Description
The 3m x 4.2m Side-Linked Flat Pack Container from Big Bear Containers is a durable, wind- and watertight steel unit engineered for secure, long-lasting performance.
This 3m x 4.2m side-linked flat pack container bundle (powder-coated) is the color-finished alternative to our 3m x 4.2m Side-Linked Galvanised Bundle. Both bundles are identical in configuration, dimensions, weight, and floor specification — the distinction is the exterior finish. This powder-coated version has a coloured topcoat applied over the galvanised steel substrate, providing a sleeker, more refined appearance suited to residential, school, sports club, and customer-facing environments where a raw metallic finish would be visually out of place.
Specify your preferred color at time of order. The powder-coat finish provides an additional layer of corrosion protection on top of the galvanised base, making this bundle particularly well suited to coastal, high-humidity, and chemically aggressive outdoor environments where long-term finish durability is a priority. The combined storage footprint of 11.3m² (121 sq ft) across a 4.07m internal width and 2.80m internal length provides an open-plan storage area suited to wide or bulky items — insulation, sheet materials, large sports equipment, and garden furniture — that a single narrow-profile unit cannot 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 for independent rear access into each half of the structure. The flat-packed bundle weighs 704 kg total, with the heaviest individual component confirmed at 120 kg — manageable by a small team without crane or forklift assistance, requiring only a socket set for assembly.
Units can be linked side-by-side or end-on-end — one direction only within the same structure. Additional units and linking kits can be added to expand the configuration further. Contact Big Bear Containers to discuss multi-unit builds in your specified color.

Construction & Durability
Construction is factory-fresh one-trip steel throughout. On this 3m flat pack unit the door gear is the part that earns its keep: four locking bars into cams top and bottom, seated against a full-perimeter rubber gasket that is what actually keeps weather out.
Delivery & Site Preparation
Site prep for the 3m flat pack unit is simple but not optional. Allow about 75ft of clear, straight approach so the bed can tilt and slide the unit off. Level the pad within an inch or so across the footprint; a container that sits twisted will bind at the doors, which is the one fault that is genuinely annoying to fix later.
