We are familiar with Australia and New Zealand temporary construction fencing through 11 years experience accumulated take this advantage we are always giving right solutions of temporary fencing, when there are customers ask us what is exactly service life you fencing panels ,actually this is very hard questions to answers cause in climates anything is possible but yes ,we can say what is good products and if no force majeure affections and most cost-performance one as an elder temporary fencing company we recommend 42 microns temporary fencing panels, 42 microns is standard thickness of hot-dipped galvanized which was wide accepted by Australia and New Zealand equal to 300gram/sqm zinc but due to recently there are lots of temp fencing hire or rental companies bloom in Australia building industry lots of temporary fencing panels was hire buy 42 microns temporary obviously will lead to a cashflow issue so more and more these companies revert to 14 microns temp fencing but again 42 microns temporary construction fencing is good product cost-efficient products in all market even it is a little bit expensive than 14 microns . In theory, the 14 microns service life is 3 years, so 42 microns 3 times the ability of anti-corrosion, let us say half 5 years
