Ramim's S-280C/G shelter is constructed of foam and beam sandwich panels which consist of a polyurethane foam core, aluminum skins and a framework of high strength aluminum alloy extrusions. Structural strength is assured by orientation of the floor and roof beams in transverse direction. This construction provides high strength to weight ratios and facilitates ease of modification, repair and maintenance.

Thick inner and outer floor skins (0.05 inch) lends added strength to withstand increased personnel or equipment traffic. Shelter corners are reinforced to accept leveling jacks and to withstand side loads, imposed by high wind velocities.
