Non-Combustible Steel Construction

Safety Storage S and SE Series buildings, non-combustible steel construction, are a free standing, relocatable chemical storage and containment structure.  The structure includes the following components for storage of flammable or combustible liquids and other hazardous materials.

Safety Storage S and SE Series buildings are designed to meet or exceed the current building code requirements in the jurisdiction in which it is delivered.


Exterior Wall Construction:  Weatherproof unitized noncombustible steel construction fabricated from welded & corrosion-protected structural & heavy gauge steel sheets for maximum durability, weather resistance & rigidity.

Sump Wall Construction:  Weatherproof noncombustible construction, utilizing continuously welded heavy gauge steel sheets for maximum spill containment protection.

Roof/Ceiling Construction:  Weatherproof unitized noncombustible steel construction, same as exterior walls, fabricated from continuously welded heavy gauge steel roof sheets for maximum durability, weather resistance & rigidity.  Roof/ceiling assembly permanently attached to exterior walls.

Non-Combustible Steel Construction with Explosion Relief Panels – SE Series

Explosion Relief Construction:  Includes vent panel(s) located on back wall per NFPA 68 requirements.
