the bit exposed will outlast all other polymers.
Testing in Arizona PET + 30% glass maintains 99% of it's strength after 1095 days (3 years)exposure and still going strong.
