FlatBox USA Storage Unit

Storage Unit

What Is the Flatbox USA Storage Unit?

The Flatbox USA Storage Unit is a flat-pack steel storage container designed for residential, commercial, and job-site storage. Each unit features 20-gauge corrugated steel panels, a powder-coated finish inside and out, a marine-grade subfloor with black rubberized coating, a T-Handle locking system, and forklift pockets for repositioning. 

It comes in six sizes, from the compact 5' to the 19', with side-door or end-door configurations. Every unit ships flat-pack to keep freight costs down and assembles on-site, so it’s practical for backyards, job sites, and locations with limited access.
