Fire-Proof Filing Cabinet Frequently Asked Questions
Engineering guidance, custom options, and regulatory compliance details for our custom sheet metal fire cabinets and industrial enclosures.
UL 72 1-hour and 2-hour fire endurance ratings specify how long an industrial cabinet can maintain internal temperatures below critical thresholds (typically 350°F / 177°C for paper or 125°F / 52°C for digital media) when exposed to standard furnace temperatures up to 1850°F (1010°C). A 2-hour rated cabinet features thicker double-wall insulation, reinforced structural ribs, and multi-layered intumescent perimeter seals to double the protection window for sensitive electronic components or hazardous contents.
