Our fire-resistant shipping container houses exceed standard fire ratings through multiple protective systems. The construction incorporates: intumescent paint coatings expanding at 200°C to protect structural steel, ceramic fiber blanket insulation (withstand 1260°C continuous), and fire-rated wall assemblies achieving 2-4 hour protection (ASTM E119). All penetrations are sealed with firestop putty and collars, while electrical systems use mineral-insulated copper cables. Doors feature: self-closing mechanisms, fusible link releases, and ceramic glass viewports. The designs include: protected egress paths, photoluminescent exit markings, and automatic fire suppression system prep (wet/dry pipe options). Special hazardous area configurations offer: spark-proof fixtures, explosion venting panels, and combustible gas detection systems. The container's inherent steel structure provides superior fire resistance compared to wood-frame construction, with our enhancements creating defensible spaces in wildfire zones. All fire-resistant models come with third-party certification reports (UL, NFPA) and meet IBC Chapter 7 requirements. For projects requiring specific fire performance ratings or industrial fire protection, consult our fire engineering specialists.
