Site-specific engineering and final dimensions may vary according to location, exposure and mounting method.

Mounting options

One width, mounted your way.

Mount inside to inside for the full 12m clear span, or outside to outside to bring the containers under cover as well — which reduces the clear space between them to approximately 7.64m. Either option works on single or double-stacked containers.

Inside to inside mounted 12m container shelter, single stack Standard

Inside to Inside - Single Stack

The shelter mounts to the inner edges of the containers. The quoted 12m span is the clear space between them.

  • Our standard configuration
  • Span measured between containers
  • Lowest overall height
Outside to outside mounted 12m container shelter, single stack

Outside to Outside - Single Stack

The shelter mounts to the outer edges of the containers, so the containers sit under cover as well. The clear space between them is approximately 7.64m.

  • Approximately 7.64m between containers
  • Containers protected under the roof
  • Lowest overall height
Inside to inside mounted 12m container shelter, double stacked

Inside to Inside - Double Stack

Mounted inside to inside on containers stacked two high, for extra height clearance under the shelter.

  • Extra height clearance
  • Span measured between containers
  • Two containers high
Outside to outside mounted 12m container shelter, double stacked

Outside to Outside - Double Stack

Mounted outside to outside on double-stacked containers, bringing the containers under cover with maximum height clearance.

  • Containers under cover
  • Extra height clearance
  • Two containers high

The Container Shelters difference

KeeperTrack

12 Years of Continuous Improvement.

2016 Previous generation
Earlier Container Shelters end wall edge fixing system

Industry standard edge fixing

Our earlier end wall system relied on a more conventional edge-fixing method.

  • More visible fabric movement
  • Less consistent long-term tension
  • Noisy in a wind event
  • More manual adjustment
2026 KeeperTrack today
KeeperTrack continuous bead in an aluminium extrusion

KeeperTrack

A Keder bead slides into a precision aluminium extrusion for a cleaner, tighter finish.

  • Maintains more consistent fabric tension
  • Cleaner, more premium appearance
  • Reduced movement in strong winds
  • Silent in a wind event

Built from more than 12 years of real-world experience.

After supplying thousands of shelters, we redesigned the way our end walls attach to the container. KeeperTrack is the result.

We don't just sell shelters. We continually improve them.

Project Spotlight

Purpose-built cover for sites with real constraints.

Two 12m x 80ft container shelters at a WM gypsum processing site
Built to Perform. Proven in the Real World. WM New Zealand Tirohia, New Zealand

One of several shelters delivered across a multi-stage programme.

12m Clear span
2 x 80ft Shelters deployed
591m² Protected area
Waste & Recycling Sector

The project

Built heavier, because the site demanded it.

WM needed covered processing space to support an expansion of their gypsum recycling operation. Two 12m x 80ft shelters were deployed, giving continuous clear span for loaders and material handling without internal columns getting in the way.

The site sits in a lee zone, so the whole installation was specified well above standard — heavier structure, closer spacing and upgraded fixings — to handle the wind loads that come with that classification. This was one of several shelters we have delivered for WM across a staged programme, with further stages to follow.
