Our Super Heavy Duty (SHD) Container Shelters are NZ engineer certified to meet and comply with AUS/NZS 1170.2:2011 wind load ratings (“C” cyclonic) 249kms p/h and to withstand New Zealand’s variable weather conditions. We insist on using fully hot dip galvanised and rolled, 3.2mm gauge structural steel portals and Rip Stop, Heavy Duty, UV stabilised, 610gsm, PVC bonded covers – NOT 280gsm, polyethylene (PE) covers and nor are wire bracings required as with most others. When comparing our shelters please note the additional number of portals and purlins used which provide added strength, durability and of course safety. We truly believe there are no other products available that meet Container Shelters level of value, quality, serviceability and longevity.

Our full end walls and half end panels are optional for all shelters and now feature mechanical wind-up/down doors – not just zips like the others!

All of our products come with our industry leading 10 Year Warranty and complete, ready to assemble and include easy to read & follow comprehensive, assembly instructions.

Why would you risk buying any non-rated shelter or shed when a new Container Shelter costs less and will easily cope with the worst Kiwi weather event? We recommended our Super Heavy Duty range first for safety and usage in the Cook Strait region, Chatham Islands, Stewart Island, Fiji and the tropics. In fact, anywhere that has high wind velocity and even snow events. when you require superior protection for your investments!
