20ft Used Standard Shipping Container — Wind & Watertight, COR-TEN Steel (Used)

Description

The 20ft Used Standard Shipping Container from Atlas Container Supply is a durable, wind- and watertight steel unit engineered for secure, long-lasting performance.

This 20ft used standard shipping container is a used ex-shipping-line unit in Wind and Watertight (WWT) condition, carefully selected from reputable former shipping lines and fully inspected before dispatch. 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. Expect normal service wear including minor dents, surface marks, and paint weathering consistent with prior shipping use — the unit is structurally intact and ready for immediate storage use on delivery.

The container is built from COR-TEN weathering steel throughout — frame, cladding, and corner castings — which develops a stable surface oxide layer that resists further corrosion in outdoor environments without ongoing maintenance. The floor is 28mm marine-grade plywood on steel cross-members, providing a stable, load-bearing surface for palletised goods, equipment, and bulk materials. Both cargo doors are fitted with two locking bars each for secure closure. Built-in vents promote passive airflow to reduce condensation buildup during storage.

An optional rub-down and RAL respray is available at additional cost — a practical upgrade for buyers who need the container to match site branding, fleet colors, or a specific aesthetic. Specify your preferred RAL color at time of order if requesting this option. For guidance on container siting and permit requirements in the USA, refer to the International Code Council building standards reference.

Construction & Durability

Construction is cargo-worthy steel graded wind- and watertight throughout. On this 20ft steel shipping container 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 20ft steel shipping container 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.
