40ft Used Standard Shipping Container — Wind & Watertight, COR-TEN Steel (Used)

Description

The 40ft Used Standard Shipping Container from Atlas Container Supply is a rugged, wind- and watertight steel unit engineered for secure, long-lasting performance.

This 40ft used standard shipping container is a used ex-shipping-line unit sold in Wind and Watertight (WWT) condition. WWT means the unit is structurally sound and weatherproof — it will keep wind and water out — but has not been formally re-certified for international shipping. It does not carry a valid CSC plate and is designed for on-site storage use rather than active freight operations. Expect surface marks, minor dents, and paint weathering consistent with prior shipping service — the unit is structurally intact and provides reliable, dry storage immediately upon delivery.

The container is built from COR-TEN weathering steel throughout — frame, cladding, and corner castings — which develops a stable surface oxide layer to resist corrosion in outdoor environments without ongoing maintenance or repainting. The floor is 28mm marine-grade plywood on steel cross-members, providing a stable, load-bearing surface suited to palletised goods, equipment, and heavy materials. Access is via exterior hinged double cargo doors at one end, each fitted with dual locking bars for secure closure. Four vents provide passive airflow through the unit to limit condensation buildup during storage.

At 40ft in length with a cubic capacity of 2,387 cu ft (67.6 m³), this is one of the largest standard ISO storage footprints available — suited to construction sites, agricultural properties, industrial facilities, and commercial operations requiring high-volume secure storage in a single deployable unit. The standard 8ft 6in height profile fits under most standard overhead restrictions and is stackable on a flat hardstanding. Forklift pockets and ISO corner castings allow repositioning by forklift or crane without additional equipment.

Construction & Durability

This 40ft steel shipping container uses cargo-worthy steel graded wind- and watertight over a welded steel underframe with cross-members on close centers, which is why the floor takes forklift traffic without deflecting. The roof is a single corrugated sheet — no seams across the span to leak.

Delivery & Site Preparation

The 40ft steel shipping container goes out on a free tilt-bed run with delivery windows confirmed ahead of the date. A 40ft-class unit needs roughly 100ft of straight approach for the truck to back in and tilt. Gravel over compacted base is the cheapest pad that actually works; bare soil will pull moisture and settle unevenly through a wet season.

Why Buy From Atlas Container Supply

Every unit is inspected before it ships and backed by our 30-day return policy.
