Is your quote for hot-dip galvanised and rolled, structural steel (that we use) or inferior box section steel?
We use only hot-dipped, heavy gauge, rolled (round) structural steel portals and purlins.
Is the cover 610 gsm, UV stabilised and bonded PVC (the same as truck curtains) or only 280 gsm polyethylene?
Our Rip Stop PVC covers cost us significantly more than lightweight PE covers - but we think It’s worth it - because tensile tests show PVC is significantly stronger, stretches 7 times less and lasts longer than the other lightweight materials on offer.
Is the shelter NZ engineer certified and rated to Very High Wind Zones within AUS/NZS 1170 wind load ratings?
Our heavy duty Container Shelters are manufactured and NZ engineer-certified to meet and comply with AUS/NZS 1170 wind load ratings up to & including Very High Wind Zones.
