4C SAFE™
4C SAFE is a steel-framed system built entirely with Class A and ignition-resistant materials, engineered for resilience against fire, moisture, mold, pests, and severe weather. Its WUI-compliant exterior walls are available in 1-hour and 2-hour fire-rated assemblies.
Built for places where resilience matters most.
4C SAFE is our steel-framed system for projects where resilience matters most. Built entirely from non-organic, Class A, ignition-resistant materials, it resists fire, moisture, mold, pests, and severe weather. With WUI-compliant, fire-rated exterior walls, SAFE supports Types I-V through traditional design, permitting, and inspections.

Maximum fire protection
Fire-resistant construction, rated 1-HR and 2-HR fire-resistive and WUI compliant, for projects where fire risk is the top design constraint.
Applies to every construction type
Steel framing makes SAFE suitable across all construction types, from single-family homes to larger multifamily and commercial projects.
Same manufacturing speed
More performance, not more cost.
Already rebuilding California's fire-affected communities.
4C SAFE™ is the system behind our fire rebuild program in Altadena and the Pacific Palisades, and was first installed on our Borrego Springs project. Every 4C SAFE™ build is delivered through our network of partner architects, GCs, and developers.
