The Future of Construction is Cold-Formed Steel

When planning a new build or ADU, one of the biggest decisions is choosing the right framing material. Traditionally, wood has been the default—but today, Cold-Formed Steel (CFS) offers homeowners and builders a smarter, stronger, and safer alternative.

At Blue Diamond General Contractors, we specialize in designing and building with steel because we believe in giving our clients structures that last for generations.

Steel vs. Wood: The Key Differences

Feature Cold-Formed Steel (CFS) Wood Framing
Fire Resistance Non-combustible, will not ignite Highly flammable, fuels fire spread
Durability Won’t warp, rot, split, or attract termites Prone to rot, mold, and termite damage
Strength Higher load-bearing capacity, great for ADUs & multi-story Weaker over time, less stable in earthquakes
Sustainability 100% recyclable, eco-friendly Requires tree harvesting, less sustainable
Precision Factory-engineered, exact cuts, no waste Inconsistent quality, often requires corrections
Maintenance Minimal long-term maintenance Requires upkeep, pest treatment, replacements

Why More Homeowners Are Choosing Steel

  • Fire Safety: In wildfire-prone California, steel framing provides peace of mind.

  • Longevity: Steel structures last decades longer than wood.

  • Low Maintenance: No costly termite treatments or repairs.

  • Eco-Friendly: Steel is sustainable and reduces environmental impact.

  • Cost Savings: Faster builds, fewer repairs, and stronger resale value.

When Wood Still Makes Sense

While steel is superior in most cases, wood may still be chosen for:

  • Smaller DIY projects with extremely tight budgets.

  • Areas where wildfire and termites are not a risk factor.

  • Temporary structures where long-term durability isn’t required.

But for serious homeowners and developers in California, steel offers unmatched value and protection.
