Our NZ Engineer Certified Container Spanz shelters cost less than lower and non-rated conventional shelters and are rated to 249kms p/h – We call it “Super Heavy Duty”… You’ll call it “Peace of Mind!”
No Tuffspan (PE) covers used here!
We are proud to be “The Heavy Weights” in the industry which is why we only use industry-leading, fire retardant, Rip Stop, 610gsm, UV stabilised, PVC covers with optional end walls – the same material chosen by truckies and international transport companies and as specified for The Cloud in Auckland. Wouldn’t you prefer the strongest cover available for less than other companies charge for their lightweight PE covers?
Our Rip Stop PVC covers cost us significantly more than we could buy lightweight PE covers! 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 when continually exposed to the heavy demands and constant high wind/snow loads with large variant weather pressures and events.
Lightweight 280gsm PE or Tuffspan (PE) polyethylene material is not used by us, on The Cloud or for truck curtains for very sensible reasons.
Rolled Steel or “fast mount beam” Box Steel?
An easy question to answer with another question. Why are all high pressure, gas cylinders round? Being round distributes the load evenly throughout the entire steel structure and therefore can handle significantly higher loads and pressures than similar gauge box steel.
We only use heavy gauge, rolled (round) structural steel portals and purlins because we demand our structures will not fail under loads, and we will not compromise on quality for the sake of cheaper box section steel.
Each portal is mounted to a pre-welded spigot and galvanised base plate because that’s simply the strongest mounting method.
Using this method provides a superior tensioning method which in turn, then allows for the equal and constant distribution of stress loadings over the entire area of our heavyweight PVC covers.
These are the reasons why our Heavy Duty Container Spanz shelters are manufactured and NZ engineer-certified to meet and comply with AUS/NZS 1170.2:2011 wind load ratings (“C” cyclonic) 249kms p/h.
Other companies can’t compete with our product knowledge, the strength of the product, quality and prices so their salesman will often use “smoke and mirrors” that can be misleading to the public when searching for the real facts. We urge you to compare because the deeper you look, the more you’ll learn that Container Spanz shelters use more rolled steel portals and purlins combined with the industry’s best covers!
3 Very Important Questions to Answer Before You Buy!
1) Is your quote for hot-dip galvanised and rolled, structural steel or box section steel?
2) Is the cover 610gsm, UV stabilised and bonded PVC (same as truck curtains) or only 280gsm polyethylene?
3) Is the shelter NZ engineer certified and rated to 249kms p/h within AUS/NZS 1170.2:2011 wind load ratings?
Don't be mislead with slick sales talk and "smoke and mirrors"!
PVC vs PE (Polyethylene) Tensile Test Results
Below are independent laboratory test results showing that PVC’s tensile strength is more than double that of PE – with more than twice the elasticity. Also, note that PE stretched nearly 7 times more than PVC before tearing.
|Specimen ID||Elasticity (MPa) calculated from strain 0.05 to 0.25%||Tensile Strength (MPa)||Elongation at Break (%)|
1. Container Spanz shelters PVC covers have more than twice the tensile strength than PE covers.
2. Container Spanz shelters PVC covers have more than twice the elasticity than PE covers.
3. Container Spanz shelters PVC covers stretch approximately 7 times less than PE covers.
4. Container Spanz shelters PVC covers are THE BEST IN THE INDUSTRY – WITHOUT A DOUBT!
