US Hazmat Storage manufactures prefabricated chemical storage buildings and lockers for flammable, combustible, corrosive, and specialty inventories. Choose fire-rated or non-fire-rated construction, then size the room around drums, totes, pallets, or process equipment. Every building ships from Boone, North Carolina with containment, documentation, and a path to NFPA 30, OSHA, EPA, and local fire-code review.

Questions facility teams ask
When do I need a fire-rated chemical storage building?
Use 2-hour or 4-hour construction when the building sits close to occupied space, property lines, or other structures and the authority having jurisdiction will not accept outdoor separation distance alone.
What is the difference between a locker and a building?
Lockers are compact outdoor rooms, typically for a handful of drums. Buildings are walk-in or forklift-served rooms for larger inventories, tote handling, mixing, or climate control.
Can you convert a shipping container?
Yes. Connex and ISO conversions add sumps, lining, ventilation, electrical, and listings so a container becomes a chemical storage room instead of a dry box.
