Description
The 3m x 4.2m Side-Linked Flat Pack Container from Big Bear Containers is a premium, wind- and watertight steel unit engineered for secure, long-lasting performance.
This 3m x 4.2m side-linked flat pack container bundle (galvanised) consists of two 3m galvanised steel flat pack storage units and one galvanised side-by-side linking kit, assembled with the two units joined along their long sides to create a wide, almost-square combined footprint of 2.95m × 4.37m external. It is the compact equivalent of our 4m x 4.2m Side-Linked Galvanised Bundle — providing the same wide open-plan layout in a shorter, lighter package suited to sites where the 4m length would be impractical or excessive.
With a combined internal width of 4.07m, this bundle creates a usable floor area of approximately 2.80m × 4.07m — well suited to storing wide or bulky items such as insulation rolls, sheets of board material, garden furniture, and large sports equipment that a single narrow-profile unit could not accommodate. Each unit retains its own door in the assembled structure, providing two separate key-lockable access points. Doors can be configured at the same end for a unified access front or at opposite ends to allow independent access into each half of the structure.
The bare galvanised steel finish provides corrosion resistance through the zinc coating without a painted topcoat — functional and durable in outdoor environments where appearance is secondary to longevity. The flat-packed bundle is manageable without crane or forklift assistance — components pass through narrow access points and can be transported in a standard van or flatbed trailer. Assembly requires only a socket set.
Note: flat-pack containers can only be joined in one direction — side-by-side or end-on-end — within the same structure. Additional units and linking kits can be added to expand storage capacity further. Contact Big Bear Containers to discuss multi-unit configurations.

Ideal Uses

- Rapid-deploy storage and site rooms
- Temporary offices and welfare units
- Secure tool and equipment stores
Construction & Durability
The 3m flat pack unit is built from factory-fresh one-trip steel — corrugated Corten panels that weather to a stable oxide layer instead of rusting through. Corner castings are forged and welded to the rails, so it can be lifted, stacked, and relocated without the frame racking out of square.
Delivery & Site Preparation
Delivery is a flat rate by region from our Sacramento yard – local, nationwide and international – and the exact rate shows at checkout. Allow about 75ft of clear, straight approach so the bed can tilt and slide the unit off. Have the drop zone marked and clear on the day — the driver sets it once, and moving it afterwards means another truck.
