The temperature at which wood framing can ignite in a wildfire.
Light-gauge steel framing doesn't ignite - it can't feed a fire the way wood does.
The highest fire rating a roof can carry - the standard we spec for fire-country builds.
Material properties shown for general reference. Every project is engineered to site conditions and applicable California building codes, including Chapter 7A WUI requirements where they apply.
Most homes in Southern California's wildfire zones are framed in wood - the same material fires consume. Fast Struct builds differently. Whether you're building a new home from the ground up or adding an ADU, the structure is light-gauge steel: non-combustible, dimensionally stable, and precision-cut to millimeter tolerances in our state-approved California facility.
Around that steel skeleton we build a fire-resistant envelope: a fire-resistant stucco exterior and Class A roofing - the materials fire-country building science calls for, engineered as one system.
Your lot, your design, your finishes - built for wildfire country.

Typical Wood-Framed Home
Fast Struct Steel Home
Fast Struct was built on a simple conviction: California homes should be faster to build and harder to destroy. So we moved construction into a state-approved factory and switched the structure to light-gauge steel.

Install day - one crane, one dayToo many Southern California families have learned how long a conventional rebuild takes.

One dedicated project manager Permits, design, fabrication, and delivery - handled end to end.

Why Fire-Country Homeowners Choose Fast Struct
Light-Gauge Steel - Not Wood
Every Fast Struct home is framed in light-gauge steel - our specialty. Steel is non-combustible, doesn't rot, and holds millimeter-level tolerances. It's a fundamentally better building material - and one that 90% of our competitors simply can't offer.
Fire-Resistant Stucco + Class A Roof
The envelope matters as much as the frame: a fire-resistant stucco exterior system and Class A roofing, engineered to resist the ember attack that ignites most homes in a wildfire.
As Fast As 90 Days
Off-site factory production runs in parallel with your on-site foundation work, compressing timelines no traditional builder can match.
State-Approved Facility = Faster Permits
As a state-certified modular factory, our plans go through the state approval route - permits in days, not months.
Homes and ADUs
From a full custom home on your lot to a backyard ADU, every project gets the same fire-smart materials and factory precision.
