40ft High Cube Shipping Containers

Product overview

A 40ft used high cube shipping container — also called a 40-foot used high cube conex box — is a pre-owned steel unit you own outright with an extra foot of vertical clearance for oversized cargo and tall storage needs. The 9'6" exterior height gives you more usable space than a standard 40ft used container at a lower price than new or refurbished.

Are used high cubes reliable? Each unit is carefully inspected to ensure it is wind and watertight and structurally sound, with operational doors, floors, and seals. Built from corrosion-resistant Corten steel to ISO standards with marine-grade plywood flooring and secure cargo doors.

Expect cosmetic signs of prior service — dents, surface rust, and original markings — without affecting performance. Ideal for warehouses, construction sites, retail overflow, agricultural storage, auto parts storage, and modular housing projects where height matters. Units ship in stock for nationwide delivery, giving you secure steel storage on a timeline that matches project deadlines without waiting on custom lead times.
