20ft Shipping Container – Matte Black w/ 12’ Side Roll-Up Door

Shipping containers serve many storage and modification purposes. Offered here is a pre-owned 40-foot shipping container graded to a wind and watertight standard. It delivers a substantial enclosed space for secure material storage, job site organization, or as a base for conversion projects, and it has been inspected to confirm the structure holds up against the elements.

Key Features

• Wind and watertight grade: Evaluated so the doors seal properly and the structure is free of large holes or significant gaps, keeping out rain and wind.
• Solid steel construction: Made from COR-TEN steel and built to withstand stacking and heavy loads, providing a robust shell for securing contents.
• Standard double-swing doors: One end has lockable double doors with integrated locking bars for wide interior access during loading and unloading.
• Cargo-ready flooring: The interior floor uses original marine-grade plywood designed to support palletized cargo and heavy equipment.
• Weather-resistant exterior: Retains its original weather-resistant paint. Surface rust and cosmetic dents typical of pre-used equipment are present but do not compromise wind and watertight integrity.

This 40-foot pre-used container is classified as wind and watertight (WWT). It is a practical choice for on-site storage, overflow inventory warehousing, or as a secure enclosure in industrial settings. It is built from weathering steel, commonly known as COR-TEN, which develops a protective patina over time and reduces the need for constant repainting outdoors.

Interior access is through the rear double doors. These are fitted with steel locking bars and forged steel ratchets that pull the doors tightly against the integrated rubber gaskets. Properly sealed, these components create the wind and watertight environment.

Inside, a plywood floor sits over a steel cross-member substructure, capable of supporting concentrated loads such as forklifts or loaded pallets when loading from ground level. The interior walls and ceiling are bare corrugated steel, offering tie-down points within the grooves.

Note that this unit is sold in "as-is" used condition and will show signs of prior service, including scratches, dents, and surface rust. It does not, however, have holes that let daylight through the walls, roof, or floor. The wind and watertight classification covers resistance to driven rain and normal air infiltration only; it is not designed for submersion or pressurized water exposure.
