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
  • Noisey 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: a cleaner system that holds the fabric more consistently and gives the finished shelter a noticeably sharper appearance.

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

Project Spotlight

Large-scale commercial shelter systems designed for demanding real-world environments.

VIP Frame and Truss 103 metre Big Bertha container shelter in Christchurch
Project Spotlight VIP Frame & Truss Christchurch, New Zealand

One of our largest commercial installations to date.

91m Overall length
16m Clear span
1,470m² Protected area
Timber Manufacturing industry

The project

Large-scale protection without compromising access.

When VIP Frame & Truss needed large-scale weather protection for timber storage and production, they required a solution capable of spanning an exceptional distance while remaining practical, durable and economical.

The result was a 91-metre-long Big Bertha installation providing uninterrupted covered storage, unrestricted access for forklifts and heavy vehicles, and dependable year-round protection for valuable timber products.
