20ft Insulated Storage Container – Steel Lock Boxes

Overview

Give inventory, tools, and household goods an enclosed storage space with added protection against outdoor temperature swings. This insulated steel container combines a compact footprint with double-door access, passive ventilation, and protected locking points. It suits commercial yards, project sites, and residential storage needs without requiring assembly.

Insulation slows heat transfer and helps reduce condensation. This is not a refrigerated container, and it does not maintain a selected temperature. For goods with strict storage-temperature requirements, confirm their requirements before choosing passive insulated storage.

Materials & Build Quality

A structural steel frame supports corrugated, 14-gauge Corten steel walls. The source describes insulation across the walls, roof, and floor, with polyurethane foam or fiberglass batting identified as the wall and ceiling insulation options. The specific material installed needs confirmation.

Weather seals around the rear doors help limit rain and dust entry. Passive wall vents encourage air movement, while welded exterior steel lock boxes help protect padlocks from cutting and tampering. The treated marine-grade plywood floor provides a durable surface for stored equipment and palletized inventory.

The rear doors swing through 270 degrees to clear the loading area. Photo notes show an empty interior with white lining panels and ceiling lights; electrical supply details are not provided.
