The rugged steel structures are made to take the beating that some worksites deliver. Available in variable sizes, get just the amount of office, or of storage that you need! It's an easy way to keep your worksite organized, even keeping the documents you need right on site.

Our fleet is serviced by trained SiteBox Storage technicians and has solid floors, good corners, and weather-sealed doors. Our lease terms start at just one month with timely maintenance for issues like tires, weatherproofing or brake maintenance–which means very little downtime for you.
