20FT Mobile Office Container (Job Box)
On-Site Productivity, Reinforced by Design.
This 20FT Mobile Office Container, also referred to as a job box, is a fully insulated and climate-controlled workspace engineered for rugged field environments. Constructed from a standard ISO-grade 20FT CORTEN steel shipping container, it delivers secure, portable, and operationally ready office space suitable for remote project supervision, construction site coordination, and field-based administrative needs.
The structure is internally finished with commercial-grade materials, equipped with a complete electrical system, and includes HVAC for year-round temperature regulation. It is easily deployable with tilt-bed trucks or forklifts and built to withstand repeated relocation.
