20ft x 7ft 6in Steel Mobile Anti – Vandal Office
Looking for a 20ft mobile anti – vandal office that goes wherever your project does? This steel mobile office combines the security of a fixed site cabin with the flexibility of a towable trailer, making it one of the most practical welfare and office solutions for contractors working across multiple or temporary locations.
Built entirely from steel, the cabin is designed to withstand the demands of construction sites, utility works, roadworks and pipeline projects. When the site is unattended, lockable steel shutters seal the windows and a reinforced steel door with heavy – duty deadlocks secures the entrance – keeping tools, plans, laptops and site documents safe from theft and vandalism.
Why choose a anti – vandal office trailer over a static cabin?
Unlike a standard jackleg or static portable office, this unit is mounted on a twin – axle chassis, so it can be towed directly between sites without needing a crane or HIAB lorry for every relocation. That makes it a popular choice for:
- Utilities contractors moving along a pipeline or cable route
- Roadworks and highways teams who need to relocate weekly or even daily
- Groundworks and civil engineering contractors on multi – phase sites
- Local authorities, MOD and police requiring secure, mobile welfare units
- Any site where access for a conventional delivery lorry is restricted
