Transports easily

The MSS90 Series 20 is constructed of lightweight structural aluminum. Its design minimizes the use of standard bolts and nuts in favor of field-friendly pins with tethered cotters. A shelter with all of its components, in a typical configuration, fits into one – two 20-foot ISO container.


The MSS90 Series 20 is built to configure to your project specifications. The modular design supports variable lengths. Flat gable and “Big Mouth Door” end options allow appropriate entry access. Insulation or solar panel options are available, as well as an NEC Class 1, Division 2-compliant electrical system for aircraft hangar applications.


Since their introduction, MSS shelters have been successfully deployed in missions all over the world, satisfying the needs for aircraft hangars, vehicular maintenance services, warehouses, housing, and recreational facilities. Because of its versatility, the MSS is uniquely qualified to fit the needs of first-response missions on a myriad of levels.

Deploys Rapidly

The MSS90 Series 20 is both rapidly deployable and relocatable. The shelter is designed so six untrained workers can install the shelter in less than 24 hours with standard tools and no additional special equipment. This ease of construction means the structure can be relocated quickly as necessary.


To endure extreme climate conditions, the MSS90 Series 20 is rated for 100 mph (161 km/h) Basic Wind Speed, Exposure Class C and 15 psf (+/- 75 kg/m²) Ground Snow Load, both per IBC 2006 (ASCE 7-05).


A typical shelter, with all its components – two personnel doors, all tools needed for installation, a ventilation package, a lighting package, and a complete electrical system ready for connection to your power supply – ships complete in one – two 20-foot ISO container.
